59.100 - Materials for the reinforcement of composites

This document specifies four methods for the determination of the density of carbon fibre tested as a yarn: — method A: liquid-displacement method; — method B: sink/float method; — method C: density-gradient column method; — method D: gas pycnometer method. Method C is the reference method in cases of dispute, etc.

This document specifies five test methods used for the determination of the diameter and cross-sectional area of single carbon fibre filaments. The shape of the cross-section of the filaments from different suppliers can vary significantly. The term "diameter" used in this document applies to all cases, from a "true" diameter, where the filament is exactly circular in cross-section, to an "apparent" diameter where the filament is not circular. The methods proposed are not necessarily directly ap...view more

ISO 2797:2017 establishes a basis for a specification for textile glass rovings, whether direct rovings or assembled rovings.

ISO 5025:2017 specifies a method for determining the width and length of a woven-fabric reinforcement in the form of a roll[1] . [1] Attention is drawn to ISO 22198 which is a related International Standard dealing with textiles.

ISO 30012:2016 specifies test methods for measurement of the size and aspect ratio of crushed carbon-fibre-reinforced plastics (CFRP), especially for recycling purpose. In this International Standard the shape of crushed CFRP, the fragment, is treated as a rectangular shape, and the measurement of the long and short sides of the shape is described. It applies to fragments of the following average dimensions: - length of the long side: 5 mm to 50 mm; - width of the short side: 1 mm to 10 mm. ISO ...view more

ISO 1887:2014 specifies a method for the determination of the combustible-matter content of products made from textile glass, such as continuous-filament yarns, staple-fibre yarns, rovings, chopped strands, milled fibres, fabrics, chopped-strand and continuous-filament mats, and other glass reinforcements.

ISO 10122:2014 provides a basis for specifications applicable to tubular braided sleeves used as reinforcements in plastics. It deals with tubular sleeves braided from all types of yarn or roving.

ISO 13931:2013 specifies two methods (i.e. method A and method B) for the determination of the volume resistivity of carbon fibre.

ISO 3342:2011 specifies a method for the determination of the tensile breaking force of textile glass mats. The method is intended for chopped-strand mat but is equally applicable to certain types of continuous-strand mat usually intended for pultrusion.

ISO 2559:2011 provides a basis for specifications which is applicable only to textile glass mats that are made from chopped or continuous strands bonded together by chemical or mechanical means and that are used for the reinforcement of plastics. It is not applicable to surfacing mats, staple-fibre mats or glass mats (or bats) of the type used for thermal and acoustic insulation.

ISO 4604:2011 specifies a method of determining the conventional flexural stiffness of reinforcement fabrics by means of a fixed-angle flexometer. This method is not suitable for testing fabrics that are limp or that have a marked tendency to curl or twist or fray.

ISO 1043-2:2011 specifies uniform symbols for terms referring to fillers and reinforcing materials. It includes only those symbols that have come into established use, and its main aim is both to prevent the occurrence of more than one symbol for a given filler or reinforcing material and to prevent a given symbol being interpreted in more than one way.

ISO 4900:2011 specifies a method for the determination of the contact mouldability of textile glass mats and fabrics. NOTE The hand lay-up method of moulding is generally not regarded as lending itself to objective determinations. However, if the process is carried out by the same operator, useful comparisons can be drawn between results obtained with different mats or fabrics.

ISO 3598:2011 provides a basis for a specification applicable to textile glass yarns (strands, slivers, single yarns, folded yarns and cable yarns). It does not apply to textured yarns, rovings, chopped strands, milled fibres, pre-impregnated yarns, etc. It does not cover all requirements for specialized applications. Where such other requirements are necessary, they are, or will be, given in other appropriate International Standards.
