Significance and Use | ||||||||||||||
4.1 This test method does not purport to interpret the data generated. 4.2 This test method is intended to compare slow-crack-growth (SCG) resistance for a limited set of HDPE resins. 4.3 This test method may be used on virgin HDPE resin compression-molded into a plaque or on extruded HDPE corrugated pipe that is chopped and compression-molded into a plaque (see 7.1.1 for details). |

1. Scope | ||||||||||||||
1.1 This test method is used to determine the susceptibility of high-density polyethylene (HDPE) resins or corrugated pipe to slow-crack-growth under a constant ligament-stress in an accelerating environment. This test method is intended to apply only to HDPE of a limited melt index and density range as defined in AASHTO Standard Specification M 294. This test method may be applicable for other materials, but data are not available for other materials at this time. 1.2 This test method measures the failure time associated with a given test specimen at a constant, specified, ligament-stress level. 1.3 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. 1.4 Definitions are in accordance with Terminology AASHTO Standard Specification M 294, and abbreviations are in accordance with Terminology D1600, unless otherwise specified. 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. |
