It is identical with IEC 300-2:1995 published by the lnternational Electrotechnical Commission (IEC). This standard forms Part 1 of the BS 5760 series and supersedes BS 5760-1:1985 which is withdrawn. It introduces restructured clauses to correspond with BS 5750-14, with clauses extended to provide more detailed guidance. This Part of BS 5760 describes elements of a dependability programme and gives guidance on tasks necessary to achieve specified dependability of products. It is applicable to hardware and systems containing software products. This standard cross-references and complements BS EN ISO 9004-1:1994. This standard is a guide and the use of the verbal forms “must” and “shall” in the text does not indicate mandatory requirements. BS 5760 provides comprehensive guidance on many aspects of reliability management. Sixteen parts of this standard have been published and these may be summarized as follows: Part 0: Introductory guide to reliability. This Part provides guidance for senior management and non-specialists on the importance of reliability and explains how measures to achieve reliability should be integrated with other aspects of project management. Part 2: Guide to the assessment of reliability. This Part explains the purpose and problems of assessing reliability. A range of available assessment techniques is reviewed and the principle advantages and limitations are outlined. Sections are included on the assessment of software reliability, human reliability and one-shot devices. The extension of these techniques to the assessment of availability and to the assessment of reliability of services is considered. This use of a range of statistical distributions to analyse reliability data is described. Part 3: Guide to reliability practices : examples. This Part contains authentic practical examples illustrating the principles established in BS 5760-1 and BS 5760-2. Part 4: Guide to specification clauses relating to the achievement and development of reliability in new and existing items. This Part provides detailed guidance on the specification of reliability. Part 5: Guide to failure modes, effects, and criticality analysis (FMEA and FMECA). This Part gives guidance on the application of these techniques. Part 6: Guide to programmes for reliability growth. This Part describes procedures for exposing and removing weaknesses in hardware and software items in order to achieve acceptable reliability in a product. It explains basic concepts, management and test procedures and describes techniques for analysis and correction of failures. Part 7: Guide to fault tree analysis. This Part gives guidance on the application of fault tree analysis. This technique may be used to identify factors affecting the reliability, performance and safety characteristics of a system. Part 9: Guide to the block diagram technique. This Part describes the use of the block diagram technique for modelling and evaluating the reliability of both elementary and more complex systems. The extension of the method to calculate availability is also outlined. Part 10: Guide to reliability testing. Section 10.1: General requirements. This Section provides guidance on general principles, procedures and considerations for reliability testing in the laboratory and in the field.

This Section provides a general procedure for design of test cycles, where no applicable preferred test cycles can be found. Section 10.3: Compliance test procedures for standby-state availability. This Section provides guidance on techniques for testing the availability performance of frequently maintained items under defined conditions. Section 10.5: Compliance test plans for success ratio. This Section gives procedures for preparing and applying compliance test plans for success ratio or failure ratio. Plans are provided for three main types of test. NOTE 1Further Sections of Part 10 based on other Parts of IEC 605 and related IEC standards are planned. Part 11: Guide to the collection of reliability, maintainability, availability and maintenance support data from the field. This Part provides guidance for the collection of data relating to reliability, maintainability, availability and maintenance support performance of items operating in the field. It deals in general terms with the practical aspects of data collection and presentation and briefly explores the related topics of data analysis and presentation of results. Part 12: Guide to the presentation of reliability, maintainability and availability predictions. This Part gives guidance on the presentation of quantitative predictions of reliability, maintainability and availability. The items to be included when presenting prediction information are listed and explained with the object of facilitating comparisons between projects and reports. Part 13: Guide to preferred test conditions for equipment reliability testing. Section 13.1: Indoor portable equipment: low degree of simulation. Section 13.2: Equipment for stationary use in weather protected locations: high degree of simulation. Section 13.3: Equipment for stationary use in partially weather protected locations: low degree of simulation. Section 13.4: Equipment for portable and non-stationary use: low degree of simulation. Part 14: Guide to formal design review. This Part provides guidelines for planning and conducting design reviews. Much of the guidance given is widely applicable and relevant to the general conduct of design reviews but it also includes details of the specific contributions to be made by various specialists. Part 15: Guide to the application of Markov techniques. This Part provides guidance on the application of Markov techniques to dependability analysis. Further information, including advice on the application, benefits and limitations of Markov techniques, is given in section 11 of BS 5760-2. Part 17: Reliability growth Statistical test and estimation methods. This Part describes the power law reliability growth model and related projection models. It provides procedures to estimate some or all of the quantities listed in clause 9 of BS 5760-6:1991. Further Parts of BS 5760 are envisaged in order to provide guidance on other techniques of reliability management (see note 4). Whilst mainly addressing system and equipment level reliability, many of the techniques described in the Parts of BS 5760 may also be applied at the component level. Further guidance on component reliability is given in CECC 00804. Guidance on specific aspects of maintainability is provided in the various Parts of BS 6548 Maintainability of equipment.

It is essential that these definitions and concepts should be fully understood if this guide is to be interpreted correctly. For this reason it is recommended that BS 5760-1 should be read in conjunction with BS 4778. NOTE 3BS 4778-3.2 deprecates the use of the terms “failure modes and effects analysis” and “failure modes, effects and criticality analysis” It favours the use of “fault modes and effects analysis” and “fault modes, effects and criticality analysis”, and these terms are used throughout BS 5760-2. However, the older terms have been retained in BS 5760-5 in order to align it with the current versions of IEC 812.
