JIS K 7152:1995

This Japanese Industrial Standard specifies the general principles to be followed when injection moulding test specimens of thermoplastic materials. It describes two preferred mould designs and gives examples of other acceptable mould designs. It provides a basis for establishing reproducible moulding conditions. Its purpose is to promote uniformity in describing the essential moulding parameters and also to establish uniform practice in reporting moulding conditions. The exact conditions required to prepare specimens in a defined, reproducible state will vary for each material, mould and machine used. These conditions shall be agreed upon between interested parties unless they are part of an International Standard for the relevant material.
