ASTM E595 Outgassing Services


With the ability to cause damage and failure to mission-critical components, outgassing is an important characteristic to be considered in material selection. Our ASTM E595 testing services help you choose compatible materials that ensure the material meets the Total Mass Loss (TML) and the Collected Volatile Condensable Materials requirements established by NASA and the European Space Agency (ESA).


ASTM E595 Outgassing Test Procedure
During ASTM E595 testing, a material is placed in a thermal vacuum chamber and typically exposed to a 125°C  temperatures and vacuum force up to 5 x 10-5 torr. After a 24-hour outgas exposure, the specimens and the condensing plates are weighed to determine mass loss, and the percentage of the volatile effluents that were collected during testing.


Our ASTM E595 testing services are critical to the material selection process for high vacuum applications. In addition to measuring outgassing levels, our experts can provide testing and data about residual gas analysis, thermal properties and other aerospace properties.

ASTM E595除气测试-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。
Many types of organic, polymeric, and inorganic materials can be tested by ASTM E595 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.
 
ASTM E595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
