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 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, Part 3. 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 elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 2559 was prepared by Technical Committee ISO/TC 61,Plastics, Subcommittee SC 13, Composites and reinforcement fibres. This fourth edition cancels and replaces the third edition (ISO 2559:1991), which has been technically revised. Annex A of this International Standard is for information only.

It is not applicable to surfacing mats, staple-fibre mats or glass mats (or bats) of the type used for thermal and acous- tic insulation. 2Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard.

Essentially, a specific mat is chosen so as to bring to the laminate its reinforcement properties 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 of standard- izing the conditions under which the mat is used (resin mix, cure system, laminate 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 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 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. 4.2Characteristic properties 4.2.1Resin compatibility The resin(s) recommended for use with the mat. 4.2.2Glass type The glass type as defined in ISO 2078. 4.2.3Filament diameter The 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.

Therefore the figure quoted is usually that of the input strand, the lin- ear density of which can only be determined by the mat manufacturer. 4.2.5Strand length The 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). NOTEThis International Standard covers only mats manufactured with strands made of continuous filaments and not mats made of discontinuous fibres. 4.2.6Size type The type of size (essentially the type of coupling agent) used to coat the filaments. 4.2.7Bonding system The system used to bond the strands, which may be either of a chemical type, which might be either a liquid binder (emulsion) of a solid binder (powder); or of a mechanical type, with or without carrier (if a carrier it is used, it shall be identified). 4.2.8Width The width of the mat, expressed in centimetres or millimetres. For mats with trimmed edges, the width may be deter- mined by the method given for woven fabrics in ISO 5025. For mats with untrimmed edges, the method given in annex A may be used. 4.2.9Edges The 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 vary. For such mats, the tolerances on the width shall be agreed upon between the interested parties. 4.2.10Length The 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 incorporates incomplete rolls. The number, the mass, or the minimum length of the incomplete rolls shall be specified. 4.2.11Degree of solubility of chopped-strand mat binder in styrene The solubility of the mat binder in styrene shall be determined in accordance with ISO 2558. It is generally expressed as high (), medium () or low (), depending on the result obtained using this method.200 s Licensed Copy: sheffieldun sheffieldun, na, Mon Nov 27 02:13:05 GMT+00:00 2006, Uncontrolled Copy, (c) BSI ISO 2559:2000(E) 4 4.3Controlled properties 4.3.1Mass per unit area The 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 carrier present. For each type of mat, the manufacturer shall give a nominal value of the mass per unit area and shall define the tol- erances on the measured values, specifying if the tolerances apply for the average of the test specimens taken across the width of the mat or to each test specimen. NOTEThe most common nominal values are,and. 4.3.2Percentage combustible matter The 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) applied 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, unless otherwise agreed upon between purchaser and supplier. 4.3.3Tensile strength The 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 tested. The type of test specimen to be used shall be stated in the specification. 4.3.4Thickness The thickness of the mat shall be determined in accordance with ISO 3616. 4.4Visual properties The mat shall be uniform in appearance. The roll shall be wound with appropriate compaction and the edges aligned 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 may exist in a mat, and which can occur dur- ing manufacture or during subsequent handling: tears; holes; dirt marks; grease spots; foreign matter; clumps of strands; clumps or strips of binder; dark strands; locally thin areas; 300 g/m2375 g/m2450 g/m2600 g/m2 Licensed Copy: sheffieldun sheffieldun, na, Mon Nov 27 02:13:05 GMT+00:00 2006, Uncontrolled Copy, (c) BSI ISO 2559:2000(E) 5 locally poorly bonded areas; irregular edges. The permissible number and extent of these and/or other visible non-conformities shall be agreed between the inter- ested parties. 5Designation The designation of the mat shall be up 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, and followed by coded informat
