scope:

This International Standard specifies the procedure for the preparation of test plates or panels by bonding glass cloth or mats with low-pressure thermosetting resins. In this International Standard the term "low-pressure thermosetting resins" relates to resins which cure at or above room temperature either without loss of reaction products or which are not significantly altered by loss of reaction products during cure and which can be processed with a pressure up to 3,5 MPa. The purpose of this International Standard is to standardize the preparation of the plates or panels from which test specimens subsequently are 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 verifying the overall quality of the finished "composite" products.
