Glass reinforced plastics - Measurement of hardness by means of a Barcol impressor
This Europeann Standard describes the determination of indentation hardness of glass reinforced plastics materials using a Barcol Impressor, Model No 934-1.
Note : The Barcol impressor is portable and therefore suitable for testing the hardness of fabricated parts and individual test specimens for production control purposes.

1.1 This document specifies methods for determining the compressive properties, in directions
parallel to the plane of lamination, of fibre-reinforced plastic composites, based on thermosetting or
thermoplastic matrices. The compressive properties are of interest for specifications and qualitycontrol
purposes. The test specimens are machined from a flat test plate, or from suitable finished or
semi-finished products.
1.2 Two loading methods and two types of specimen are described.
The loading methods are:
— Method 1: provides shear loading of the specimen (gauge length unsupported)
— Method 2: provides combined loading of the specimen (gauge length unsupported)
NOTE For tabbed specimens loaded using method 2, load is transferred through a combination of endloading
and shear-loading through the tabs.
The specimen designs are:
— Type A specimen: rectangular cross-section, fixed thickness, end-tabbed (mainly for aerospace
style preimpregnates (~ 0,125 mm ply thickness)
— Type B specimen: rectangular cross-section, range of thicknesses, untabbed or end-tabbed, two
specimen sizes are available (B1 and B2).
The Type A specimen is used for unidirectionally or biaxially reinforced materials tested in the
fibre direction, where the fibres are normally either aligned continuous or aligned long (>7,5 mm)
discontinuous. The Type B1 and B2 specimens are used for multi-directional aligned; mat, fabric and
other multi-directionally reinforced materials where the fibre structure is more complex and/or
coarser.
1.3 This document gives criteria for checking that the combination of test method and specimen
design result in valid failures. It is noted that alternative test method/specimen combinations will not
necessarily give the same result.
1.4 The methods specify required dimensions for the specimen. Tests carried out on specimens of
other dimensions, or on specimens that are prepared under different conditions, can produce results
that are not comparable. Other factors, such as the speed of testing, the support fixture used and the
conditioning of the specimens, can influence the results.

This document specifies two calcination methods for the determination of the textile glass and mineral filler content of glass-reinforced plastics:
— Method A: for the determination of the textile glass content when no mineral fillers are present.
— Method B: for the determination of the textile-glass and mineral-filler content when both components are present.
This document is applicable to the following types of material:
— prepregs made from yarns, rovings, tapes or fabrics;
— SMC, BMC and DMC moulding compounds;
— textile-glass-reinforced thermoplastic moulding materials and granules;
— filled or unfilled textile-glass laminates made with thermosetting or thermoplastic resins.
The methods do not apply to the following types of reinforced plastic:
— those containing reinforcements other than textile glass;
— those containing materials which do not completely burn off at the test temperature (for example, those based on silicone resin);
— those containing mineral fillers which degrade at temperatures below the minimum calcination temperature.

This document specifies the test conditions for the determination of the tensile properties of isotropic and orthotropic fibre-reinforced plastic composites, based upon the general principles given in ISO 527-1.
NOTE 1 Unidirectional reinforced materials are covered by ISO 527-5.
The methods are used to investigate the tensile behaviour of the test specimens and for determining the tensile strength, tensile modulus, Poisson's ratios and other aspects of the tensile stress-strain relationship under the defined conditions.
The test method is suitable for use with the following materials:
— fibre-reinforced thermosetting and thermoplastic composites incorporating non-unidirectional reinforcements such as mats, woven fabrics, woven rovings, chopped strands, combinations of such reinforcements, hybrids, rovings, short or milled fibres or preimpregnated materials (prepregs);
NOTE 2 Injection moulded specimens are covered by ISO 527-2.
— combinations of the above with unidirectional reinforcements and multidirectional reinforced materials constructed from unidirectional layers, provided such laminates are symmetrical;
NOTE 3 Materials with completely or mainly unidirectional reinforcements are covered by ISO 527-5.
— finished products made from materials mentioned above.
The reinforcement fibres covered include glass fibres, carbon fibres, aramid fibres and other similar fibres.

This document specifies the test conditions for the determination of the tensile properties of unidirectional fibre-reinforced plastic composites, based upon the general principles given in ISO 527-1.
NOTE Isotropic and orthotropic reinforced materials are covered by ISO 527-4.
The methods are used to investigate the tensile behaviour of the test specimens and for determining the tensile strength, tensile modulus, Poisson's ratios and other aspects of the tensile stress-strain relationship under the conditions defined.
The test method is suitable for all polymer matrix systems reinforced with unidirectional fibres and which meet the requirements, including failure mode, set out in this document.
The method is suitable for composites with either thermoplastic or thermosetting matrices, including preimpregnated materials (prepregs). The reinforcements covered include carbon fibres, glass fibres, aramid fibres and other similar fibres. The reinforcement geometries covered include unidirectional (i.e. completely aligned) fibres and rovings and unidirectional fabrics and tapes.
The method is not normally suitable for multidirectional materials composed of several unidirectional layers at different angles (see ISO 527-4).

This document specifies a method for the determination of the mass per unit area. It also specifies five methods (Method A to Method E) for the determination of the fibre mass per unit area of moulding compounds and prepregs. The five methods are as follows:
— Method A: Extraction by Soxhlet;
— Method B: Extraction by immersion in solvent in a beaker;
— Method C: Decomposition by loss ignition;
— Method D: Extraction by wet combustion;
— Method E: Method by calculation.
This document is applicable to the following types of materials:
— moulding compound and preimpregnated unidirectional sheet, tape, fabric and mats;
— prepregs in which any type of reinforcement (aramid, carbon, glass, etc.) and any type of matrix (thermosetting or thermoplastic) has been used.
Typically, reinforcement fibres are coated with sizing or finishes. These normally dissolve with the resin and are, therefore, included in the resin content.
This document is not applicable to the following types of prepregs:
— those containing reinforcements which are soluble (or partly soluble) in the solvents used to dissolve the resin.

ISO 10350 identifies specific test procedures for the acquisition and presentation of comparable data for certain basic properties of plastics. In general, each property is specified by a single experimental value, although in certain cases properties are represented by two values obtained under different test conditions or along different directions in the material. The properties included are those presented conventionally in manufacturers' data sheets.
This document applies to reinforced thermoplastic and thermosetting materials where the reinforcement fibres are either discontinuous with a fibre length prior to processing greater than 7,5 mm or continuous (e.g. fabric, continuous-strand mat or unidirectional).
ISO 10350-1 deals specifically with unreinforced and filled plastics, including those using fibres less than 7,5 mm in length.

This document specifies a method using a shear test apparatus for measuring the in-plane shear stress/shear strain response, shear modulus and shear strength of continuous-fibre-reinforced plastic composite materials with fibre orientations of 0° and 0°/90°.
This method is applicable to thermoset and thermoplastic matrix laminates made from unidirectional layers/non-woven fabrics and/or fabrics including unidirectional fabrics, with the fibres oriented at 0° and 0°/90° to the specimen axis, where the lay-up is symmetrical and balanced about the specimen mid-plane.
The method is suitable for determining shear properties in both the linear and nonlinear load-deformation range even at shear strains greater than 5 %.
Short and long fibre-reinforced plastic composites can also be tested using this document.
