8、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 organizations, governmental
9、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 given in the ISO/IEC Directives
10、, 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 least 75 % of the member bodies cas

Essentially, a specific mat is chosen so as to bring to the laminate its reinforcement properties
21、under certain environmental conditions, which may range from a dry inert to a wet corrosive atmosphere.The expected product performance properties are generally not guaranteed as such due to the difficulty in standardizing the conditions under which the mat is used (resin mix, cure system, laminate
22、structure, glass/resin/filler ratio, etc.). For this reason, the mat will be characterized in the specification by other guaranteed properties which can be correlated with the desired practical laminating properties. The latter can be divided into characteristic, controlled and visual properties, as
23、 defined in Clause 3.Where required, the controlled properties (measured parameters) may be stated on certificates of conformity or other quality control test reports.The following is a proposed list of “characteristic” and “controlled” properties with, when applicable, the relevant test method. The
24、 distinction between characteristic and controlled properties is indicative only, and may vary for different mat products.The specification for a given mat shall include the relevant properties among those listed hereafter, with tolerances where applicable.4.2 Characteristic properties4.2.1 Resin co
25、mpatibilityThe resin(s) recommended for use with the mat.4.2.2 Glass typeThe glass type as defined in ISO 2078.4.2.3 Filament diameterThe average diameter of the filaments constituting the strands in the mat. If necessary, the average filament diameter may be determined in accordance with ISO 1888.4
26、.2.4 Strand linear densityIt is not normally possible to determine the linear density of the strands in the mat since they might have been split and/or chopped during the production process. Therefore the figure quoted is usually that of the input strand, the linear density of which can only be dete
27、rmined by the mat manufacturer.4.2.5 Strand lengthThe length of the strands, which may be either unchopped (continuous-filament mat) or chopped to a given length, with the possibility of a mix of different specified lengths (chopped-strand mat).4.2.6 Size typeThe type of size (essentially the type o
28、f coupling agent) used to coat the filaments.4.2.7 Bonding systemThe system used to bond the strands, which may be either of a chemical type, e.g. a liquid binder (emulsion) or a solid binder (powder),ISO 2559:2011(E)2 ISO 2011 All rights reservedBS ISO 2559:2011 or of a mechanical type, with or wit
29、hout carrier (if a carrier is used, it shall be identified).4.2.8 WidthThe width of the mat, expressed in centimetres or millimetres. For mats with trimmed edges, the width may be determined by the method given for woven fabrics in ISO 5025. For mats with untrimmed edges, the method given in Annex A
30、 may be used.4.2.9 EdgesThe nature of the edges of the mat, which may be either untrimmed (feathered) on one or both sides; or trimmed on both sides.In the case of mats untrimmed along one or both edges, the width shall be measured between two points where the thickness of the mat does not visibly v
31、ary. For such mats, the tolerances on the width shall be agreed upon between the interested parties.4.2.10 LengthThe length of the material in a roll. The specification may allow the length to vary between rolls or to be fixed within agreed tolerances. Moreover, it is possible that a shipment incorp
32、orates incomplete rolls. The number, the mass or the minimum length of the incomplete rolls shall be specified.4.2.11 Degree of solubility of chopped-strand mat binder in styreneThe solubility of the mat binder in styrene shall be determined in accordance with ISO 2558. It is generally expressed as
33、high (200 s), depending on the result obtained using this method.4.3 Controlled properties4.3.1 Mass per unit areaThe mass per unit area shall be determined in accordance with ISO 3374 and expressed in grams per square metre. This mass includes the glass strands, the size and the binder(s) plus any
34、carrier present.For each type of mat, the manufacturer shall give a nominal value of the mass per unit area and shall define the tolerances on the measured values, specifying if the tolerances apply to the average of the test specimens taken across the width of the mat or to each test specimen.NOTE
35、The most common nominal values are 300 g/m2, 375 g/m2, 450 g/m2and 600 g/m2.4.3.2 Percentage combustible matterThe percentage of combustible matter shall be determined in accordance with ISO 1887. The combustible matter corresponds to the sum of the size applied to the filaments and the binder(s) ap
36、plied to the strands. In the case of mats bonded mechanically with an organic-fibre carrier, the mass of the carrier would be included in the combustible-matter content.The tolerances given in the specification shall be related to the average for test specimens taken across the width of the mat, unl
37、ess otherwise agreed upon between purchaser and supplier.ISO 2559:2011(E) ISO 2011 All rights reserved 3BS ISO 2559:20114.3.3 Tensile strengthThe dry tensile strength of the mat shall be determined in accordance with ISO 3342, which includes two types of specimen depending on the type of mat being t
38、ested. The type of test specimen to be used shall be stated in the specification.4.3.4 ThicknessThe thickness of the mat shall be determined in accordance with ISO 3616.4.4 Visual propertiesThe mat shall be uniform in appearance. The roll shall be wound with appropriate compaction and the edges alig
39、ned so that telescoping does not exceed a given tolerance, agreed between purchaser and supplier.Listed below are a number of recognized visible non-conformities which might exist in a mat, and which can occur during manufacture or during subsequent handling: tears; holes; dirt marks; grease spots;
40、foreign matter; clumps of strands; clumps or strips of binder; dark strands; locally thin areas; locally poorly bonded areas; irregular edges.The permissible number and extent of these and/or other visible non-conformities shall be agreed between the interested parties.5 DesignationThe designation o
41、f the mat shall be one of the following elements: Block 1: mat type (chopped strand or continuous filament). Block 2: mass per unit area, width. Block 3: binder type (powder or emulsion), strand length(s) and tex.This designation is generally preceded by the commercial name given by the manufacturer
42、 and followed by coded information concerning the trimmed edges or any other information specific to the relevant mat.6 LabellingEach roll of mat and each pallet shall bear a label indicating the manufacturers name, the type of mat and any data needed to ensure material traceability (such as roll nu
43、mber, mass, length or production date).ISO 2559:2011(E)4 ISO 2011 All rights reservedBS ISO 2559:20117 Sampling and conditioningSelect, from each delivery of a given type of mat, a suitable number of rolls. Unroll the outer layer of each roll selected, ensuring that any damaged sections are removed.
44、 Then take, from the whole width, a laboratory sample of sufficient length to enable all the required test specimens to be cut out, as specified in the applicable test methods.Condition the laboratory sample for at least 1 h in one of the standard atmospheres specified in ISO 291, unless another atm
45、osphere is required by the particular nature of the product.8 Presentation, packaging and storage conditionsRequirements concerning the presentation, packaging and storage conditions shall be given.ISO 2559:2011(E) ISO 2011 All rights reserved 5BS ISO 2559:2011Annex A (informative) Determination of
