Standard Test Method for Cyclic Pressure Strength of Reinforced, Thermosetting Plastic Pipe
SIGNIFICANCE AND USE
5.1 The values obtained by this test method are applicable only to conditions that specifically duplicate the procedures used.
5.2 After the regression characteristics of a pipe material and manufacturing process have been determined by this test method, one pressure may be used for quality-control purposes. This pressure shall be one of the points used in the original determination and be agreed upon between the individuals concerned.
5.3 This test method deals with cyclic internal pressure performance of a pipe and omits creep and nonrecoverable deformation measurements.
5.4 For determination of the cyclic hydrostatic design basis using data from this test method see Practice D2992.
5.5 In the application of the following test requirements and recommendations it is assumed that test specimens of a given sample of pipe are truly representative of that material and manufacturing process. In tests conducted to show the effect of temperature and pressures on the life span of the pipe, great care must be taken to ensure that the specimens being tested are representative of the group being studied. Departure from this assumption could introduce discrepancies that are greater than those introduced by departure from the details of the procedure outlined in this test method.
SCOPE
1.1 This test method covers the determination of the failure characteristics of reinforced plastic pipe when subjected to cyclic internal hydraulic pressure. It is limited to pipe in which the ratio of outside diameter to wall thickness is 10:1 or more.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values in parentheses are for information only.
1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Note 1: There is no known ISO equivalent to this standard.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
