Scope

1.1 This practice covers the general principles to be followed for injection moulding test specimens of thermoplastics and gives details of mould designs for preparing specimen types for reference data, that is, for multipurpose-test specimens according to ISO 3167 (Specification D 5936) and for bars 80 mm 3 10 mm 3 4 mm. This practice provides a basis for establishing reproducible moulding conditions. This practice promotes uniformity in describing the various essential parameters of the moulding operation and also establishes a uniform practice in reporting moulding conditions. The special conditions required to prepare test specimens in a comparable and reproducible state will vary for each material used. These conditions are given in the ISO standard for the relevant material or are to be agreed upon between interested parties. NOTE 1—ISO round-robin tests with acrylonitrile/butadiene/styrene (ABS), styrene/butadiene (S/B) and polymethylmethacrylate (PMMA) showed that design of the mould is one of the important factors in preparation of test specimens. 1.2 This practice is identical to ISO 294-1. This standard is comparable to Practice D 3641 but neither standard should be substituted for the other. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
