This publication identifies tests that are used to qualify characteristics of certain compressed gas cylinders. It is not the intent to qualify the value or merit of these tests but to make the reader aware of these tests.
Some tests are required by the U.S. Department of Transportation (DOT) and/or Transport Canada (TC) regulations, which will also specify when such tests are performed. Some tests relating to specific cylinder service or usage such as environmental tests are beyond the scope of this publication.
Tests described in this publication are not intended to be the only ones applicable to every cylinder, gas service, or usage. Additional tests could be required to satisfy specific areas of need.
This publication does not address testing for composite cylinders and cylinders manufactured to DOT special permits and/or TC equivalency certificates. This publication does not address all testing requirements for acetylene and cryogenic cylinders; however, some tests could apply (for example, mechanical testing, proof pressure testing, hydrostatic testing) for shells of these cylinders.
