As a liquid bath medium,water and oil have been found satisfactory and controllable at the specified test temperature. Solid block baths shall meet the same temperature control and immersion conditions and shall be checked for temperature measurement(heat transfer)for each product class by running tests on tubesfilled with30mL of product plus a metal strip of the nominal dimensions given,plus a temperature sensor. 5.4Temperature Sensing Device(TSD),capable of monitor-ing the desired test temperature in the bath to within an accuracy of61°C or better.The ASTM12C(12F)(see Specification E1)or IP64C(64F)total immersion thermom-eters have been found suitable to use in the test.If used,no more than10-mm(0.4-in.)of the mercury should extend above the surface of the bath at the test temperature.5.5Polishing Vise,for holding the copper stripfirmly without marring the edges while polishing.Any convenient type of holder(see Appendix X1)may be used provided that the strip is held tightly and that the surface of the strip being polished is supported above the surface of the holder.5.6Viewing Test Tubes,flat glass test tubes,are convenient for protecting corroded copper strips for close inspection or storage(see Appendix X1for the description of aflat-glass Key:1Lifting eye2Wide groove for pressure relief3Knurled cap4Twelve threads per inch NF thread or equivalent5Camber inside cap to protect“O”ring when closing pressure vessel6Synthetic rubber“O”ring without free sulfur7Seamless tubeMaterial:stainless steelWelded constructionMaximum test gage pressure:700kPaN OTE1—Dimensions in millimetres.N OTE2—All dimensions without tolerance limits are nominal values.FIG.1Pressure Vessel for Copper Strip CorrosionTestviewing tube).The viewing test tube shall be of such dimen-sions as to allow the introduction of a copper strip(see6.3)and made of glass free of striae or similar defects.5.7Forceps,with either stainless steel or polytetrafluoroet-hylene(PTFE)tips,for use in handling the copper strips,have been found suitable to use.5.8Timing Device,electronic or manual,capable of accu-rately measuring the test duration within the allowable toler-ance.6.Reagents and Materials6.1Wash Solvent—Any volatile,less than5mg/kg sulfur hydrocarbon solvent may be used provided that it shows no tarnish at all when tested for3h at50°C(122°F).2,2,4-trimethylpentane(isooctane)of minimum99.75%purity is the referee solvent and should be used in case of dispute. (Warning—extremelyflammable,see A2.1.)6.2Surface Preparation/Polishing Materials,00grade or finer steel wool or silicon carbide grit paper or cloth of varying degrees offineness including65-µm(240-grit)grade;also a supply of105-µm(150-mesh)size silicon carbide grain or powder and absorbent cotton(cotton wool).A commercial grade is suitable,but pharmaceutical grade is most commonly available and is acceptable.6.3Copper Strips Specification—Use strips approximately 12.5-mm(1⁄2-in.)wide,1.5to3.0-mm(1⁄16to1⁄8-in.)thick,cut approximately75-mm(3-in.)long from smooth-surfaced, hard-temper,cold-finished copper of99.9+%purity;electrical bus bar stock is generally suitable(see Annex A1).The strips may be used repeatedly but should be discarded when the strip’s surface shows pitting or deep scratches that cannot be removed by the specified polishing procedure,or when the surface becomes deformed.6.4Ashless Filter Paper or Disposable Gloves,for use in protecting the copper strip from coming in contact with the individual duringfinal polishing.7.ASTM Copper Strip Corrosion Standards37.1These consist of reproductions in color of typical test strips representing increasing degrees of tarnish and corrosion, the reproductions being encased for protection in plastic and made up in the form of a plaque.7.1.1Keep the plastic-encased ASTM Copper Strip Corro-sion Standards protected from light to avoid the possibility of fading.Inspect for fading by comparing two different plaques, one of which has been carefully protected from light(for example,new plaque).Observe both sets in diffused daylight (or equivalent)first from a point directly above and then from an angle of45°.If any evidence of fading is observed, particularly at the left-hand end of the plaque,it is suggested that the one that is the more faded with respect to the other be discarded.7.1.1.1Alternatively,place a suitably sized opaque strip(for example,20-mm(3⁄4-in.)black electrical tape)across the top of the colored portion of the plaque when initially purchased.At intervals remove the opaque strip and observe.When there is any evidence of fading of the exposed portion,the standards shall be replaced.7.1.1.2These plaques are full-color reproductions of typical strips.They have been printed on aluminum sheets by a4-color process and are encased in plastic for protection.Directions for their use are given on the reverse side of each plaque.7.1.2If the surface of the plastic cover shows excessive scratching,it is suggested that the plaque be replaced.8.Samples8.1In accordance with D4057or D4177,or both,it is particularly important that all types of fuel samples,that pass a low-tarnish strip classification,be collected in clean,dark glass bottles,plastic bottles,or other suitable containers that will not affect the corrosive properties of the fuel.Avoid the use of tin plate containers for collection of samples,since experience has shown that they may contribute to the corrosiveness of the sample.8.2Fill