scope:

This standard describes the preparation of test plates made of unidirectionally orientated glass fibre or fabric and thermosetting resins by laying up and curing. The orientation of the reinforcement in each layer and the lay-up method shall be as given in the appropriate specification. These resins cure with or without loss of reaction products; in either case, their properties are not significantly altered. The resins can be processed at an elevated pressure agreed between the interested parties. The purpose of this standard is to standardize the preparation of the plates from which test specimens are subsequently machined. Standard specimens prepared in this manner may be used either for evaluating the components, i.e. the glass reinforcement, finishes, resins, catalysts, curing agents, etc., or for the quality control of the finished products.
