GB/T 39812-2021 Plastics—Preparation of test specimens by machining
Abstract
This standard specifies the general principles and methods for preparing samples and making incisions on plastic samples formed by compression molding and injection molding, extruded sheets, and semi-finished or finished plates through machining. To obtain reproducible machining and notch processing conditions, the following standard conditions shall be followed: When there are relevant material specifications or standards stipulating specific test methods, the tests shall be conducted in accordance with the relevant material specifications or specific test method standards. If there are no specific operating procedures, the operating conditions of the key parts shall be determined by agreement between the relevant parties.
