ISO 16625:2013规定了各种机构分类、绳索类型、绳索职责和卷绕类型的最小实际设计因素Zp，并演示了如何使用这些因素来确定钢丝绳的最小断裂力。 它规定了各种机构分类、绳索类型和绳索任务的卷筒和滑轮的选择因素，以及如何使用这些因素来确定与所选钢丝绳相关联的卷筒和滑轮的最小实际直径。

ISO 16625:2013 specifies the minimum practical design factors, Z_p, for the various classifications of mechanism, rope types, rope duties and types of spooling and demonstrates how these are used in the determination of the minimum breaking force of the wire rope. It specifies the selection factors for drums and sheaves for the various classifications of mechanisms, rope types and rope duties and how these are used in the determination of the minimum practical diameters of drums and sheaves that work in association with the selected wire rope.
