ASTM WK26568

    New Practice for In-Field Tensile Testing of Polyethylene (MDPE and HDPE) Butt-Fused Joints

    (What is a Work Item?)

    Developed by Subcommittee: F17.40 | Committee F17 | Contact Staff Manager


    1. Scope

    1.1 This practice covers the in-field preparation and testing of tensile test samples that may be used to provide an indication as to the tensile performance of butt-fused medium-and high-density polyethylene (MDPE and HDPE) joints relative to their parent materials. 1.2 No numerical results are determined by this practice. The result of this practice is a either a passing or failing result. Failing results should be investigated by a competent individual and the cause(s) corrected. 1.3 This practice is applicable for testing butt-fused joints in pipes of 2.37-in. (60.3-mm) outside diameter and larger with a maximum wall thickness of 5 in. (127 mm). 1.4 This practice is intended for evaluating butt fusions made from like parent materials. This practice may be adapted for use by technically competent individuals to evaluate butt fusions made from unlike parent materials. 1.5 This practice may be used, where allowed, for fusion equipment operator qualification, fusion procedure qualification, and fused joint production quality assurance. 1.6 Units--The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.7 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.

    No active standard covers the production of a tensile coupon in field using commonly available hand tools and in-field tensile testing of this coupon. It is envisioned that this test would be used for in-field evaluation of fusion quality, adequate equipment performance, and operator competency.

    The title and scope are in draft form and are under development within this ASTM Committee.
