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. 2 Normative references The following referenced documents are indispensable for the application of this document.

BS EN ISO 9554:2010 pdf free download.Fibre ropes – General specifications (ISO 9554:2010). 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 yams sufficient to provide the characteristics specified in the International Standard for the relevant product. For ropes of reference number 36 or higher, the number of yams in…

BS EN ISO 2307:2010 pdf free download.Fibre ropes – Determination of certain physical and mechanical properties (ISO 2307:2010). The linear density, lay length and braided pitch are measured with the rope under a specified tension called the reference tension, as specified in Annex A. The elongation corresponds to the measured increase in length of the rope when the tension to which it is subjected is increased from an initial value (reference tension) to a value equal to 50 % of the minimum specified breaking strength of the rope. The breaking force is the maximum force registered (or reached) during a breaking test on the test piece, carried out on a tensile testing machine with constant rate of traverse of the moving element. The breaking force values given in the tables of rope specifications are only valid when this type of testing machine is used. When it is not possible to test the whole section of rope, the method described in Annex B can be used, subject to agreement between the parties involved. This International Standard also provides a method for measuring water repellency, lubrication and finish content, and heat setting treatment, when requested by the customer. 2 Normative references The…
