21、d has been prepared to support Parts 4 to 10 that concern themselves with the particular requirements for steel wire ropes for use in specific applications. The rope designation system described in clause 4 is provided with the intention of it being used to describe the rope in the certificate or in

22、spection 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 designation and classification systems described in clauses 4 and 5 respectively may also be used for ropes not covered

23、 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 conjunction with all other parts of this standard.
