25、standards bodies (ISO member bodies). The work of preparing International Standards is normally carried 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

26、 organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules g

27、iven in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International 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 leas

28、t 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements 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 9163 was prepared by Technical Committee ISO/TC 61, P

29、lastics, Subcommittee SC 13, Composites and reinforcement fibres. This second edition cancels and replaces the first edition (ISO 9163:1996), which has been technically revised, as follows: The reference method remains essentially the same, with a few corrections, as in ISO 9163:1996. The so-called

30、“fast method” described in ISO 9163:1996 has been deleted because it was no longer used. It has been replaced by a method which needs far less time and gives results consistent with the reference method.

32、ded epoxy tabs; a short method using test specimens with no tabs or simple cardboard or composite tabs. The methods are applicable to both assembled (multistrand) and direct (multifilament) rovings; nevertheless the reference method may be used for various linear densities, but the short method is d

33、escribed for 1 200 tex rovings only, which is the linear density that allows the fibres in the roving to spread out most easily during impregnation. 2 Normative references The following referenced documents are indispensable for the application of this document.
