The two most important criteria when selecting a test method are the availability of a standard test method and the ability of the test method to produce consistent and reliable engineering data for a range of service conditions. When planning a test strategy consider criteria...

For this reason, these parameters must be specified when reporting T g measurements and when comparing data of different polymeric materials...
