Frikken, P.E.Having one global standard becomes more and more important as companies merge across international boundaries, helped by regional trade agreements such as the North American Free Trade Agreement (NAFTA) and those estab-lished by the European Union (EU), which have facilitatedinternational mergers through the lowering of tariffs onimports.The companies involved in these consolidations, usedto selling to just one market, now find themselves sell-ing to global markets. The standards for products inthese markets are often different, which complicatesmanufacturing procedures. Local laws may require the use of a particular standard, yet these laws are viewed by the World Trade Organization (WTO) as technical barriers to trade, and WTO mem-ber countries are charged with reducing these and other barriers to free global trade.What is the best way for standards-developing organizations like ASME and for users of standards to find a solution? Possible approaches are to adopt the dominant standard, or to develop an umbrella standard that references other regional and national standards, or to develop a global consensus standard from scratch. ASME is involved in helping promote whichever approach best serves a specific industry and the users of the applicable ASME standards. ASME standards have changed over the last few years to include new con-struction materials, to address new topics, and to incorporate new calculation methods. As these changes continue to be introduced, globalization brings even more change, requiring greater flexibility and adaptation from industry.Elevators, Escalators, and Moving Walkwaysby Jim CoakerHow many times in the past week have you ridden in an elevator, on an esca-lator, or on a moving walk? These actions are so routine in everyday life that they happen automatically and are too numerous to recall.Behind each mechanism is a web of machinery, power sources, control sys-tems, and redundant safeguards in both design and operation that deliversafe vertical transportation without inci-dent. ASME International’s Safety Codesfor Elevators and Escalators, Inspectors’Manuals, Existing InstallationRequirements, Evacuation Guide, andElectrical Requirements are one of thelargest areas covered by the Society’s600 standards.Elevator ridership in the United States isconservatively estimated at more than200 billion passenger rides per year, a figure that makes it easy to appreciate the critical role that codes and stan-dards play in public safety. Dynamic change defines the world of technical applications and ASME’s standards are constantly updated to keep abreast of changes in technology.Starting with basic design principles relating to public safety, these codes and standards establish guidelines and requirements for equipment design, installation, operation, inspection, and maintenance. Even if the end result is invisible—a normal convenience in everyday life functioning without incident—the underlying complexities of the system present stimulation and challenge to the engineering mind. Some professionals spend their careers in this industry. The next time you ride an elevator or escalator, remember the engineers who have dedicated their careers to giving you a safe arrival!What are Performance Test Codes?by Philip M. Gerhart, Ph.D. and Sam J. Korellis, P.E.ASME Performance Test Codes (PTC) provide rules and procedures for planning, preparing, executing, and reporting performance tests. A performance test is an engineering evaluation; its results indicate how well the equipment performs its functions.Performance Test Codes originated as “Power Test Codes” and emphasized energy-conversion equipment. The first ASME Code was Rules for Conducting Boiler Tests, published in 1884. Today, nearly 50 PTCs are available; they cover individual components (steam generators, turbines, pumps, compressors), sys-tems (flue gas desulfurization, fuel cells), and complete plants (cogeneration plants). In addition to equipment codes, supplements on instruments and appa-ratus cover measurement systems (temperature, pressure, flow) and techniques (uncertainty analysis) common to several codes.For more than a century, ASME PTC tests have pro-vided results with the highest level of accuracy,based on current engineering knowledge and prac-tices, and taking into account the costs of the testsand the value of the information obtained. AllASME codes are developed using input from arange of parties, who may be interested in thecode and/or in the associated equipment orprocess. Codes have the force of a legal docu-ment when cited in contracts, as they frequently are, for determining the method by which equipment performs as guaranteed. PTCs are used by equipment owners, equipment suppliers, and test engineers. ASME PTCs protect users from poorly performing products and enable suppliers to compete fairly by offering reliable products. Purchase specifications are great-ly strengthened by citing the results of PTC tests. When buying new equipment, purchasers may specify that the equipment guarantee will be based on the results of a specific ASME PTC test. Design engineers consult PTC documentsto ensure that proper instrument connections will be available. Test engineers install the required instrumentation and use the code’s procedures and calcula-tion methods to conduct tests on the new