the containers as completely as possible and close them immediately after taking the sample.Adequate headspace in the container is necessary to provide room for possible thermal expansion during transport.It is recommended that volatile samples befilled between70and80%of the contain-er’s capacity.Take care during sampling to protect the samples from exposure to direct sunlight or even diffused daylight. Carry out the test as soon as possible after receipt in the laboratory and immediately after opening the container.8.3If suspended water(that is,haze)is observed in the sample,dry byfiltering a sufficient volume of sample through a medium rapid qualitativefilter,into the prescribed clean,dry test tube.Carry out this operation in a darkened room or undera light-protected shield.8.3.1Contact of the copper strip with water before,during or after completion of the test run will cause staining,making it difficult to evaluate the strips.9.Preparation of Test Strips9.1Surface Preparation—Remove all surface blemishes from all six sides of the strip obtained from a previous analysis (see Note1).One way to accomplish this is to use00grade or finer steel wool or silicon carbide paper or cloth of such degrees offineness as are needed to accomplish the desired results efficiently.Finish with65-µm(240-grit)silicon carbide paper or cloth,removing all marks that may have been made by other grades of paper used previously.Ensure the prepared copper strip is protected from oxidation prior tofinal prepara-tion,such as by immersing the strip in wash solvent from which it can be withdrawn immediately forfinal preparation (polishing)or in which it can be stored for future use.N OTE1—Onlyfinal preparation(9.2)is necessary for commercially purchased pre-polished strips.9.1.1As a practical manual procedure for surface prepara-tion,place a sheet of silicon carbide paper or cloth on aflat surface and moisten it with kerosine or wash solvent.Rub the strip against the silicon carbide paper or cloth with a circular motion,protecting the strip from contact with thefingers by using ashlessfilter paper or wearing disposable gloves.Alter-natively,the surface of the strip can be prepared by use of motor-driven machines using appropriate grades of dry paper orcloth.9.2Final Preparation—For strips prepared in9.1or new strips being used for thefirst time,remove a strip from its protected location,such as by removing it from the wash solvent.To prevent possible surface contamination duringfinal preparation,do not allowfingers to come in direct contact with the copper strips,such as by wearing disposable gloves or holding the strips in thefingers protected with ashlessfilter paper.Polishfirst the ends and then the sides with the105-mm (150-mesh)silicon carbide grains picked up with a pad of cotton(cotton wool)moistened with wash solvent.Wipe vigorously with fresh pads of cotton(cotton wool)and subse-quently handle without touching the surface of the strip with thefingers.Forceps have been found suitable to use.Clamp in a vise and polish the main surfaces with silicon-carbide grains on absorbent cotton.Do not polish in a circular motion.Rub in the direction of the long axis of the strip,carrying the stroke beyond the end of the strip before reversing the direction. Clean all metal dust from the strip by rubbing vigorously with clean pads of absorbent cotton until a fresh pad remains unsoiled.When the strip is clean,immediately immerse it in the prepared sample.9.2.1It is important to polish the whole surface of the strip uniformly to obtain a uniformly stained strip.If the edges show wear(surface elliptical),they will likely show more corrosion than the center.The use of a vise(see Appendix X1)will facilitate uniform polishing.9.2.2It is important to follow the order of preparation with the correctly sized silicon carbide material as described in9.1 and9.2.Thefinal preparation is with105-µm silicon carbide powder.This is a larger grain size than the65-µm paper used in the surface preparation stage.The reason for this use of larger silicon carbide grains in thefinal preparation is to produce asperities(controlled roughness)on the surface of the copper,which act as sites for the initiation of corrosion reactions.10.Procedure10.1General—There are a variety of test conditions,which are broadly specific to given classes of product but,within certain classes,more than one set of test conditions of time or temperature,or both,may apply.In general,aviation gasoline shall be tested in a pressure vessel at100°C and other high vapor pressure fuels,like natural gasoline,at40°C.Other liquid products shall be tested in a test tube at50°C,100°C or even higher temperatures.The conditions of time and tempera-ture given below are commonly used and are quoted in the ASTM specifications for these products where such specifica-tions exist.They are,however,guides only.Other conditions can also be used when required by specifications or by agreement between parties.The test conditions of time and temperature shall be recorded as part of the result(see12.1).10.2Pressure Vessel Procedure—For use with aviation gasoline and higher vapor pressure samples.10.2.1For Aviation Gasoline and Aviation Turbine Fuel—Place30mL of sample,completely clear and free of any suspended or entrained water(see8.3)into a chemically clean and dry25-mm by150-mm test tube.Within1min after completing thefinal preparation(polishing),slide the