This part specifies in detail the criteria for compressive strength testing of synthetic Stone. Includes the terms and definitions of the test, principles, required instrumentation and equipment, specimen preparation, test procedures, test results and requirements for the test report. Applicable to the determination of the strength performance of synthetic Stone when subjected to pressure. The standard cites GB/T 35165 "Terms and Classification of Synthetic Stone" as the basis for terms and definitions, ensuring uniform understanding and application in the test process. The test evaluates the compressive performance of synthetic Stone by applying a uniformly distributed load to the specimen failure on the testing machine to verify its Reliability in engineering applications.
