How to test for DOT 406 compliance
DOT 406 compliance test is an essential part of making the certification documents. This test mainly includes pressure test, material thickness test and other advanced level tests such as hydrostatic and pneumatic tests.

Pressure test: The MAWP (Maximum allowable working pressure) of each tank trailer must be no lower than 2.65 psi and no higher than 4 psi. Pressure tests are a non-harmful way to assure the integrity of the tank trailer. The piping codes demand that a piping system is to be strong to sustain its rated pressure and has no leaks. The ASME B31 Pressure Piping Code is the most extensively used code for pressure and leak testing.

Material thickness test: This test identifies the quality and the thickness of the material that is used in the construction of the tank trailer. Therefore, material thickness is required to fulfil the equivalent DOT406 specification’s structural strength and accident damage standards.

Hydrostatic and pneumatic tests are the advanced level pressure testing of tank trailers which are done by the manufacturers, once the trailers are over with the typical testings……. Read more