equipment. Representatives of all par-ties to the test ensure that the test methods are in compliance with the code. Finally, the test results are compared to the performance criteria.Sometimes manufacturers and suppliers want to determine the exact perform-ance of their equipment to understand the design margins or the effects of man-ufacturing tolerances on performance. In this case, code tests are conducted outside of any performance guarantees.To ensure that ASME PTCs best serve global industries, additional products and services always are being evaluated. As the preeminent provider of standardized methods for performance testing; monitoring; and analysis of energy conversion and industrial processes, systems, and equipment, ASME continues to develop and add new codes.A Look at ASME’s Boiler and Pressure Vessel Code (BPVC)by Domenic Canonico, Ph.D.The ASME Boiler and Pressure Vessel Code (BPVC) is a standard that provides rulesfor the design, fabrication, and inspection of boilers andpressure vessels. A pressure component designedand fabricated in accordance with this standard willhave a long, useful service life, and one that ensuresthe protection of human life and property. Volunteers,who are nominated to its committees based on theirtechnical expertise and on their ability to contributeto the writing, revising, interpreting, and administeringof the document, write the BPVC.The idea for the BPVC arose in 1911 out of the need forpublic safety, following the invention of the steam engine inthe late 18th century. Throughout the 19th century there were thousands of boiler explosions in the United States and Europe, some of which resulted in many deaths.The first Boiler and Pressure Vessel Code (1914 edition) was published in 1915; it was one book, 114 pages long. Today there are 28 books, including twelve dedicated to the construction and inspection of nuclear power plant components and two Code Case books. (The 2001 edition of the Boiler and Pressure Vessel Code is more than 16,000 pages.) The 28 books are either standards that provide the rules for fabricating a component or they are support documents, such as Materials (Section II, Parts A through D), Nondestructive Examination (Section V), and Welding and Brazing Qualifications (Section IX). Code Cases provide rules that permit the use of materials and alternative methods of construction that are not covered by existing BPVC rules.The BPVC is the largest ASME standard, both in size and in the number of volunteers involved in its preparation. At any one time there are more than 800 volunteers serving on one or more committees. The fact that the BPVC is a committee organ-ized and administered by ASME may give the impression that the volunteers are all mechanical engineers. This is not the case; to write such a standard requires a breadth of knowledge that is not available in any one discipline. Volunteers on the committees have expertise in materials (metallurgical and materials engineering),structures (civil engineering), physics, chemistry (chemistry and chemical engi-neering), and other disciplines in addition to mechanical engineering.Various sections of the BPVC have been adopted into law in all the Canadian provinces and in 49 of the 50 United States. More than one-quarter of the compa-nies accredited by ASME Codes and Standards to manufacture pressure parts in accordance with various sections of the BPVC are located outside of North America.Internationally, the BPVC is recognized in more than 60 countries.The record of the BPVC is a testament to its success. The safety record of pressure-containing components manufactured in accordance with the rules of the BPVC is outstanding. The contributions made over the past 90 years by thousands of volun-teers, who have participated in the preparation of the BPVC, have made this possible.Ph ot o co ur te sy o f t he N oo te r C or po ra tio n,St . L ou is , M O.U.S. Government Use of ASME Codesand Standardsby Guy A. ArlottoYour organization wants to construct and operate a nuclear power plant; to supply the reactor steam supply system; to supply architect engineering services; or to supply components (e.g., pressure vessels, piping pumps, valves) for anuclear power plant. The U.S. NuclearRegulatory Commission (NRC), the federalagency responsible for issuing construc-tion permits and operating licenses fornuclear power plants, requires confor-mance with certain ASME codes andstandards in its regulations. Therefore,to obtain a construction permit or anoperating license, you must meet therequirements of these codes.In the 1980s the federal government’sOffice of Management and Budget (OMB)first issued OMB Circular A-119, whichrequired certain government agenciesto use applicable national consensusstandards wherever practical, in lieu ofdeveloping their own regulations to accomplish their missions. More recently, a public law (PL 104-113) mandates the use of national consensus standards, including ASME codes and standards, by federal agencies where applicable. (The Dept. of Defense, the U.S. Postal Service, and the U.S. Coast Guard routinely use them.)The U.S. Atomic Energy Commission (AEC), NRC’s predecessor, did not need the impetus of OMB A-119 or PL 104-113 to recognize the potential benefits of using ASME codes and standards to work more efficiently and to ensure public health and safety. A