This standard specifies procedures for measuring the tensile properties of molded and extruded plastics over a wide range of strain rates, including high strain rates approaching impact loading situations. These properties are measured through a combination of measurements at low and medium strain rates, the use of mathematical functions for modeling the results, the rate dependence of the parameters, and determination of the parameters at high strain rates by extrapolation. The tensile properties at high strain rates are then derived from calculations. This method avoids the experimental problems of measuring properties at high strain rates and the associated errors.Measurement of properties at low and medium strain rates is recommended in KS M ISO 527, which identifies the types of plastic materials to which this standard can be applied.
