ASTM A1023:15 pdf download.Standard Specification for Stranded Carbon Steel Wire Ropes for General Purposes.
6.6.2.3 For single layer ropes with shaped strands, for example, flattened (triangular) strand, the length of lay of the finished rope shall not exceed ten times the nominal rope diameter.
6.7 Mechanical Properties:
6.7.1 Breaking force—Values for minimum breaking force for the more common classes of rope are specified in Tables 7-32 of this standard.
6.7.1.1 The minimum breaking force for other classes and constructions not covered by the tables, shall be agreed UOfl by the manufacturer and the purchaser.
6.7.1.2 Wire ropes with minimum breaking forces less than those allowed in this specification may be accepted by prior agreement between the supplier and purchaser and shall be regarded as beyond the scope of this specification.
6.7.2 Mass—The (approximate) nominal rope mass shall be as given in Tables 7-32 or as specified by the manufacturer.
6.7.3 Length—The actual length of rope supplied, expressed in feet or meters, shall be the specified length subject to the following limits of tolerance:
(a) Up to and including 1300 ft [400 in]: +5.0 % of specified length,
(b) Over 1300 ft up to 3280 ft [400 m to 1000 ml: +66 ft 120 ml, and
(c) Over 3280 ft 11000 ml: +2.0 % of specified length.
No’FE 3 The rope shall be measured under no load. Ropes required with more restrictive length tolerance shall be agreed upon by the supplier and
purchaser.
7. Rope Workmanship and Finish
7.1 Strand:
7.1.1 Strand wires shall be tight and uniform. All the wire layers in a strand shall have the same direction of lay. The lay lengths of corresponding wire layers in strands of the same size shall be uniform.
7.1.2 Center wires and fiber centers of strands shall he of a size to provide sufficient support to enable the covering wires to be evenly laid.
7.2 Rope—The rope shall be uniformly made and the strands shall lie tightly on the core or the underlying strands.
7.2.1 The core of a stranded rope, except for swaged (compacted) ropes. shall he designed so that in a new rope under no load there is clearance between the outer strands.
8.1 Wire ropes manufactured in accordance with this specification shall be capable of meeting all the appropriate requirements as specified in 8.2. The manufacturer shall be able to
demonstrate compliance with this specification by either:
8.1.1 Testing each production length in accordance with 8.2, or
8.1.2 Operating a quality assurance system that includes a sampling program that meets the following requirements as a minimum:
8.1.2.1 For each size and grade of a given rope construction, the manufacturer shall present evidence from testing, if requested by the purchaser, of a minimum of three production
lengths representing the current design. The purpose of these tests is to assure the manufacturer’s ability to produce a rope that conforms to the minimum requirements.
