DIN EN 60068-3-1:2012-04

This standard provides guidance regarding the performance of cold and dry heat tests. The following modifications have been made with respect to DIN EN 60068-3-1:2000-02: - Removal of guidance regarding thermal characteristics of chamber walls. - Revision of clause addressing environmental chambers that do not use movement of air for temperature control. Specimen performance may be influenced or limited by the temperatures in which the specimen is operated. The level of influence may be affected by test gradients that exist within the test system (test chamber) and internal temperatures within the specimen itself. In order to determine the level of influence that exists and to ensure that the specimen is designed appropriately, cold and/or dry heat tests are performed. The responsible committee is K 131 "Umgebungsbedingungen, Klassifizierung und Prüfungen" ("Environmental conditions, classification and tests") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
