ASTM E595-15 Outgassing test - Test Standard 

ASTM E595 Standard Test Method for Total Mass Loss and Collected Volatile Condensable Materials from Outgassing in a Vacuum Environment

ASTM E595-15 Outgassing test - Test Requirement

CVCM （collected volatile condensable materials）≤0.1%

TML （total mass loss）≤1%

WVR （the amount of water vapor regained）

Outgassing test ASTM E595 - Test Conditions 

Pre Condition: 73 F/ 50% RH (24Hours)  ; Post Condition: 73 F/ 50% RH (24Hours)

This test method describes the test apparatus and related operating procedures for evaluating the mass loss of materials being subjected to 125°C at less than 7*10−3 Pa  for 24 h. The overall mass loss can be classified into noncondensables and condensables. The latter are characterized herein as being capable of condensing on a collector at a temperature of 25°C.