decade before OMB A-119 was first issued, the AEC had already endorsed certain ASME codes in its regulations. In fact, AEC involvement with the ASME codes and standards program dates from the mid-1960s, when AEC staff began working on appropriate ASME code committees. The use of nuclear power in the United States originated with the U.S. Navy program to develop it as the power source for submarines. The Navy took it further by applying it to surface ships and by demonstrating its potential for land-based electrical power generation at the nuclear power plant at Shipping Port, Pennsylvania.ASME recognized the need for enhanced codes and standards because the technology was new and had no tested codes and standards available, and because the consequences of component failures could have a serious impact on public safety. It created a committee to develop design and construction requirements to ensure the integrity, first of the reactor pressure vessel, and then of other important pressure-retaining components. This resulted in what is today called BPVC’s Section III. It covers an array of nuclear components, including pressure vessels, piping, pumps, valves, supports, core support structures, pressure relief, containment systems for spent fuel and high-level waste transport packaging, and concrete components.At the same time that Section III was being created by ASME in the late1960s and early 1970s, the AEC was receiving applications monthly from electric utilities in the United States for permits to construct nuclear power plants. It was at that time that the AEC committed resources to the ASME Codes and Standards program by supporting expert staff members to work on ASME committees developing nuclear codes. This gave the AEC the confi-dence to accept the finished code because its own staff had direct input in the development of the requirements, and it understood the contents of the code and the bases for the requirements. More important, the AEC decided to endorse portions of ASME codes in its regulations, thus making it a require-ment to satisfy the code as a condition for obtaining a construction permit. Federal (AEC/NRC) regulations require first that one obtain a construction permit allowing construction to begin. After construction is complete, the utility must apply for and receive an operating license before beginning operation. As nuclear power plants progressed from the construction phase to the oper-ating phase, ASME developed and published Section XI, Rules for Inservice Inspection of Nuclear Power Plant Components, to ensure that continued safe operation was maintained over the life of the plant. This also was endorsed in NRC regulations, making the periodic inspection and testing of components and meeting acceptance standards a requirement for maintaining a licenseto continue operation. This gives the NRC and the public a level of confidence that any degradation of the plant during the period of operation has not reduced safety below an acceptable level.The NRC’s use of ASME codes and standards benefits ASME, the NRC, and most important, the public. ASME’s codes and standards gain increased visi-bility and stature through government use, its volunteers see the fruits of their efforts, and public safety is maintained. The NRC benefits because by using ASME codes, it can be a more efficient government agency, both in its deci-sion-making and during various phases of the licensing process. The better the NRC functions, the better the health and safety of the public is protected.ASME Codes and Standards in Chinaby John FergusonFor several years The American Society of Mechanical Engineers has worked to advance the use of ASME codes and standards in China, most notably, standards for nuclear power plant equipment and for boilers and pressure vessels. Beginning in October 2000, several successful workshops were held in Beijing in cooperation with various Chinese organizations.ASME’s goals are to have China’s nuclearpower plants, facilities, and associatedequipment designed and constructed toASME codes, and to have existing facili-ties use ASME standards for operationand maintenance. Chinese engineersand regulatory personnel respect thetechnical content of these codes andstandards and, in the absence of havingtheir own technical standards, haveexpressed an interest in establishing ASME standards as the standard for their nuclear programs.In the last decade, ASME’s Boiler and Pressure Vessel Code (BPVC) has begun to get wider use in China, and the Chinese government accepts imported equipment constructed to its requirements. Greater use of the BPVC in the construction of fossil-fuel-fired power boilers and in the petroleum and chemical industries is being pursued.With the increased use of ASME codes and standards in China, U.S. manufac-turers and engineering service companies will have the opportunity to under-take jobs and participate in the current expansion and new construction taking place, particularly in the nuclear area. It also provides opportunities for the sale of U.S.