指定用于一般提升目的的链条的特性，以及滑轮的轮缘轮廓和U形夹的链条连接端。包括尺寸（单位:mm）、互换性极限（非实际公差）、长度测量、验证试验和最小抗拉强度。附录A给出了原始英寸/磅值。

Specifies characteristics of chains used for general lifting purposes, together with the rim profiles of sheaves and the chain attachment ends of clevises. Covers dimensions (in mm), limits for interchangeability (not the actual tolerances), length measurement, proof testing and minimum tensile strengths. Annex A gives the original inch/lb values.
