The rope designation sy
21、stem described in clause 4 is provided with the intention of it being used to describe the rope in the certificate or inspection document referred to in the other Parts. The rope classification system described in clause 5 is provided to define which constructions apply to a specific rope class. The
22、 designation and classification systems described in clauses 4 and 5 respectively may also be used for ropes not covered by the other parts of this standard. 1 Scope This part of this European Standard defines terms, specifies designations and classifies steel wire ropes and is for use in conjunctio
23、n with all other parts of this standard. It applies to ropes that have been manufactured after the date of issue of the standard. 2 Normative references Not applicable. 3 Terms and definitions For the purposes of this part of EN 12385, the following terms and definitions apply. 3.1 Wires 3.1.1 outer
