Gives the general principles to be followed when injection moulding test specimens of thermosetting powder moulding compounds (PMCs) and gives details of mould designs for the preparation of one type of specimen for use in establishing reproducible moulding conditions. The aim is to promote uniformity in describing the main parameters of the moulding process and to establish also, a uniform practice in reporting moulding conditions.
