Description
1.1 This test method covers the determination of the load-deflection behavior of thermoplastic pipe wall sections under parallel plate loading conditions.
Note 1 – These are not full pipe section tests, but pipe wall segment tests. The results of these tests will be different from pipe stiffness tests per Test Method D 2412, although they may be proportional. This test provides quite different information, including , stress relaxation under constant strain, and comparisons of the function and stiffness of different pipe wall designs or materials.
1.2 This test method covers a loading test for determining the wall stiffness of a thermoplastic-pipe wall under a combined load of bending and compression. Changes in pipe wall profile geometry under load may also be determined.
1.3 This test method covers thermoplastic pipe.
1.4 The characteristics determined by this test method are wall stiffness and changes in profile wall dimensions at specific deformations.
1.5 The characteristics determined by this test method are wall stiffness, profile wall efficiency, and for some wall elements stability at specific Strain levels.
1.6 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.7 The text of this specification references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification.
1.8 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.
