This part of ISO 4308 specifies two methods for the selection of wire rope to be used on lifting appliances as designated in ISO 4306-1, one based on the value of the rope selection factor C and the other based on the value of the coefficient of utilization Zp This part of ISO 4308 establishes the minimum requirements for acceptable strength and performance levels of wire ropes with respect to the design, application and maintenance of the lifting appliance. This part of ISO 4308-1 establishes the minimum requirements for the diameters of drums and sheaves that are to be associated with the selected wire rope. A non-exhaustive list of types of lifting appliance to which this part of ISO 4308 is applicable is given in Annex A. Annex B provides some examples of rope selection. Annex C gives factors, additional to those mentioned above, which may need consideration when selecting the wire rope. Annex D specifies the selection method for the diameter of the compensating sheave when used in relation to hoists.
