本标准规定了热收缩薄膜收缩性能的热缩强度、冷缩强度和收缩率的试验方法。本标准适用于以聚乙烯、乙烯共聚物及其混合物生产的热收缩薄膜,其他类型材料的热收缩薄膜也可参照执行。
本标准规定了滚动轴承运输用托盘和木箱的结构型式、尺寸、技术要求、标志、检测方法、检验规则等。本标准适用于外径不大于440 mm、采用缠绕包裹或纸箱包装的滚动轴承运输用托盘和木箱。对于尺寸超过本标准规定范围的滚动轴承,可参照使用。
The purpose of this standard is to describe a conventional method for measuring the shrinking and contracting forces of heatshrinkable films made from polyethylene, ethylene copolymers and their mixtures. The method described in this standard can possibly be applied to other materials under proper operating conditions. NOTE 1 This method also allows a shrinkage ratio to be assessed. However, the reference method for measuring the shrinkage ratio is ISO 11501, Plastics — Film and sheeting — Determination of dimensional change on heating.
