Reliability Standards

Reliability and dependability standards provide quick guides for reliability details. They

are an efficient method for avoiding the not invented here (NIH) syndrome. A wide

variety of subjects are available from IEC (International Electrical Congress) TC-56

subcommittee for publications (Technical Committee 56 is responsible for dependability

issues driven by a strategic policy statement).

IEC defines dependability as- “Dependability describes the availability performance and

its influencing factors: reliability performance, maintainability performance and

maintenance support performance”. The committee was formed in 1965 as TC 56

Reliability and Maintainability and the title was changed to Dependability in 1989 and in

1990 it was agreed that the scope should no longer be limited to the electrotechnical field

but should address generic dependability issues across all disciplines. TC 56 is

attempting to minimize standards and duplication by cross-committee membership with

organizations such as IEEE and ASQ. Some of the 50 IEC publications are: • Analytical techniques • Reliability stress screening

• Collection and presentation of dependability data • Reliability testing and statistical

principles

• Dependability management • Risk analysis

• Design review • Risk management

• Integrated logistic support • Sampling and inspection procedures

• Life cycle costs • Software aspects of dependability

• Maintenance and maintenance

support • Specifications

• Miscellaneous • Weibull Analysis

• Prediction •

• Reliability centered maintenance •

• Reliability growth (Crow/AMSAA) •

Dependability management:

IEC 60300-1 (2003-06) Dependability management-Part 1 (17 pages, ~US$52)

Dependability management systems. Deals with dependability performance

issues including availability performance, reliability performance, maintainability

performance, and maintenance support performance.

IEC 60300-2 (2004-03) Dependability management-Part 2 (103 pages, ~US$92)

Provides guidelines for dependability management of product design, development, evaluation and process enhancements. Life cycle models are used to

describe product development or project phases. Applicable for detailed planning and

implementation of a dependability program to meet specific product needs.

IEC 60300-3-1 (2003-01) Dependability management-Part 3-1 (59 pages, ~US$117)

Application guide-Analysis techniques for dependability-Guide on methodology.

Describes a general overview of common dependability analysis techniques along with

advantages/disadvantages for choosing the appropriate method.

IEC 60300-3-2 (2004-11-10) Dependability management-Part 3 (79 pages, US$114)

Application guide-Section 2: Collection of dependability data from the field.

Describes guidelines for the collection of data relating to reliability, maintainability,

availability, and maintenance support performance in the field.

IEC 60300-3-3 (2005-08-29) Dependability management-Part 3 (127 pages,

~US$147)

Application guide-Section 3: Life cycle costing. This part of IEC 60300 provides

a general introduction to the concept of life cycle costing and covers all applications.

This standard is intended for general application by both customers (users) and suppliers

of products. It explains the purpose and value of life cycle costing and outlines the

general approaches involved. It also identifies typical life cycle cost elements to facilitate

project and programme planning.

IEC 60300-3-4 (2007-09) Dependability management-Part 3-4 (71 pages, ~US$120)

Guide to the specification of dependability requirements.

IEC 60300-3-5 (2001-03) Dependability management-Part 3-5 (139 pages, ~US$137)

Application guide-Reliability test conditions and statistical test principles.

Describes guidelines for planning and performing reliability tests and the use of statistical

methods to discover weaknesses in the design that could be corrected to improve

performance, quality, safety, robustness, reliability, availability, and reduce costs.

IEC 60300-3-6 (1997-11) Dependability management-Part 3 (59 pages, ~US$73)

Application guide-Section 6: Software aspects of dependability. Describes

dependability elements and tasks for systems or products containing software. —This

document has been withdrawn in 2004 and replaced by IEC 60300-2 .

IEC 60300-3-7 (1999-05) Dependability management-Part 3-7 (69 pages, ~US$82)

Teachers

Effective teachers model and apply the ISTE Standards for Students (Standards•S) as they design,

implement, and assess learning experiences to engage students and improve learning; enrich

professional practice; and provide positive models for students, colleagues, and the community. All

teachers should meet the following standards and performance indicators.

Reliability testing is an essential part of the

injection molding process for plastic components. It helps

to ensure that the products meet the required quality

standards and can perform reliably under different

operating conditions. In this article, I will outline a

plan for conducting reliability testing for injection

molded parts.

Firstly, it is important to identify the specific

reliability requirements for the injection molded parts.

This can be done by analyzing the intended use of the parts

and considering factors such as expected lifespan,

environmental conditions, and performance expectations. For

example, if the injection molded parts are used in

automotive applications, they may need to withstand high

temperatures and mechanical stress.

Once the reliability requirements are defined, the next
