标准摘要
[中文适用范围]： 本文件规定了热塑性材料注塑测试样本时应遵循的一般原则，并给出了制备两种类型样本以获取参考数据（即 ISO 20753 中规定的 A1 型和 B1 型测试样本）的模具设计细节，并为建立可重复的成型条件提供基础。 其目的是提供成型工艺主要参数的一致描述，并建立报告成型条件的统一做法。 可重复制备测试样本所需的特定条件因所使用的每种材料而异，并在相关材料的国际标准中给出或由有关各方商定。 注：丙烯腈/丁二烯/苯乙烯 (ABS)、苯乙烯/丁二烯 (SB) 和聚甲基丙烯酸甲酯 (PMMA) 的实验室间测试表明，模具设计是可重复制备测试样本的重要因素。 [外文原描述]： ISO 294-1:2017 specifies the general principles to be followed when injection moulding test specimens of thermoplastic materials and gives details of mould designs for preparing two types of specimen for use in acquiring reference data, i.e. type A1 and type B1 test specimens as specified in ISO 20753, and provides a basis for establishing reproducible moulding conditions. Its purpose is to provide consistent descriptions of the main parameters of the moulding process and to establish a uniform practice in reporting moulding conditions. The particular conditions required for the reproducible preparation of test specimens will vary for each material used and are given in the International Standard for the relevant material or are to be agreed upon between the interested parties. NOTE Interlaboratory tests with acrylonitrile/butadiene/styrene (ABS), styrene/butadiene (SB) and poly(methyl methacrylate) (PMMA) have shown that mould design is an important factor in the reproducible preparation of test specimens.
