This part of ISO 1268 specifies a method of making test plates by wet compression moulding. Using this method, test plates can be made in a 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. The 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 modulus and elongation at break (ISO 527-4).

This part of ISO 1268 is intended to be used in conjunction with ISO 1268-1.
