1.1 This test method covers an un-notched constant ligament stress (UCLS) test for use with HDPE materials that contain post-consumer recycled HDPE (PCR-HDPE). Contaminants in the PCR-HDPE can initiate stress cracks at elevated temperatures, and this test method evaluates the response of these materials to a constant applied stress.

1.2 The test method is focused on HDPE corrugated pipe containing PCR-HDPE, but can be used in other applications where PCR-HDPE is used.

1.3 The test utilizes the same devices used to perform the NCTL test (Test Method D5397) and the NCLS test (Test Method F2136), but the test is conducted with different specimens and with the use of water instead of a surfactant solution. The test specimen is larger than standard NCLS and NCTL specimens to increase the number of contaminant particles in the specimen that might grow cracks.

1.4 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.

1.5  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.
