标准范围

ISO 12418？1:20 12建立了消费后聚对苯二甲酸乙二醇酯（PET）瓶回收物的指定系统，该系统可用作规范的基础。PET瓶回收物的类型通过基于以下指定性质的适当水平的分类系统彼此区分:特性粘度(IV)；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；含水量；堆积密度。关于预期应用或处理方法的信息也将有助于分类。ISO 12418？1适用于所有PET瓶回收物。它适用于粉末、薄片或颗粒形式的可正常使用的材料。这并不意味着具有相同名称的材料将提供相同的性能。ISO 12418？图1没有提供工程数据或关于加工条件的数据，这些数据可能需要为特定应用和/或加工方法指定材料。如果需要此类附加细节，应根据ISO 12418？中规定的试验方法确定。2.为了指定用于特定应用的热塑性材料或确保可再现的加工，可以在附加数据块(数据块5)中给出附加要求。

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).
