Introduction General This standard deals with low pressure tests at room temperature. The object of this .test is to determine the ability of components@ equipment or other articles to be stored@ transported or used under low air pressure conditions. Note.?? Articles to be stored@ transported or used under a simultaneous combination of high or low temperature and low air pressure should@ where the combination is important for the stresses imposed on the article or for the failure mechanisms@ be tested according to: - IEC Publication 68-2-40: Basic Environmental Testing Procedures@ Part 2: Tests??Test Z/AM: Combined Cold/Low Air Pressure Tests@ and - IEC Publication 68-2-41: Part 2: Tests??Test Z/BM: Combined Dry Heat/Low Air Pressure Tests.
