ASTM WK24244

    New Practice for Guided Side Bend Testing of Polyethylene Pipe Butt Fusion Joints

    (What is a Work Item?)

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


    1. Scope

    1.1 This practice provides information on apparatus, specimen preparation, and procedure for conducting a guided three-point side bend evaluation of a transverse specimen cut from a bend coupon removed from a pipe butt fusion joint in polyethylene pipe having a wall thickness 1.00 in. (25.4 mm) and thicker. This practice provides a means to assess ductility of a butt fusion joint by applying a lateral (side) bending strain across a specimen that includes the entire butt fusion cross section from outside diameter to inside diameter. 1.2 No test values are provided by this practice. The result is a non-numerical report. Criteria for test result evaluation are provided in standards or codes that specify the use of this practice by comparison to benchmark laboratory results or comparison to example results presented in Appendix X1 to this practice. 1.3 Units--The values stated in inch-pound units as specified in this practice are to be regarded as the standard. The values stated in parenthesis are mathematical conversions to SI units that are provided for information only and are not considered standard. 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 the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Note 1--Laboratory methods that are commonly used for testing polyethylene butt fusion joints include Test Methods D638 and F2634. Note 2--This practice has been developed for use on butt fusion joints in polyethylene pipe with a wall thickness of 1.00 in. (25.4 mm) or greater. The practice may be used on butt fusion joints in polyethylene pipe with thinner wall thicknesses. However, the applicability of the practice should be determined by the user of the practice.

    This practice will provide a method to assess ductility of butt fusion joints made on polyethylene pipe.
