    Scope - (Show below) - (Hide below)

    1.1 This practice covers the general principles to be followed when injection molding test specimens of thermoplastic molding and extrusion materials. This practice is to be used to obtain uniformity in methods of describing the various steps of the injection molding process and to set up uniform methods of reporting these conditions. The exact conditions required to prepare suitable specimens will vary for each plastic material. Those conditions shall become a part of the specification for the material, or be agreed upon between the purchaser and the supplier. Any requirements or recommendations in the material specification which differ from this standard take precedence over those in this standard.

    1.2 The methodology presented assumes the use of reciprocating screw injection molding machines.

    1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

    1.4 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.

    Note 1—This practice is equivalent to the following parts of ISO 294: PlasticsInjection Moulding of Test Specimens of Thermoplastic Materials; 294-1: Part 1General Principles and Multipurpose Test Specimens (ISO Type A Mould) and Bars (ISO Type B Mould); ISO 294-2: Part 2Small Tensile Bars (ISO Type C Mould); ISO 294-3: Part 3Plates (ISO Type D Moulds).
