标准摘要
[中文适用范围]： 本国际标准规定了热固性模塑材料模压试样的模压收缩率和热处理后收缩率的测定方法。 这些特性对于热固性材料的生产控制和检查制造的均匀性很有用。 此外，了解热固性材料的初始收缩对于模具的构造非常重要，而了解后收缩对于确定模制材料是否适合制造具有精确尺寸的模制件也很重要。 [外文原描述]： ISO 2577:2007 specifies a method of determining the moulding shrinkage and the shrinkage after heat treatment of moulded test specimens of thermosetting moulding materials. These characteristics are useful for the production control of thermosetting material and for checking uniformity of manufacture. Furthermore, knowledge of the initial shrinkage of thermosetting materials is important for the construction of moulds, and knowledge of post-shrinkage for establishing the suitability of the moulding material for the manufacture of moulded pieces with accurate dimensions.
