Plastics - Polyketone (PK) moulding and extrusion materials - Part 2: Preparation of test specimens and determination of properties (ISO 21970-2:2019) 塑料聚酮模塑和挤塑材料第2部分:试样制备和性能测定
发布日期: 2019-09-04
实施日期: 2019-09-04
本文件规定了试样的制备方法和测定热塑性聚酮模塑和挤出材料性能所用的标准试验方法。给出了模塑前处理试验材料和\/或调节试验材料和试验前试样的要求。性能选自ISO 10350-1中的一般试验方法。本文件还包括广泛用于或对这些模塑和挤压材料具有特殊意义的其他试验方法,以及ISO 21970-1中规定的指定性能。本文件中规定的制备和调节方法、试样尺寸和试验程序旨在获得可重复和可比的试验结果。所确定的数值不一定与使用不同尺寸试样或使用不同程序制备的数值相同。
This document specifies the methods of preparation of test specimens and the standard test methods to be 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 moulding and the specimens before testing are given. The properties have been selected from the general test methods in ISO 10350‑1. Other test methods in wide use for or of particular significance to these moulding and extrusion materials are also included in this 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 the test procedures specified in this document be used in order to obtain reproducible and comparable test results. Values determined will not necessarily be identical to those obtained using specimens of different dimensions or prepared using different procedures.
