Introduction Note: Nothing in this standard supercedes applicable laws and regulations. Note: In the event of conflict between the English and domestic language, the English language shall take precedence. Purpose. This qualitative test procedure is used to evaluate sonically welded...
This specification covers poly(vinyl chloride) (PVC) Schedule 40 pipe fittings made from four PVC plastic compounds and intended for use with Iron Pipe Size (IPS) outside-diameter plastic pipe. Fittings fabricated by welding are not included in this specification. Included are...
1.1 This specification covers a coextruded polyethylene composite pressure pipe with a welded aluminum tube reinforcement between the inner and outer layers. The inner and outer polyethylene layers are bonded to the aluminum tube by a melt adhesive. Included is a system of nomenclature for...
5.1 The mechanical performance of welded thermoplastic structures is largely dependent on the quality of the welding operation. It is necessary for fabricators to determine that the proper welding procedures are being followed and that welders maintain their proficiency....
1.1 This specification covers requirements and test methods for fabricated poly(vinyl chloride) (PVC) plastic schedule 40 drainage and DWV fittings to be used with piping manufactured in accordance with Specifications D2665 or F891. These fabricated fittings are manufactured from pipe, or...
Application This procedure is used to evaluate the bond strength of a joint on plastic interior trim assemblies. The parts are generally manufactured by spot, ultrasonic or vibration welding, heat bonding or staking, crimping, and/or other processes. The method may be adapted to any...
5.1 The property KIc determined by this test method characterizes the resistance of a material to fracture in a neutral environment in the presence of a sharp crack under essentially linear-elastic stress and severe tensile constraint, such that (1) the state of stress near the crack front...
5.1 Fracture toughness is expressed in terms of an elastic-plastic stress intensity factor, KJc, that is derived from the J-integral calculated at fracture. 5.2 Ferritic steels are microscopically inhomogeneous with respect to the orientation of individual grains. Also, grain boundaries have...
1.1 This specification covers a coextruded polyethylene composite pressure pipe with a welded aluminum tube reinforcement between the inner and outer layers. The inner and outer polyethylene layers are bonded to the aluminum tube by a melt adhesive. Included is a system of nomenclature for...
5.1 The parameters KEAC or KIEAC determined by this test method characterize the resistance to crack growth of a material with a sharp crack in specific environments under loading conditions in which the crack-tip plastic region is small compared with the crack depth and the uncracked...
