DIN Standards Committee Plastics

Overview

This part of ISO 9988 specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of polyoxymethlene (POM) moulding and extrusion materials. Requirements for handling test materials and for conditioning both the test materials before moulding and the specimens before testing are specified. Procedures and conditions for the preparation of test specimens and procedures for measuring properties of the materials from which these specimens are made are given. Properties and test methods which are suitable and necessary to characterize POM moulding and extrusion materials are listed. The properties have been selected from the general test methods as specified in ISO 10350-1:1998. Other test methods in wide use for or of particular significance to these moulding compounds, such as the designatory properties from ISO 9988-1 (melt flow rate and tensile modulus) are also included in this part of ISO 9988. In order to obtain reproducible and comparable test results, it is necessary to use the methods of preparation and conditioning of the specimens. The specimen dimensions and the test procedures specified hereinafter. Values determined will not necessarily be identical to those obtained using specimens of different dimensions or prepared using different procedures. The committee responsible for this standard is Working Committee NA 054-02-10 AA "Thermoplast-Formmassen" ("Thermoplastic materials") at DIN.
