CSA ISO/IEC TR 15942:04 (R2019)

CSA Preface Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the Canadian Advisory Committee (CAC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T). This Technical Report was reviewed by the CSA TCIT under the jurisdiction of the Strategic Steering Committee on Information Technology and deemed acceptable for use in Canada. (A committee membership list is available on request from the CSA Project Manager.) From time to time, ISO/IEC may publish addenda, corrigenda, etc. The CSA TCIT will review these documents for approval and publication. For a listing, refer to the CSA Information Products catalogue or CSA Info Update or contact a CSA Sales representative. This Standard has been formally approved as a National Standard of Canada by the Standards Council of Canada. Scope This Technical Report provides guidance on the use of Ada when producing high integrity systems. In producing such applications it is usually the case that adherence to guidelines or standards has to be demonstrated to independent bodies. These guidelines or standards vary according to the application area, industrial sector or nature of the risk involved. For safety applications, the international generic standard is [IEC 61508] of which part 3 is concerned with software. For security systems, the multi-national generic assessment guide is [ISO CD 15408]. For sector-specific guidance and standards there are: - Airborne civil avionics: [DO-178B] - Nuclear power plants: [IEC 880] - Medical systems: [IEC 601-4] - Pharmaceutical: [GAMP] For national/regional guidance and standards there are the following: - UK Defence: [DS 00-55] - European rail: [EN 50128] - European security: [ITSEC] - US nuclear: [NRC] - UK automotive: [MISRA] - US medical: [FDA] - US space: [NASA] The above standards and guides are referred to as Standards in this Technical Report. The above list is not exhaustive but indicative of the type of Standard to which this Technical Report provides guidance. The specific Standards above are not addressed individually but this Technical Report is synthesized from an analysis of their requirements and recommendations.
