Standard
ISO 6259-3 Thermoplastics pipes -- Determination of tensile properties -- Part 3: Polyolefin pipes
ISO 6259-3 specifies a method of determining the tensile properties of polyolefin (polyethylene, cross-linked polyethylene, polypropylene, and polybutene) pipes, and the following properties: the stress at yield and the elongation at break.
Sample size:
Type 1 Dog bone : 150mm length, 20mm width
Type 2 Dumbell : 115mm length, 20mm width
Type 3: 250mm length
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 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.
