《GB/T 22236-2008塑料的检验 检验用塑料制品的粉碎》由TC251（全国危险化学品管理标准化技术委员会）归口，主管部门为国家标准化管理委员会。
本标准为首次发布。本标准描述的方法适用于模制塑料、塑料半成品和塑料成型部件。粉碎由制品的预粉碎和最终粉碎所组成。根据被粉碎的制品类型、研究目的和被粉碎材料的所需粒度，选择适当的方法。 本标准等同采用ＤＩＮ５３７３３：１９７６《塑料的检验―――检验用塑料制品的粉碎》（英文版）。
为便于使用，本标准做了下列编辑性修改：
ａ）删除已经作废的引用ＤＩＮ５３７３８标准。
ｂ）删除ＤＩＮ５３７３３中的说明部分。

Scope

The analysis and testing of many plastic products require a sample with a particularly large specific surface area, such as the determination of extractable components. Therefore, plastic products often need to be shredded. The methods described in this standard are applicable to molded plastics, plastic semi-finished products and plastic molded parts. Crushing consists of pre-crushing and final crushing of the product. Select the appropriate method according to the type of product being pulverized, the purpose of the research and the desired particle size of the pulverized material. Note: It is not possible to give appropriate equipment for any test within the scope of this standard. The purpose of this standard is to supplement sufficient information to many standards and guidelines, to provide the most appropriate comminution method, and to provide various possible useful methods for the comminution of the tested samples.
