ASTM E595除氣測(cè)試-測(cè)試方法
ASTM E595除氣測(cè)試方法包含使用篩選技術(shù)來確定的材料在真空狀態(tài)下的揮發(fā)性。需要測(cè)試兩個(gè)參數(shù)：總質(zhì)量虧損（TML）和揮發(fā)物質(zhì)冷凝量（CVCM）。另一個(gè)參數(shù)水汽量(WVR), 也可以在完成對(duì)TML和CVCM的測(cè)試后獲得。
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除氣測(cè)試-測(cè)試范圍
各種各樣的有機(jī)分子，聚合物和無機(jī)材料都可以被測(cè)試。這些材料包含：聚合混合物，發(fā)泡材料，彈性體，薄膜，膠帶，絕緣體，收縮管，膠水，涂料，紡織面料，和輪滑油，這些材料可以在原始接受的狀態(tài)下測(cè)試，也可以通過多種方式固化后測(cè)試。
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.
