ASTM D2412 is a standard test method used for determining the external loading characteristics of plastic pipe through parallel-plate loading. This method is primarily used to evaluate the pipe’s stiffness, stiffness factor, and the load required at specific levels of deflection. The results help assess how well plastic pipes perform under compressive loads.

For more detailed information about this test method, including equipment requirements and procedures, please refer to the official documentation available on the  ASTM website.
