CEN/TC 249/SC 2/WG 1 - Reinforcements

ISO 1899:2009 specifies a method for the determination of the linear density of glass-fibre, carbon-fibre, aramid-fibre and any other reinforcement-fibre yarns.
It is applicable to all types of yarn, including single yarns, double and cabled yarns, textured yarns, rovings and staple-fibre yarns.

ISO 1890:2009 specifies a method for the determination of twist in yarns made from textile glass, carbon, aramid or any other reinforcement fibres.
The method applies to single yarns (one twist) and to folded or cabled yarns (two or more twists). For folded and cabled yarns, the method is generally applied only to the final twist step.
The International Standard is applicable to package-wound yarns. If the measurement is carried out on yarns taken from a beam (or warp) or from a fabric, the result is of an indicative nature only.
The method is not applicable to products made from staple fibres.

This European Standard specifies a method for the preparation of specimens of compression moulding composites for determining the anisotropy induced by material flow.
It is applicable to all SMC/BMC and GMT/LFT composites, which are being moulded under defined moulding conditions as described in EN ISO 12115 and ISO 1268-9.

ISO 9163:2005 specifies two methods for the determination of the tensile stress at break of an impregnated roving:
a reference method using test specimens produced with moulded 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 described for 1200 tex rovings only, which is the linear density that allows the roving to spread out most easily to give a flat tape.

If such additional properties are required they shall be determined in accordance with the test methods specified in EN 14118-2.

This part 3 of EN 14118 provides the technical specification for chopped strands and continuous filaments mats covered by the part 1.

This part of this European Standard gives a technical specification for rovings that are made from continuous filament textile glass. It defines those parameters which shall be specified plus other parameters which may be specified if required for a particular application or processing method.

1.3   The designation of a fabric is structured in a product hierarchy which includes several levels which determine families and sub-families of fabrics.
It is not intended that this hierarchy takes into account all the attributes of individual fabrics which may use different yarn types or different yarn counts. Neither is it intended to imply that woven fabrics having the same designation give necessarily the same performance.
This Part 1 of EN 13417 does not give engineering data, performance data or data which may be required to specify woven fabrics for a particular application or method of processing.

Therefore multi-axial multi-ply fabrics having the same designation do not give necessarily the same performance. This part 1 of EN 13473 does not give engineering data, performance data or data which may be required to specify multi-axial multi-ply fabrics for a particular application or method of processing. If such additional properties are required they have to be determined in accordance with the test methods specified in EN 13473-2.

This Part 2 of EN 13473 defines the test methods to be used to determine the designated and specified properties given in Parts 1 and 3 respectively.

requirements may be given in data block 3 (see clause 3).

This European Standard describes the designation system for yarns based on continuous filament textile glass (single yarns, folded yarns) and excludes textures yarns and yarns based on staple fibre, rovings and pre-impregnated yarns.

This European Standard specifies a method for the determination of the moisture content of reinfrocements products, such as continuous filament yarn, staple fibre yarn, rovings, chopped strands, mats, fabrics and other forms of reinforcements made form textile glass, carbon or aramid fibres.

This standard is applicable to high-performance, high modulus carbon fibre filament yarns as defined in material standards. The carbon fibre filament yarns are used for manufacturing semi-finished products and for reinforcing metallic, plastic and ceramic parts. Polyacrylonitrile, pitch or viscose filament yarns are used as precursor which are transformed into carbon fibre filament yarns by controlled pyrolysis.

This European Standard specified a method for the determination of the linear density of textile glass, carbon fibre and aramid fibre. It is applicable to all yarns including singles yarns, doubled and cabled, textured yarns, rovings and staple fibre yarns.

This European Standard specifies a method for the determination of twist in continuous filaments yarns made with textile glass, carbon or aramid. This method is not applicable to products made form staple fibres. For yarns without twist or with twist less than 10 T/m modified equipment is to be used in order to obtain the required precision (see paragraph 5.1).
