Significance and Use
This test method establishes the short-time hydraulic failure pressure of thermoplastic or reinforced thermosetting resin pipe, tubing, or fittings. Data obtained by this test method are of use only in predicting the behavior of pipe, tubing, and fittings under conditions of temperature, time, method of loading, and hoop stress similar to those used in the actual test. They are generally not indicative of the long-term strength of thermoplastic or reinforced thermosetting resin pipe, tubing, and fittings.
Procurement specifications utilizing this test method may stipulate a minimum and maximum time for failure other than the 60 to 70 s listed in 9.1.3. Either the internal hydraulic pressure or the hoop stress may be listed in the requirements.
Note 1—Many thermoplastics give significantly different burst strengths depending on the time to failure. For instance, significant differences have been observed between failure times of 65 and 85 s.
This test method is also used as a short-term pressurization validation procedure, where the specimens are pressurized to a predetermined minimum pressure requirement.
1.1 This test method covers the determination of the resistance of either thermoplastic or reinforced thermosetting resin pipe, tubing, or fittings to hydraulic presssure in a short time period. Procedure A is used to determine burst pressure of a specimen if the mode of failure is to be determined. Procedure B is used to determine that a specimen complies with a minimum burst requirement.
1.2 This test method is suitable for establishing laboratory testing requirements for quality control purposes or for procurement specifications.
1.3 The values given in parentheses are provided for information purposes only.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
