NASA General Specification No. SP-R-0022 Vacuum Stability Requirements of Polymeric Material for Spacecraft Application. NASA SP-R-0022热空间材料筛选试验方法-热真空释气试验(美国宇航局标准)
ASTM E595 Standard Test Method for Total Mass Loss and Collected Volatile Condensable Materials from Outgassing in a Vacuum Environment.
国外涉及热真空释气的标准试验方法的有5个,分别是美国材料和试验协会标准ASTM E595,欧空局标准ECSS-Q-ST-70-02,美国宇航局Johson 宇航中心标准( Johnson Space Center) JSC-SP-R-0022,美国宇航局Marshall宇航飞行器中心( Marshall Space Flight Center) 标准MSFC-SPEC-1443 和MSFC-PROC-3257。目前国际通用的挑选宇航用非金属材料的热真空释气标准是ASTM E595 和ECSS-Q-ST-70-02。
ASTM E595热真空释气测试 ASTM E595 在真空环境中除气作用引起的总质量损失和挥发物质冷凝量的测试方法 ASTM E595 Standard Test Method for Total Mass Loss and Collected Volatile Condensable Materials from Outgassing in a Vacuum Environment ASTM E595热真空释气测试-测试方法 ASTM E595除气测试方法包含使用筛选技术来确定的材料在真空状态下的挥发性。需要测试两个参数:总质量亏损(TML)和挥发物质冷凝量(CVCM)。另一个参数水汽量(WVR), 也可以在完成对TML和CVCM的测试后获得。 ASTM E595 outgassing test, This test method covers a screening technique to determine volatile content of materials when exposed to a vacuum environment. Two parameters are measured: total mass loss (TML) and collected volatile condensable materials (CVCM). An additional parameter, the amount of water vapor regained (WVR), can also be obtained after completion of exposures and measurements required for TML and CVCM
ASTM E595热真空释气测试-测试项目和要求: TML (total mass loss)总质量亏损,要求≤1% CVCM (collected volatile condensable materials)挥发物质冷凝量, 要求≤0.1% WVR (the amount of water vapor regained)水汽量
