IEC 60068-2-39:2015 defines environmental testing guidance for combined temperature or temperature and humidity with low air pressure conditions, helping engineers evaluate how products behave when multiple stresses occur at the same time. As a technical reference, IEC 60068-2-39:2015 is useful when a documented evaluation must reflect realistic operating or transport environments rather than a single isolated stress. It supports technical review, verification activities, and compliance workflows where environmental robustness and test consistency are part of procurement or conformity assessment decisions.

What is IEC 60068-2-39:2015?

IEC 60068-2-39:2015 is part of the IEC 60068 environmental testing series and focuses on tests and guidance for combined temperature or temperature and humidity with low air pressure. Its purpose is to help define how equipment should be assessed when altitude-like low pressure is combined with thermal or moisture-related stress. For engineering teams, it provides a structured testing reference that can support technical validation, laboratory evaluation, and compliance preparation for electrical equipment and related systems.

Applications of IEC 60068-2-39:2015

This document is commonly relevant in product qualification, reliability testing, and quality workflows for equipment that may operate or be transported under reduced air pressure and varying climatic conditions. It is often used in laboratory programs that compare results across development, pre-production, and conformity assessment stages. Organizations involved in technical documentation, procurement review, or regulatory preparation may use it to align test plans with a recognized environmental testing standard and to support consistent product evaluation.

Why is IEC 60068-2-39:2015 important?

The value of IEC 60068-2-39:2015 lies in its support for repeatable and relevant environmental test conditions when multiple stresses are present together. That matters for risk management, because combined temperature, humidity, and low pressure can reveal failure modes that single-factor tests may miss. It also improves testing consistency across laboratories, supports engineering specification review, and helps evidence-based conformity assessment. For procurement and quality assurance teams, it can strengthen technical compliance decisions by providing a clear reference for documented evaluation.
