TS EN IEC 62506

TS EN IEC 62506 is a methods standard for accelerated testing of products. Its focus is how to obtain reliability and availability information in less time, while also helping reveal design weaknesses or weaknesses introduced during manufacture. In general technical terms, accelerated testing increases stress, cycling, loading, or environmental severity so that failure behaviour that would otherwise take a long time to appear can be observed sooner.

What accelerated testing is used for

The document provides guidance on applying different accelerated test techniques for measuring or improving item reliability. In the broader engineering context, accelerated tests are used to shorten the time needed to study failure modes, compare design alternatives, or support reliability growth activities. They are especially useful where waiting for failures under normal service conditions would be impractical or too slow for development, qualification, or production decisions.

Methods and boundaries covered by the document

This standard addresses accelerated testing of both nonrepairable and repairable systems. It can be used for probability ratio sequential tests, fixed-duration tests, and reliability improvement or growth tests, where the reliability measure may differ from the standard probability of failure occurrence. It also extends to accelerated testing or production screening methods intended to identify weaknesses introduced by manufacturing error. Services and people are explicitly outside its scope.

• Different test strategies may be chosen depending on the reliability question being asked
• Accelerated conditions are used to expose likely failure modes sooner than normal use would allow
• Production screening can be used to detect defects introduced during manufacture
• The standard is concerned with technical items and systems, not with services or human subjects
