ISO 9554-2010 pdf free.Fibre ropes一General specifications.
ISO 9554 specifies the general characteristics of fibre ropes and their constituent materials. It is intended to be used in conjunction with the standards for the individual types of fibre rope, which cover the physical properties and specific requirements for that particular product type.
This International Standard also gives some information on the use of fibre ropes and also on their inspection and retirement criteria.
This International Standard does not intend to address all of the safety matters associated with its use. It is the responsibility of the user to select a rope type of the size and with the physical properties to meet the requirements of the application and to determine the applicability of regulatory limitations pnor to its use.

4.1 Constituent materials
The following materials are considered in this International Standard:
a) natural fibres:
— sisal;
— manila:
b) man-made fibres:
— polyamide;
— polyester;
— polypropylene;
— polyethylene;
— mixed polyolefin;
— polyester/polyolefin dual fibres;
— high modulus polyethylene.
Typical characteristics for these materials are given in Annex A. Specific applications should involve technical
discussions with rope manufacturers.
4.2 Construction and structure
Unless otherwise specified. 3-, 4- and 6-strand laid ropes shall be Z-twist (nght-hand lay), their strands S-twist and their roping yams Z-twist.
The 8-strand braided ropes shall consist of four S-twist strands and four Z-twist strands arranged so that S-twist strands alternate (individually or in pairs) with Z-twist strands (individually or in pairs).
The 12-strand braided ropes shall consist of six S-twist strands and six Z-twist strands arranged so that S-twist strands alternate (individually or in pairs) with Z-twist strands (individually or in pairs).
A double-braided rope shall consist of a number of strands that are braided to form a core, around which additional strands are braided to form a sheath. The core lies coaxially within the sheath. The number of strands varies, based upon the size of the rope.
A parallel rope construction consists of a number of sub-ropes protected by a non-load-bearing cover.
Each strand shall consist of an equal number of rope yarns sufficient to provide the characteristics spedfied in the International Standard for the relevant product. For ropes of reference number 36 or higher, the number of yarns in each strand may differ by one yarn or ±2.5 % from the intended number of yarns in the strand.
The ropes and their strands shall be continuous, without splice for standard delivered lengths or shorter lengths.ISO 9554 pdf free download.
