BS 2782-9 Met 902A:1992

This standard BS 2782-9 Met 902A:1992 Methods of testing plastics. Sampling and test specimen preparation.. Compression moulding test specimens of thermosetting materials is classified in these ICS categories:

• 83.080.10 Thermosetting materials

This International Standard specifies the general principles and the procedures to be followed for the preparation of test specimens from thermosetting compounds moulded under heat and pressure and for the establishment of comparable test reports from different testing organizations, it is applicable only to thermosetting materials based upon phenolics (ISO 800), aminoplastics (ISO 2112), melamine phenolics (ISO 4896), epoxides and unsaturated polyesters.

Because the properties of the specimens moulded from thermosetting materials depend on the conditions of preparation of the specimens, this International Standard also specifies the details of specimen preparation to be included with test reports of the properties of such specimens.

It may often be necessary to prepare specimens by special methods because of their composition, their flow properties or other variable factors. In this case, an agreement shall be made between the interested parties. The tables giving the specimen properties shall refer to these specific methods.
