标准摘要
[中文适用范围]： 本部分ISO 12418为消费后聚对苯二甲酸乙二醇酯（PET）瓶回收料建立了一个命名系统，可作为规范的基础。PET瓶回收料的类型通过基于以下指定特性的分类系统进行区分：a) 特性粘度（IV）；b) 由于标签和其他可见污染物、PVC和聚烯烃（包括粘合剂）造成的污染水平；c) 含水量；d) 堆积密度。关于预期应用或加工方法的信息也将有助于分类。本部分ISO 12418适用于所有PET瓶回收料，适用于以粉末、薄片或颗粒形式准备正常使用的材料。本部分不暗示具有相同名称的材料将具有相同的性能。本部分不提供工程数据或加工条件数据，这些数据可能需要为特定应用和/或加工方法指定材料。如果需要此类额外细节，应根据本国际标准第2部分中规定的测试方法进行确定。为了指定热塑性材料用于特定应用或确保可重复加工，可以在数据块5中给出附加要求。 [外文原描述]： ISO 12418‑1:2012 establishes a designation system for post-consumer poly(ethylene terephthalate) (PET) bottle recyclates, which may be used as the basis for specifications. The types of PET bottle recyclate are differentiated from each other by a classification system based on appropriate levels of the following designatory properties: intrinsic viscosity (IV); levels of contamination due to the label and other visible contaminants, PVC and polyolefins (including adhesive); water content; bulk density. Information regarding the intended application or method of processing will also assist in classification. ISO 12418‑1 is applicable to all PET bottle recyclates. It applies to materials ready for normal use in the form of powder, flakes or pellets. It is not intended to imply that materials having the same designation will give the same performance. ISO 12418‑1 does not provide engineering data or data on processing conditions which might be required to specify a material for a particular application and/or method of processing. If such additional details are required, they shall be determined in accordance with the test methods specified in ISO 12418‑2. In order to specify a thermoplastic material for a particular application or to ensure reproducible processing, additional requirements may be given in an additional data block (data block 5).
