PREFACE

This glossary is compiled by direction of the Group of National Directors for Quality Assurance in accordance with Part 1 of AAP-6 NATO Glossary of Terms & Definitions - Policy & Procedures for the NATO Terminology Standardisation Programme. This glossary is not exhaustive. It is not designed to compete with any existing Reliability and Maintainability (R&M) glossary of terms, as it is only relevant to terms included in Allied Reliability and Maintainability Publications (ARMPs) which are not explicitly defined in those documents. In addition, where the terms in this glossary differ from NATO-agreed terms, they are to be considered for ARMP use only. Its purpose is to explain specialist terms in the ARMPs, thereby promoting mutual understanding.

The use of ISO 8402-1994 and IEC-50(191) terms has been approved by the appropriate organisations.

This glossary is intended for incorporation, by reference, into contracts.

The glossary is published in the two official languages of NATO: English and French.

The Concise Oxford Dictionary (New Edition) is the reference source for English in ARMP-7. Le Petit Robert, Dictionnaire alphabétique et analogique de la langue français (New Edition) is the reference source for French in ARMP-7.

The source of the definition is indicated by enclosing the short title of the source in parentheses, following the definition, e.g. Reliability/Fiabilité. The ability of an item to perform a required function under stated conditions for a specified period of time (AAP-6). Where a term, used in a definition, is defined elsewhere in ARMP-7, then the term is highlighted in bold type. The detailed titles of the sources quoted in this publication are compiled at Annex A.

Proposals for new terms and definitions or changes to or deletion of existing terms and definitions are to be made in accordance with paragraph 5 Part 1 of AAP-6(V).
