标准摘要
[中文适用范围]： ISO 14527 的这一部分规定了测试样品的制备方法以及用于确定脲醛和脲/三聚氰胺甲醛粉末模塑料（UF- 和 UF/MF-PMC）性能的测试方法。 这里给出了处理测试材料以及成型前测试材料和测试前样本的调节要求。 给出了制备测试样品的程序和条件以及测量制作这些样品的材料性能的程序。 列出了适合且必要的 PMC 特性和测试方法。 这些特性选自 ISO 10350-1 中的一般测试方法。 ISO 14527 的这一部分还包括广泛用于 PMC 或对 PMC 特别重要的其他测试方法，以及 ISO 14527-1 中的指定属性。 为了获得可重复和可比较的测试结果，有必要使用本文规定的制备和调节方法、样本尺寸和测试程序。 测定的值不一定与使用不同尺寸的样本获得的值或使用不同程序制备的值相同。 [外文原描述]： This part of ISO 14527 specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of urea-formaldehyde and urea/melamine-formaldehyde powder moulding compounds (UF- and UF/MF-PMCs). Requirements for handling test material and for conditioning both the test material before moulding and the specimens before testing are given here. 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 PMCs are listed. 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, PMCs are also included in this part of ISO 14527, as are the designatory properties found in ISO 14527-1. In order to obtain reproducible and comparable test results, it is necessary to use the methods of preparation and conditioning, the specimen dimensions and the test procedures specified herein. Values determined will not necessarily be identical to those obtained using specimens of different dimensions or prepared using different procedures.
