ECSS-Q-ST-70-02欧空局除气测试-测试方法
ECSS-Q-ST-70-02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。
ECSS-Q-ST-70-02 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
 
ECSS-Q-ST-70-02除气测试-测试范围
各种各样的有机分子，聚合物和无机材料都可以被测试。这些材料包含：聚合混合物，发泡材料，弹性体，薄膜，胶带，绝缘体，收缩管，胶水，涂料，纺织面料，和轮滑油，这些材料可以在原始接受的状态下测试，也可以通过多种方式固化后测试。
Many types of organic, polymeric, and inorganic materials can be tested by ECSS-Q-ST-70-02 outgassing test. These include polymer potting compounds,foams, elastomers, films, tapes, insulations, shrink  tubings, adhesives, coatings, fabrics, tie cords, and lubricants. The materials may be tested in the “as-received” condition or prepared for test by various curing specifications.
 
ECSS-Q-ST-70-02除气测试-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
