Scope

This part of GB/T 24148 specifies the test methods used for the preparation of unsaturated polyester resin samples and the determination of their properties. Specifies the handling requirements for the test material, as well as the conditioning of the test material before molding and the test specimen before testing. The properties of crosslinked unsaturated polyester resins can be selected from the general test methods of ISO 10350-1:1998. This section also includes test methods widely used for unsaturated polyester resins or other test methods of special significance (for special properties of uncrosslinked resin molding). In order to obtain repeatable and comparable test results, the test methods, sample preparation, conditioning procedures and specimen dimensions specified in this standard must be used. For products based on unsaturated polyester resin, other existing standards related to performance measurement and sample preparation can be used as reference.
