塑料 热塑性材料的压模塑试样

[中文适用范围]： 本文件规定了热塑性塑料在制备压模测试样本以及可加工或冲压测试样本的板材时应遵循的一般原则和程序。 注：为了获得可重复状态的模制品，该程序的主要步骤（包括八种不同的冷却方法）已标准化。 对于每种材料，所需的成型温度和冷却方法在该材料的相应国际标准中给出或由有关各方商定。 本文件不适用于增强热塑性塑料。 [外文原描述]： This document specifies the general principles and the procedures to be followed with thermoplastics in the preparation of compression-moulded test specimens, and sheets from which test specimens can be machined or stamped. NOTE In order to obtain mouldings in a reproducible state, the main steps of the procedure, including eight different cooling methods, are standardized. For each material, the required moulding temperature and cooling methods are given in the appropriate International Standard for the material or as agreed between the interested parties. This document is not applicable to reinforced thermoplastics.
