Scope: This standard specifies the concrete cube test method for testing prestressed concrete water pipes (vibration extrusion process and pipe core wire winding process), concrete and reinforced concrete drainage pipes (centrifugal, suspension roller, vertical extrusion and vertical vibration process). Test instruments and equipment, samples, test procedures, result calculation and evaluation, test reports, etc. for body compressive strength. Note: See Appendix A (Supplement) for the test method of compressive strength of concrete and reinforced concrete drainage pipe core samples. This standard is applicable to test the concrete compressive strength of prestressed concrete water pipes, concrete and reinforced concrete drainage pipes.
