ISO 16148:2006 is a guideline for using acoustic emission testing (AT) during re-qualification of seamless steel cylinders and tubes of water capacity up to 3 000 l used for compressed and liquefied gases. For cylinders below 20 l additional precautions may be taken due to the potential reflections from the ends. This test provides indications and locations that should be evaluated by another test for a possible flaw in the cylinder. ISO 16148:2006 covers monolithic steel cylinders.
