1.1 This practice provides standardized sample butt fusion preparation, conditioning, and testing conditions for tension testing of specimens prepared from sample butt fusion joints or hydrostatic tests of sample butt fusion joints in accordance with:
1.1.1 Test Method , tension testing;
184.108.40.206 The preparation or use of tensile specimens other than Test Method Type I through Type V is beyond the scope of this practice.
1.1.2 Test Method , constant (sustained) hydraulic pressure testing;
1.1.3 Test Method , short-term hydraulic pressure testing.
1.1.4 It is not within the scope of this practice to include plastic materials other than polyethylene or other tests for butt fusions. The exclusion of other plastic materials and other tests does not imply that other plastic materials are suitable or unsuitable for butt fusion, or that the tests cited herein are adequate or inadequate for qualitative characterization and for research and development of butt fusion joints, or that other tests do not have lesser, equal, or greater utility for such purpose.
1.1.5 The evaluation of test results and the determination of test result evaluation criteria are not within the scope of this practice. This practice is limited to standardized butt fusion test specimens and testing conditions for the comparison of test data from multiple parties.
1.1.6 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.1.7 In this standard, text in parentheses, notes in the body of the standard and appendices are informational and non-mandatory. For tables in the body of the standard, table notes are mandatory.
1.2 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.
