20、thylene; d) polypropylene. 3.2 General The yarns from which a rope is constructed shall be made from continuous filament fibres in the cases of polyamide-and-polyester ropes and from monofilament or film tapes in the cases of polyethylene and polypropylene ropes. The strands of the rope shall be wel
21、l formed and free from grooves and sunken yarns, and all strands in a rope shall contain the same number of yarns. Each rope shall be well laid and free from defects. The rope in each coil shall be continuous throughout its length and there shall be no loose ends, splices, or joins in the rope or in
22、 any of its strands. The linear density and breaking strength of a rope determined in accordance with 6.5 and 6.7 shall, subject to the relevant tolerances laid down in SANS 977, comply with the requirements specified in tables 1-6 (as applicable), appropriate to the nominal diameter in the identifi
23、cation code specified by the purchaser. 3.3 Identification 3.3.1 Identification code A rope shall be identified by the appropriate code letters for its construction and composition given in (a) and (b) below, followed by the numerical value of its nominal diameter in millimetres. a) Construction cod
24、e letters H = hawser (plain)-laid P = plaited (cross-laid) b) Composition code letters A = polyamide E = polyester T = polyethylene R = polypropylene (The following is an example of an identification code: HR6) 3.3.2 Identification threads a) Ropes of nominal diameter 16 mm or more shall be identifi
25、ed as follows: 1) Polyamide ropes: by a GREEN thread in the centre of one strand of the rope. 2) Polyester ropes: by a BLUE thread in the centre of one strand of the rope. 3) Polyethylene ropes: by an ORANGE thread in the centre of one strand of the rope, or by the entire rope being of an ORANGE col
26、our. 4) Polypropylene ropes: by a BROWN (BRICK) thread in the centre of one strand of the rope, or by the entire rope being of a BROWN (BRICK) colour. SANS 943:2008 Edition 2.3 7 b) When so required by the purchaser, a rope of any nominal diameter shall have, in addition, external identification thr
27、eads of the colour specified by the purchaser. Where external identification threads are required in 8-strand ropes, the thread(s) should be in an S-lay strand. 3.4 Direction of lay Unless otherwise required by the purchaser, a hawser (plain)-laid rope shall be of Z-lay. 3.5 Length of 10 lays The le
28、ngth of 10 lays of a polyamide and polyester hawser (plain)-laid rope, determined in accordance with 6.6, shall, unless otherwise required by the purchaser, not exceed the appropriate maximum given in table 7. 3.6 Resistance to kinking When a rope is tested in accordance with 6.8, no kinking of the
29、rope shall occur. 4 Packing and marking 4.1 Packing The rope shall be made up into coils of length approximately 220 m, unless otherwise specified by the purchaser or impracticable. Each end of the rope shall be so secured as to prevent unlaying, and the rope shall be neatly coiled, tied, and so wra
30、pped as to prevent any disturbance of the lay during normal transportation, storage, and handling. Metal bands or wire shall not be used to tie the coils. 4.2 Marking The following information shall appear in legible and indelible marking on a label securely attached to each coil: a) the manufacture
31、rs name or trade mark (or both); b) the identification code; c) the nominal diameter; d) the net mass of the coil when packed; e) when packed by length, the length of the coil. 4.3 Additional markings When so required by the purchaser, labels shall bear information additional to that specified in 4.