-made components. By having common technical require-ments for equipment and services based on ASME codes and standards, barriers to trade are reduced and public safety is enhanced.A Global Highway for Mechanical Engineering Communications: ASME Y14.5, Dimensioningand Tolerancingby Lowell W. FosterASME Y14.5M-1994, Dimensioning and Tolerancing, which specifies engineering drawing requirements, originated in the 1950s. Over the years it has incorpo-rated technical innovations such as the new electronic compatible systems.Its original goal was to delineate and define mechanical part hardware and to create a common technical drawing language for standardized drawing prac-tices. It was also recognized that repre-senting a perfect part on the drawingmust include a permitted “tolerance”as a deviation from the perfect part(because perfection cannot be achievedin real production). This explains thedimensions and tolerances emphasisof Y14.5M. This standard is designatedas an “Internationally RecognizedStandard,” the standard of choicethroughout much of the world.ASME Y14.5M predominantly illustrates the Geometric Dimensioning and Tolerancing (GDT) language to capture the “function and relationships” of part features. This shows that the design requirements and dynamics of part fea-tures (e.g., holes, pins, slots, surfaces), as they relate in part function, fit, or assembly with mating parts, can be captured and specified with “geometric characteristics,” “datum references,” and the other tools of the system. For example, in a mating part situation where four pins on one part are to assem-ble with four mating part holes, would it not stand to reason that if a hole (any one of them and each individually) was produced away from its worst case low limit size as an individual feature (i.e., be larger within its size tolerance), that any permitted error (tolerance) of location of that hole could be increased an equal amount? In other words, size of features can have an effect on, com-pensate for, and assist in meeting the location tolerance. This is known as the “maximum material condition” principle and increases possible location toler-ances, brings down costs of production, and makes using functional gaging principles possible, which ensures assembly and other advantages. The prod-uct designer can select this option or decide on a more stringent method (called “regardless of feature size”) when this dynamic is prohibited. Othercontrols delineate part form, orientation, profile, and location of features rela-tive to design requirements. This is all done through the system’s symbolic language and the rules and guidelines provided in the standard. This useful, powerful, and widely recognized GDT language is now established as the best method for communicating design requirements. Through use of the GDT system, production, quality, inspection, tooling, programming, and all other supporting operations can meet the requirements using a greater range of methods.Cranes for Nuclear Facilitiesby James E. NelsonIt would be difficult to overstate the importance of using the safest crane design for handling heavy loads in nuclear facilities—it is critical. Dropping or losing control of a load—a dreaded scenario—could result in damage to safe-ty-critical equipment or spent fuel. It is unthinkable and it is impermissible.With this in mind, the ASME Committeeon Cranes for Nuclear Facilities (CNF) haswritten standards for overhead cranes,the equipment that handles the majorityof heavy loads.The Committee on Cranes was estab-lished in 1976, shortly after the U.S.Nuclear Regulatory Commission (NRC)first issued written guidelines for safety-critical or single-failure-proof (SFP) cranes.In 1980, the committee's scope wasbroadened from nuclear power plantsto nuclear (and other critical load han-dling) facilities. Its first standard, ASMENOG-1, Rules for Construction ofOverhead and Gantry Cranes, wasissued in 1983. The committee’s second standard, NUM-1, Rules for Construction of Cranes, Monorails, and Hoists, followed in 1996. Committee members represent a range of power plant and nuclear facility owners and operators, engineers, reg-ulatory personnel, constructors, equipment suppliers, and crane manufacturers.No other industry or government standards have addressed important issues for nuclear facility cranes such as quality assurance, dynamic seismic analy-sis, and SFP crane features. NOG-1 and NUM-1 cover all of these and more.In a Nuclear News magazine article,1NRC Commissioner Jeffrey Merrifield said, “I believe that the future of the nuclear industry does not hinge on cor-porate decisions about new plants, it hinges on the safety ofthe existing fleet of reactors,” and “Anyone who believes that safety and economic value are mutually exclusive goals is simply blind to the realities that history has unmistakably, and sometimes painfully, taught this industry.”Today, construction of new nuclear plants in the United States is being encour-aged and numerous operating plants are applying for operating life extensions.A heavy load drop would be disastrous for the industry, even without an offsite release of radioactive materials.The NRC defines a heavy load as anything weighing more than a nuclear fuel assembly (approximately one ton). A spent fuel cask can weigh 100 to 150 tons or more, and if dropped into the spent fuel pool, it could cause serious damage to the pool and/or the fuel, resulting in a radioactive release. Dropped elsewhere, it could damage safe shutdown equipment or rupture the cask itself. The empty hook block on such a crane can weigh four or five tons and can itself cause severe damage if it falls into