Describes implementation of a maintainability program. Point estimates, confidence intervals, prediction intervals and tolerance intervals. Standards Subscriptions from ANSI 600605 a money-saving, multi-user solution for accessing standards.

Describes the concept of maintainability, the general approach for maintainability, and gives maintainability objectives. Describes the tasks required for planning of maintenance and maintenance support—also describes the interface between reliability, maintainability and maintenance support planning. Deals with dependability performance issues including availability performance, reliability performance, maintainability performance, and maintenance support performance.

As the voice of the U. Please first log in with a verified email before subscribing to alerts. Describes guidelines for selecting and implementing risk analysis techniques for quality and consistency in planning and execution for risk analysis. Endurance testing, Statistical methods of analysis, Confidence intervals, Estimation, Exponential distribution, Electrical testing, Reliability, Statistical tolerance intervals, Statistical testing, Performance.

The major technical changes with respect to the previous edition 66005 the inclusion of corrected formulae for tests previously included in a corrigendum, and the addition of new methods for the analysis of multiple items.

Statistical procedures for exponential distribution — Point estimates, confidence intervals, prediction intervals and tolerance intervals. The following main categories of data are to be collected: Describes development of a preventive maintenance program using RCM techniques. Methods of evaluating the performance of intelligent valve positioners with pneumatic outputs which specifies design reviews and tests intended to measure the valve characteristics.


This part of IEC provides a general procedure for design of test cycles, where no applicable preferred test cycles can be found in IEC Application guide- Reliability stress screening of electronic hardware. We have no amendments or corrections for this standard. PERD publications are available for sale and download. Describes tests for portable equipment operated ief a stationary position.

Tests for the validity of the constant failure rate or constant failure intensity assumptions. Tests which include cycles designed according to this standard are not intended to replace ordinary tests such as qualification tests, functional pe rformance tests and environmental tests.

Essai de fiabilite des equipements. Testability and diagnostic testing. The basis of the decision as to whether to include pre-exposure tests is outside the scope of this standard. In addition the algorithms for designing test plans using a spreadsheet program are also given, together with guidance on how to choose test plans. Indoor portable equipment-Low degree of simulation. This website is best viewed with browser version of up to Microsoft Internet Explorer 8 or Firefox 3. Describes processes which are applicable for hardware items which have unacceptably low reliability in the early failure periods and when other methods such as reliability grow plots are not applicable.

Need more than one copy? These procedures are applicable whenever it is necessary to verify these assumptions.

Verification and collection, analysis and presentation of data. This standard has been withdrawn. This may be due to a requirement or for the purpose of assessing the behaviour in time of the failure rate or the failure intensity. Preferred test conditions — Section 3: Maintenance and maintenance support planning.


You may experience issues viewing this site in Internet Explorer 9, 10 or Describes the use of failure rate data for reliability prediction of components in electronic equipment including the effects of complexity, stress models for conversion. Describes direct current dc powered mobile equipment tests as give 60650 IEC Already Subscribed to this document. Statistical procedures for exponential distribution. This standard provides guidance for the collection and presentation of data relating to the reliability of electronic components and their reliability characteristics.

The failure modes defined in ISO Describes maintainability requirements ice related design 60650 use parameter, and discusses some activities necessary to achieve the required maintainability characteristics and 60065 relationship to planning of maintenance. Equipment reliability testing – Part 2: Subscription pricing is determined by: Characteristics and design of machines, apparatus, equipment Including reliability, dependability, maintainability, durability, etc.

BS IEC 60605-4:2001

Point estimates, confidence intervals, prediction intervals and tolerance intervals Status: Describes techniques covering quantitative aspects of maintainability. Describes procedures for modeling system reliability to calculate reliability and availability measures and contains a standard set of symbols related to reliability parameters.

It described the general approach in reaching these objectives and shows ho maintainability characteristics kec be specified in a requirements document or contract.
