ISO 13953 Complete Guide to the Butt-Fused PE Joint Tensile Test

ISO 13953 Polyethylene(PE) pipes and fittings - Determination of the tensile strengt and failure mode of test pieces from a butt-fused joint

ISO 13953 specifies a destructive tensile test method for assessing the quality of butt‑fused joints in polyethylene (PE) pipes and fittings by measuring the tensile strength and failure mode of machined test pieces taken from the welded joint. It only applies to PE pipes with nominal outer diameter dn≥90 mm, and serves as a core quality verification tool alongside other joint test methods for plastic piping systems. 

ASTM F2634 Complete Technical Guide to the Tensile-Impact Test for PE Butt Fusion Joints

ASTM F2634 Standard Test Method for Laboratory Testing of Polyethylene (PE) Butt Fusion Joints Using Tensile-Impact Method

ASTM F2634 defines a high-speed tensile impact test to evaluate short-term mechanical integrity of polyethylene butt fusion welds. It is explicitly noted similar to ISO 13953 but differs fundamentally in strain rate (impact speed vs slow static tensile speed). It qualifies field welds, optimizes fusion parameters, and pairs with long-term pressure testing to verify both short and long-term joint performance.
