GB/T 1040.2 - 2006 specifies the test conditions for the measurement of tensile performance of molded and extruded plastics. This standard defines the applicable range of molded and extruded plastics, specifies the sample preparation method, and has clear requirements for the shape and size of the sample. Specifies the parameters of material testing machines and other equipment, and standardizes the tensile test operation process, such as loading rate, gauge distance measurement, etc. It also clarifies the calculation and reporting method of results. The tensile performance is related to the actual application performance of plastic products. This standard provides a unified test specification for the plastics industry, helps enterprises control the mass of products, and promotes the development of industry standardization.
