The GB/T 2832-1996 standard provides specifications for the determination of the external pressure strength of pottery pipes. It specifies the equipment required for the test, including loading devices, etc.; standardizes the preparation process of pottery pipe samples; specifies the loading rate, test steps and result calculation methods. Testing according to this standard can accurately evaluate the ability of pottery pipes to resist external pressure, provide a key basis for pottery pipe mass testing and engineering material selection, and is widely used in pottery pipe production, construction engineering and other fields to ensure that pottery pipes can withstand corresponding external pressure in actual use.
