12、 (the International Organization for Standardization) is a worldwide federation of national 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 com

13、mittee 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. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrot

14、echnical 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 International Standards. Draft International Standards adopted by the technical committees are circulated to the mem

15、ber 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 elements of this document may be the subject of patent rights. ISO shall not be held responsible for identify

16、ing any or all such patent rights. ISO 8516 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 13, Composites and reinforcement fibres. This second edition cancels and replaces the first edition (ISO 8516:1987), of which it constitutes a minor revision. The main changes are as

17、follows: a) the normative references have been updated; b) old Clause 3, which concerned sampling, has been deleted as it referred the reader to ISO 1886 which has been withdrawn; c) a terms and definitions clause has been added (new Clause 3); d) Clause 7 has been revised as two clauses (Clause 7,

18、“Delivery”, and Clause 8, “Storage”).

19、r folded yarns of textile glass. Textured glass yarns can be produced by several types of process. They can be made starting either from a single strand or from two or more strands in which one or more have been “opened” to give the “bulky” aspect of textured yarn. Textured glass yarn is used in var

20、ious applications, for example insulation, filtration, the manufacture of decorative textiles, the reinforcement of plastics and the manufacture of packing materials. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated reference

21、s, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

23、ons For the purposes of this document, the terms and definitions given in ISO 472 apply. 4 Designation The designation of the yarn shall conform to ISO 2078. BS ISO 8516:2011 ISO 8516:2011(E) 2 ISO 2011 All rights reserved5 Physical properties 5.1 General Unless otherwise agreed, textured glass yarn

24、s shall be defined by the characteristics specified in 5.2 to 5.7, and nominal values and tolerances shall be given for these characteristics in the suppliers technical specification. The criteria for acceptance or rejection of a batch, based on the results of testing, shall also be given in the sup

25、pliers specification. 5.2 Type of glass Various types of glass are used in the production of textured yarns. A list of available glass types is given in ISO 2078. 5.3 Size content The texturizing process requires the use of yarn covered with size to give suitable lubrication during texturization. Th

26、is size can be eliminated after weaving by a heat-cleaning treatment, if necessary. The size content shall be determined in accordance with ISO 1887. 5.4 Average filament diameter The average filament diameter shall be determined in accordance with ISO 1888. 5.5 Linear density The linear density sha

27、ll be determined in accordance with ISO 1889, taking care, when taking the test specimens, that the yarn is tensioned to a level suitable for staple-fibre yarns in order to ensure that the specimens will be of the required length. 5.6 Moisture content The moisture content shall be determined in acco

28、rdance with ISO 3344. 5.7 Breaking load At the yield point, textured yarn can possess a strength which is much less than the breaking load. If this is the case, the suppliers specification shall indicate the minimum value of the strength at yield and the minimum value of the breaking strength, as de

29、termined in accordance with ISO 3341.

30、 in 6.2 and 6.3). The acceptable level with regard to number or importance shall be agreed between supplier and buyer. If necessary, reference samples shall be kept by the supplier in order to assess any disputed packages, especially for the defects described in 6.2.3, 6.3.2, 6.3.3 and 6.3.10. 6.2 V

33、f texturization). 6.3.11 Dirty or incorrectly joined (or transferred) ends or unjoined ends (when joined ends were specified).

34、on and packaging of the yarn. 7.2 Labelling The specification shall include a requirement that the container holding the yarn packages be provided with an external label including the following information: the designation of the yarn; the type of yarn package or a code-number indicating the type; t

35、he type of container or a code-number indicating the type; the net mass of the yarn packages in the container; the name of the supplier; the date of manufacture. 8 Storage The specification shall include any requirements concerning the storage conditions (temperature, relative humidity, time) necess
