scope:

This document specifies a uniform and reproducible method of confirming that temperature test chambers meet the requirements specified in thermal stress test procedures.

This publication is intended for users when conducting one of the following procedures: monitoring (in situ and non in situ), characterization (e.g., for evaluation, release/acceptance and during development as well as for test set up).

The document is applicable to the following type of equipment:

temperature cycle chamber single zone,

temperature cycle chamber dual zone,

fixed convection oven with or without bias,

 fixed freezer, belt reflow ovens (used for preconditioning).

Hot-plate systems and temperature-humidity chambers or HAST chambers are not covered by this document. Some remarks may highlight the differences or challenges associated with these systems.
