DD IEC/TS 62500:2008 Process management for avionics. Defining and performing highly accelerated tests in aerospace systems. Application guide
In an increasingly harsh economic context (tighter performance requirements, shorter development cycles, reduced cost of ownership, etc.), it is essential to ensure product maturity rapidly and, in any case, by the time of commissioning.
DD IEC/TS 62500 specifies the targets assigned to highly accelerated tests, their basic principles, their scope of application and their implementation procedures. It is primarily intended for programme managers, designers, test managers, and RAMS experts to facilitate the draft of the specification and execution of highly accelerated tests. DD IEC/TS 62500 applies to all programmes and is of primary interest to the industrial firms in charge of designing, developing and producing equipment built for these programmes, and also their customers who, in drafting contractual clauses, may require that their suppliers implement highly accelerated tests.
