TS IEC 60319

TS IEC 60319 is a guidance standard on how reliability data for electronic components should be collected and presented, and on how users should specify their reliability requirements to manufacturers. Its focus is the organisation of factual information needed to understand a component’s reliability characteristics, treating failure data and non-failure operating data as equally relevant forms of evidence for technical assessment.

In general technical practice, reliability data help designers anticipate how a component, circuit or system is likely to behave over time and under defined conditions. Such data are typically derived from laboratory testing, field experience, or statistical evaluation, and they support comparisons of life, failure behaviour, durability and sensitivity to operating conditions. This standard is not about setting a performance limit for a particular component type; rather, it provides a framework for defining and communicating reliability information in a consistent way.

How reliability information is exchanged between users and manufacturers

A key value of this standard is that it makes reliability requirements easier to express in technical specification language, not just as test outcomes. Component users can indicate what reliability information they need, while manufacturers can present data in a form that is more consistent and comparable. That supports component selection, system-level reliability assessment and design verification. In broader engineering terms, the standard helps align different kinds of reliability evidence so they can be interpreted together rather than in isolation.
