The work of preparing International Standards is normally carrie
9、d out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. IS
10、O collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare Internatio
11、nal Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the ele
12、ments of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 1969 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 248, Textiles and textile products, in collaboration with
13、Technical Committee ISO/TC 38, Textiles, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). This third edition cancels and replaces the second edition (ISO 1969:1990), which has been technically revised. Copyright International Organization for Standard

26、 millimetres. b The linear density (in kilotex) corresponds to the net mass per length of the rope, expressed in grams per metre or in kilograms per thousand metres. c The linear density is under reference tension and is measured as specified in ISO 2307. d The breaking forces quoted above relate to
27、 new dry and wet ropes. d Minimum values stated in individual standards shall be reduced by 10 % in the case of a rope with eye-spliced terminations. f A force determined by the test methods as specified in ISO 2307 is not necessarily an accurate indication of the force at which that rope might brea
28、k in other circumstances and situations. Type and quality of termination rate of force application, prior conditioning and previous force applications to the rope can significantly influence the breaking force. A rope bent around a post, capstan, pulley or sheave might break at a significantly lower
29、 force. A knot or other distortion in a rope might significantly reduce the breaking force.
