ASTM D2990-95
Historical Standard: ASTM D2990-95 Standard Test Methods for Tensile, Compressive, and Flexural Creep and Creep-Rupture of Plastics
SUPERSEDED (see Active link, below)
ASTM D2990
1. Scope
1.1 These test methods cover the determination of tensile and compressive creep and creep-rupture of plastics under specified environmental conditions (see 3.1.3).
1.2 While these test methods outline the use of three-point loading for measurement of creep in flexure, four-point loading (which is used less frequently) can also be used with the equipment and principles as outlined in Test Methods D790.
1.3 For measurements of creep-rupture, tension is the preferred stress mode because for some ductile plastics rupture does not occur in flexure or compression.
1.4 Test data obtained by these test methods are relevant and appropriate for use in engineering design.
1.5 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.
1.6 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. A specific warning statement is given in 6.8.2.
Note 1This standard and ISO 899 are similar in content, but are not equivalent.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
