ASTM D 1248 – Standard Specification for Polyethylene Plastics Extrusion Materials for Wire and Cable – Testing Equipment
4 Classification4.1 This specification recognizes that polyethylene plastics are identified primarily on the basis of two characteristics, namely, density and flow rate (previously identified as melt index). The former is the criterion for assignment as to type, the latter for designation as to category. Other attributes important to the user for certain applications are covered…
Performance Testing of Stretch Wrap Films
AHP manufacture testing equipment for stretch-wrap films. Stretch wrap films are highly stretchable plastic films that are wrapped around certain items, as often used in the packaging industry. The main function of the film is to improve it’s loading stability for transportation, storage and contamination protection. Stretch-wrap films are commonly made of PE (LLDPE , VLDPE, PVC ….). Critical…

ISO 13845 – Elastomeric-Sealing-Ring-Type Socket Joints for use with Unplasticized Poly(vinylchloride) (PVC-U) Pipes — Test Method for Leaktightness Under Internal Pressure and with Angular Deflection – Testing Equipment
2 PrincipleA joint assembly as test piece consisting of a PVC-U pipe mounted into a PVC-U socket is subjected, within a specified temperature range, to a specified internal pressure regime for a specified test period whilst the pipe is also subject to an angular deflection in the socket. While under pressure the test piece is…
EN 12295 Test Method for Resistance of Joints to Pressure Cycling / Testing Equipment
1 Scope This standard specifies a method for testing the resistance of joints to pressure cycling. It is applicable to piping systems based on rigid or flexible thermoplastics pipes intended to be used in hot and cold water applications. 3 Apparatus 3.1 Pressurizing device, capable of applying and regulating the water pressure in the test…
BS ISO 19893 Thermoplastics Pipes and Fittings for Hot and Cold Water — Test Method for the Resistance of Mounted Assemblies to Temperature Cycling / Testing Equipment
2 PrincipleA test assembly of pipes and fittings (see Figure 1) is subjected to temperature cycling by the passage ofwater under pressure using hot and cold water alternately, for a specified number of cycles.While being subjected to temperature cycling, parts of the assembly of pipes and fittings are maintained under tensile stress and/or flexural strain…
