1. Scope

1.1 This guide covers procedures for determination of the temperature of deflection under load (bending stress under three-point loading) of different types of material.

1.2 This guide is identical to ISO 75-1. This guide is comparable to Test Method D 648, but neither standard should be substituted for the other. The two standards may differ with respect to test specimen dimensions, test specimen conditioning, test equipment, testing conditions, etc. The two procedures may not give the same results.

1.3 The procedures specified are suitable for assessing the behavior of different types of material at elevated temperature under load at a specified rate of temperature increase. The results obtained do not necessarily represent maximum use temperatures because, in practice, essential factors such as time, loading conditions, and nominal surface stress may differ from the test conditions.

1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
