UNE-EN ISO 21970-2:2020

This document specifies the methods of preparation of test specimens and the standard test methods tobe used in determining the properties of thermoplastic polyketone moulding and extrusion materials.Requirements for handling test material and/or conditioning both the test material before mouldingand the specimens before testing are given.The properties have been selected from the general test methods in ISO 10350-1. Other test methods inwide use for or of particular significance to these moulding and extrusion materials are also included inthis document, as are the designatory properties specified in ISO 21970-1.It is intended that the methods of preparation and conditioning, the specimen dimensions and thetest procedures specified in this document be used in order to obtain reproducible and comparabletest results. Values determined will not necessarily be identical to those obtained using specimens ofdifferent dimensions or prepared using different procedures.
