Specifies a method of making test plates by wet compression moulding are defined. Using this method, test plates can be made in reproducible manner, making it possible to compare the results of tests carried out at different times and/or in different places. Test specimens cut from plates made by wet compression moulding are useful in characterizing the reinforcement used. Reinforcement can be either mats or fabrics. The following properties of these materials are of particular interest: water absorption (ISO 62); flexural strength and flexural modulus (ISO 178); impact strength (Charpy) (ISO 179); tensile strength, tensile modules and elongation at break (ISO 527-4). Intended to be used in conjunction with ISO 1268-1.
