IEC 60068的本部分规定了适用于以下试样的试验方法: 运输、储存或使用中可能会受到低气压的影响。 低气压试验的目的是确定部件、设备或其他物品在低气压下使用、运输或储存的能力。 在高温或低温和低气压的同时组合下使用、运输或储存的部件、设备或其他物品，如果组合对施加在物品上的应力或失效机制很重要，则应根据IEC 60068进行测试- 2-39.购买本文件时可获得的所有当前修订均包含在购买本文件中。

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.All current amendments available at time of purchase are included with the purchase of this document.
