1.1 This practice provides information on apparatus, test specimen preparation, and procedures for conducting a three-point guided side bend test on a specimen cut from a polyethylene pipe butt fusion joint prepared in accordance with Practice F2620 or other joining procedures with a wall thickness 1.00 in. (25.4 mm) and thicker. This test determines ductility of a butt fusion joint by applying a lateral (side) bending strain across a test specimen that includes the entire butt fusion cross section from outside diameter to inside diameter. 1.2 Laboratory methods that are commonly used for testing polyethylene butt fusion joints include Test Methods D638 and F2634. 1.3 Butt fusion joints made on any polyethylene pipe may be tested using this method. This practice may be used to evaluate butt fusion joints made in pipes produced from other thermoplastic materials provided applicability of this practice has been determined. 1.4 No test values are provided by this practice. Test results are acceptable/unacceptable. 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.
This practice will provide a quick, simple, test that can be performed in the field to evaluate fusion quality.