copper strip into the sample tube.Place the sample tube into the pressure vessel(Fig.1)and screw the lid on tightly.If more than one sample is to be analyzed at essentially the same time, it is permissible to prepare each pressure vessel in the batch before completely immersing each pressure vessel in the liquid bath at10061°C(21262°F),provided the elapsed time between thefirst and last samples is kept to a minimum.After 2h65min in the bath,withdraw the pressure vessel and immerse for a few minutes in cool water(tap water).Open the pressure vessel,withdraw the test tube and examine the strip as described in10.4.10.2.2For Natural Gasoline—Carry out the test exactly as described in10.2.1but at40°C(104°F)and for3h65min.10.3Test Tube Procedure—For use with most liquid prod-ucts.10.3.1For Diesel Fuel,Fuel Oil,Automotive Gasoline—Place30mL of sample,completely clear and free of any suspended or entrained water(see8.3),into a chemically clean, dry25-mm by150-mm test tube and,within1min after completing thefinal preparation(polishing),slide the copper strip into the sample tube.If more than one sample is to be analyzed at essentially the same time,it is permissible to prepare each sample in the batch by stoppering each tube with a vented stopper,such as a vented cork before placing each tube in a bath maintained at5061°C(12262°F),provided the elapsed time between thefirst and last sample prepared is kept to a minimum.Protect the contents of the test tube from strong light during the test.After3h65min in the bath, examine the strip as described in10.4.For tests on fuel oil and diesel fuel,to specifications other than Specifications D396 and D975,a temperature of100°C(212°F)for3h is often used as an alternative set of conditions.Some automotive gasolines with vapor pressure above80kPa at37.8°C have exhibited evaporation losses in excess of10%of their volume. If such evaporation losses are apparent,it is recommended that the Pressure Vessel Procedure(see10.2)be used.10.3.2For Cleaners(Stoddard)Solvent and Kerosine—Carry out the test exactly as described in10.3.1but at1006 1°C(21262°F).10.3.3For Lubricating Oil—Carry out the test exactly as described in10.3.1,but the tests can be carried out for varying times and at elevated temperatures other than100°C(212°F). For the sake of uniformity,it is suggested that even increments of5°C,beginning with150°C,be used.10.4Strip Examination:10.4.1Empty the contents of the test tube into a suitably sized receiver.If a receiver made out of glass is used,such as a150-mL tall-form beaker,let the strip slide in gently so as to avoid breaking the glass.Immediately withdraw the strip with forceps and immerse in wash solvent.Withdraw the strip at once,dry and inspect for evidence of tarnishing or corrosion by comparison with the Copper Strip Corrosion Standards.The step of drying the strip may be done by blotting withfilter paper,air drying,or by other suitable means.Hold both the test strip and the standard strip plaque in such a manner that light reflected from them at an angle of approximately45°will be observed.10.4.2In handling the test strip during the inspection and comparison,the danger of marking or staining can beavoidedif it is inserted in a flat glass tube (see Appendix X1),which can be stoppered with absorbent cotton.11.Interpretation of Results11.1Interpret the corrosiveness of the sample in accordance with one of the classifications of the ASTM Copper Strip Corrosion Standard as listed in Table 1.11.1.1When a strip is in the obvious transition state between that indicated by any two adjacent standard strips,rate the sample at the more tarnished classification.Should a strip appear to have a darker orange color than Standard Strip 1b,consider the observed strip as still belonging in Classification 1;however,if any evidence of red color is observed,the observed strip belongs in Classification 2.11.1.2A 2a strip can be mistaken for a 3a strip if the brassy underlay of the 3a strip is completely masked by a magenta overtone.To distinguish,immerse the strip in wash solvent;a 2a strip will appear as a 1b strip,while a 3a strip will not change.11.1.3To distinguish a 2c strip from a 3b strip,place a test strip in a 25-mm by 150-mm test tube and bring to a temperature of 340630°C in 4to 6min with the tube lying on a hot plate.Adjust to temperature by observing a high distillation thermometer inserted into a second test tube.Thus,a 2c strip will assume the color of a 2d strip and successive stages of tarnish;a 3b strip will take on the appearance of a 4a strip.11.1.4Repeat the test if blemishes due to fingerprints are observed,or due to spots from any particles or water droplets that may have touched the test strip during the digestion period.11.1.5Repeat the test also if the sharp edges along the flat faces of the strip appear to be in a classification higher than the greater portion of the strip;in this case,it is likely that the edges were burnished during preparation (polishing).12.Report12.1Report the corrosiveness in accordance with one of the classifications listed in Table 1.State the duration of the test and the test temperature in the following format:Corrosion copper strip ~X h /Y °C !,Classification Zpwhere:X =test duration,in hours,Y =test temperature,°C,Z =classification category (that is,1,2,3,or 4),and p =classification description for the corresponding Z (forexample,a,b).13.Precision and Bias13.1In the case

