Scope and application
This programme is applicable for the approval of material manufacturers of:
as referred in the Society's rules and standards. For a description of general requirements, conditions and procedures related to the approval, please refer to DNVGL CP 0346 which shall be applied in combination with this programme.
The product(s) used for approval testing (see Sec.3) will place limitations on the range of approval. The approval will be limited to:
wire rope type
wire rope construction
maximum wire rope diameter
core construction (i.e. fibre, steel etc.)
breaking load of the wire rope
tensile strength grade of the wires of the wire rope
However, test data supplied for one construction may cover wire ropes of other constructions in the same wire rope class (for definition of classes, see API 9A), provided tested and covered constructions have:
same type of core
same type of lay type and direction
same wire shape, grade and finish
same number of strands
same construction type (see ISO 17893 Table 2), defined as follows:
single lay types
parallel lay types, divided as follows:
combined parallel lay (WS) types
multiple operation lay types, divided as follows:
Approval will be given for the manufacture of products and materials in accordance with the Society's rule requirements. However, in case of absence of relevant rules and subject to prior agreement, approval may be given for the manufacture of products and materials specified in recognised standards.
when wire rope manufacturer operates their own steel making and/or rolling facilities to produce their own pre-material (wires/billets/ingot
when pre-materials for wire rope making are not produced by the wire rope manufacturer, these shall be procured from steelmaker/rolling mill correspondingly approved by the Society.
