IEC 60068-2-13-2021 环境试验--第2-13部分:试验--试验M:低气压 Environmental testing – Part 2-13: Tests – Test M: Low air pressure

This part of IEC 60068 specifies methods of test applicable to specimens which, during 
transportation, storage or in service, can be subjected to low air pressure.  
The object of the low air pressure test is to determine the ability of components, equipment or 
other articles to be used, transported or stored at low air pressure. 
Components, equipment or other articles to be used, transported or stored under a 
simultaneous combination of high or low temperature and low air pressure, where the 
combination is important for the stresses imposed on the articles or for the failure mechanisms, 
are then tested in accordance with IEC 60068-2-39.dition 5.0 2021-03 INTERNATIONAL STANDARD NORME INTERNATIONALE Environmental testing – Part 2-13: Tests – Test M: Low air pressure Essais d'environnement – Partie 2-13: Essais – Essai M: Basse pression atmosphérique IEC 60068-2-13:2021-03(en-fr) THIS PUBLICATION IS COPYRIGHT PROTECTED Copyright ？ 2021 IEC, Geneva, Switzerland All rights reserved.