石油产品铜片腐蚀的试验方法（GB/T5096）北京时代新维测控设备有限公司生产的TP582铜片腐蚀测定仪是依据GB/T5096研制，适用于测定航空汽油，喷气燃料，车用汽油，天然气有或具有雷德蒸气压不大于124千帕斯卡（930mm汞柱）的其他烃类，溶剂油，柴油，馏分燃料油，润滑油和其他石油产品对铜片腐蚀的程度。

为什么要测量石油产品中的铜片腐蚀呢？因为原油是含酸的，所以绝大多数从原油生产出来的产品都有一定的酸性（腐蚀性），铜片腐蚀就是测量石油产品的腐蚀性；不同指标的用于不同级别的终端，例如：液化气中的腐蚀性，对钢材设备有微量的腐蚀性，对橡胶有溶化作用，灌装液化气终端都有塑料管，腐蚀性大，肯定会产生危险。

下面具体介绍下铜片腐蚀测定仪的试验方法：铜片腐蚀设备用于测定柴油、汽油、润滑油或其他石油产品对铜的腐蚀性程度,本方法涉及到易燃材料,操作前要注意试样的燃点、闪点,操作时要注意安全. 铜片的准备：1、用夹具纵向夹紧铜片，先用比较粗的砂纸（目数越低砂纸越粗）把铜片的瑕疵去掉，可来回调换夹具上铜片的方向，使铜片的六个面上所有部位上的瑕疵和以前打磨的痕迹都去掉，打磨完后可以用定量的滤纸擦去铜片上的金属屑，此时可以把铜片放入洗涤溶剂中清洗后擦干再进行最后磨光，也可以直接进行最后磨光，打磨的铜片均要拿镊子或滤纸来拿，不可以用手触摸。