the fuel pool or onto safety-related equipment.The NRC identified two primary causes of load drops as being severe types of overload: "two blocking" or "load hangup." Two blocking occurs when control malfunction or maintenance error permits unintentional overhoisting, resulting in solid contact between the hook block and the head block or its supporting structure. Immediate failure results with the wire rope and the dropping of the load or empty hook block.Load hangup is abrupt snagging of the moving load, resulting in similarly severe effects on the equipment. Other causes of dropped loads include "mis-reeving" of the hoist wire rope and failure of the hoisting machinery itself.The NRC guidelines for SFP cranes, as well as ASME NOG-1 "Type I" and NUM "Type I" SFP standards, specify cranes to be designed either to withstand all such incidents without damage or loss of load, or to make the likelihood of their occurrence extremely small. Type I NOG-1 and NUM-1 crane standards in particular incorporate design requirements specific to these concerns, and well beyond the requirements of other crane standards.The work of the CNF Committee of ASME and the application of its standards has never been more relevant. In the last few years there has been a tremen-dous increase in the handling of spent fuel casks to move fuel from plant fuel pools to independent spent fuel storage installations. Many operating plants have reached or are approaching the time when they must remove spent fuel from their pools in order to continue operation, but have delayed making heavy load handling (crane) decisions. Now the need is imminent. In the handling of spent fuel, both operating plants and decommissioning plants face many of the same issues.1 ”Safety: The foundation upon which economic value is built,” Nuclear News,August 2001.Codes and Standardsat a GlanceWhy are there codes and standards...?The Industrial Revolution profoundly changed the way people lived by introduc-ing machinery that transformed daily life. Farm implements no longer had to be made by hand—they could be manufactured. Affordable manufactured goods of all kinds would transform home life—textiles, dishware, reading material. A coal-burning furnace and boiler could heat the water in your home. Transportation began to move at unimagined speeds, far exceeding that of a horse. Slowly, handmade items were being replaced with manufactured items; human strength and horsepower were being replaced by machinery driven by steam power—steam engines, boilers....Because it’s a catastrophe when a screw doesn’t fit.The most serious problem facing 19th century engineers was exploding boil-ers. Heating water to produce steam and converting that steam into energy to power machinery revolutionized the production of goods. To build up pressure, steam must be contained in some type of vessel; but uncontrolled, pressur-ized steam can burst a vessel even if it’s made of steel. For want of reliably tested materials, secure fittings, and proper valves, boilers of every descrip-tion, on land and at sea, were exploding with terrifying regularity. (They would continue to do so into the 20th century.) Although engineers could take pride in America’s strides in technology, they could not ignore the 50,000 dead and 2 million injured annually by such accidents. Thus, mechanical engineers in the 1880s began seeking reliable methods for testing steam boilers.Lack of interchangeability was also becoming a problem. A consumer couldn’t buy a bolt in California and use it on a nut acquired in New Jersey because the threading didn’t match. Therefore, the farm implement, shotgun, or pipe was rendered useless, unreliable, or dangerous.When The American Society of Mechanical Engineers (ASME) was founded in 1880, discussion began immediately on establishing standards; it focused on shop drawing symbols, pulleys, line shafting, machine screws, key seats, and drawing boards. At its annual meeting in 1883, a committee on standards and gages was created and a paper was presented urging the adoption of a set of rules for conducting boiler tests that could be accepted as a standard code of practice by engineers. The paper emphasized the prevailing lack of uniformity in which “every engineer who performs a boiler test makes a rule for himself, which may be varied from time to time to suit the convenience or interests of the party for whom the test is made.”2。

在核动力装置卷册，在世界上有较高的权威，往往直接采用。

法国的 RCC-M 规范和德国的 KTA 规范也直接收入了其最重要方面,再加上本国的实践而制定的。

3.2 ASME规范的构成及与核动力装置相关的内容ASME规范是美国锅炉及压力容器方面的国家标准，共分为十一卷，内容如下：•••••ASME 锅炉压力容器规范的总目录：第 I 卷动力锅炉第 II 卷材料技术条件A 篇铁基材料(钢铁材料)•••••••••• B 篇非铁基材料(有色金属材料)•• C 篇焊条、焊丝及填从金属• 第 III 卷核动力装置••••••• NCA 分卷 -- 第一、二册的总要求••• 第一册•••••••••• NB分卷 -- 一级设备•••••••••• NC分卷 -- 二级设备•••••••••• ND分卷 -- 三级设备•••••••••• NE分卷 -- MC级设备 (适用钢制安全壳) •••••••••• NF分卷 -- 设备支承 (适用于各级别支承)•••••••••• NG分卷 -- 堆芯支承 (适用于CS级) •••••••••• 附录•••••••••• 第二册•••••••••• 混凝土反应堆容器与安全壳规则▲CB分卷----混凝土反应堆容器；▲CC分卷----混凝土安全壳。

第 IV 卷采暖锅炉第 V 卷无损检验第 VI 卷采暖锅炉维护和运行的推荐规则第 VII卷动力锅炉维护的推荐规则第VIII卷压力容器•••••• 第一册•••••• 第二册 -- 另一规则第 IX 卷焊接与钎焊评定第 X 卷玻璃纤维增强塑料压力容器•• 第 XI 卷核动力装置在役检验规则其中第Ⅲ卷是关于核动力装置设备的规范，与第Ⅲ卷相关的其它部分有：第Ⅱ卷材料技术条件；第Ⅴ卷无损检验；第Ⅸ卷焊接及钎焊评定；第Ⅺ卷核动力装置设在役检验规程。

ASME规范鼎鼎大名，是目前世界上普遍遵循的规范之一。

可以毫不夸张地说，RCCM是其衍生产品，并对其进行了部分精简，有后来居上的感觉，但是美国人也很认真，不断地进行规范的升版，丝毫不敢懈怠，因为在这个全球化的时代，谁拥有了普适的标准的所有权，谁就有话语权，由此，便形成了生产力。

下面就ASME的结构和主要内容进行介绍，以方便学习工作中使用。
