Tensile Test Methods for Plastics: ISO 527 and JIS K 7161

Resin materials (plastics) are found in a wide variety of items used on a daily basis. Recently, plastics have started to be used as structural materials in transportation equipment, such as automobiles and aircraft, due to their strength and light-weight nature. In these applications, it is important to understand the mechanical strength properties of these plastics. ISO 527 and JIS K 7161 outline methods for testing the tensile strength of plastics and other resin materials. Included in these methods are accuracy specifications for the test frame and test accessories. The contents of ISO 527 and JIS K 7161 are basically the same, but differ from the equivalent ASTM standard for tensile testing of plastics, ASTM D638.