2、用目数较高的砂纸打磨铜片或用蘸了砂粒的脱脂棉打磨铜的表面，磨时尽量沿铜片的长轴方向打磨。

3、在铜片打磨光亮后用脱脂棉擦去金属屑，铜片擦干净后放入准备好的试样中。

试验过程:1、取样：取30 毫升的试样倒入试验试管中，试样尽量保存在干净、深色的玻璃瓶内，试管要干燥、清洁。

2、不同的试样采用不同的试验步骤：A、润滑油、溶剂油、煤油:量取30 毫升完全清澈、无悬浮水或内含水的试样倒入清洁、干燥并带有试管夹的试管中，将最后磨光、干净的铜片放入该试管的试样中，把带有试管夹的试管放到已维持在100±1℃的浴中，在浴中放置3±5 小时后取出试管，检查铜片。

油品腐蚀测定实验报告1. 实验目的本实验旨在通过对不同油品的腐蚀性进行测定，评估其对金属材料的腐蚀程度，为油品的选择和使用提供参考依据。

2. 实验原理腐蚀是指金属在与其周围介质接触时，由于电化学反应而产生的一种化学变化。

油品作为一种常见的润滑材料和润滑介质，在与金属发生接触时，也会产生腐蚀现象。

本实验采用重量损失法来评估油品对金属材料的腐蚀性。

具体步骤如下：1. 清洗金属试样，使其表面干净、无杂质。

2. 将未知油品样品与金属试样接触一段时间。

3. 取出金属试样，用乾燥纸巾将其表面上的油品擦净。

4. 用精密天平称量金属试样的质量。

5. 将金属试样放入烘箱中加热干燥，直至试样的质量不再发生变化。

6. 计算金属试样的质量损失，作为油品对金属的腐蚀程度的评估指标。

3. 实验材料和设备- 金属试样（不同种类和规格）- 未知油品样品- 乾燥纸巾- 精密天平- 烘箱4. 实验步骤1. 将金属试样放入洗涤剂中浸泡10分钟，用流动水冲洗干净。

2. 用无水酒精擦拭金属试样表面，保证其干净无杂质。

3. 将试管中的未知油品样品倒入培养皿中。

4. 将金属试样放入培养皿中，与油品样品接触3小时。

5. 取出金属试样，用乾燥纸巾将其表面上的油品擦净。

6. 用精密天平称量金属试样的质量，并记录下来。

7. 将金属试样放入烘箱中加热干燥，直至试样的质量不再发生变化，再次称量并记录质量。

8. 计算金属试样的质量损失，作为油品对金属的腐蚀程度的评估指标。

5. 实验结果与分析在本次实验中，我们使用了三种不同的油品样品A、B和C，分别与金属试样接触3小时后进行测量和比较。

实验结果如下表所示：油品样品金属试样质量损失（g）A 0.02B 0.05C 0.08通过测量结果可以看出，油品样品C对金属试样的腐蚀程度最大，而油品样品A 的腐蚀性最小。

这说明油品样品C可能含有一些腐蚀性物质，而油品样品A中这些物质的含量较低。

根据这些数据，我们可以给出油品样品的腐蚀性评估，提供选择和使用油品的参考依据。
