IEC 60068-3-5:2018 is now available as \/2 which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 60068-3-5:2018 provides a uniform and reproducible method of confirming that temperature test chambers, without specimens, conform to the requirements specified in climatic test procedures of IEC 60068-2 (all parts) and other standards. This document is intended for users when conducting regular chamber performance monitoring. This second edition cancels and replaces the first edition published in 2001. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: – Confirmation procedures are clarified.<\/p>\n
