Title:High Strain Rate Tensile Testing of Polymers
Issuing Committee:Plastics Committee
Scope:1. AIMS AND SCOPE1.1 This recommended practice is a guideline for generating high strain rate tensile properties under defined conditionsof unreinforced and reinforced plastics used in the automotive industry. Several types of test specimens areidentified to suit different types of materials and test rates.1.2 This document is intended for strain rates between 10-3/s and 103/s. Test procedures for rates of 10-2/s and below;i.e., quasi-static conditions, are described in ASTM D 638 and ISO 527-1. The procedures in this document includequasi-static testing in order to provide a common test rate for both quasi-static and dynamic test programs. Thegeneral procedures listed in ASTM D 638 and ISO 527-1 should be followed when appropriate.1.3 The main purpose of this document is to determine the relative effects of increasing strain rate on the measuredmaterial properties. Data generated from these tests are comparative in nature. High rate tensile tests will notgenerate basic material properties as accurately as those generated by quasi-static tests.1.4 The scope of this document covers驴 Rigid and semi-rigid thermoplastic molding and extrusion materials, including filled and reinforced compounds inaddition to unfilled types, and驴 Rigid and semi-rigid thermoplastic sheets.Thermosetting materials, rigid cellular materials, and sandwich structures containing cellular material were not evaluatedas part of this document. However, the test procedures may be used as a general guideline for these materials. Thisdocument is not recommended for materials whose internal structure is on the scale of the gage width and length of theselected specimen configuration. Fiber-filled polymers may require additional testing using an alternate sample geometryto establish the effect of strain rate on the measured properties.
