DANSK DSF/EN ISO 16148/PRA1 PDF

ISO 16148:2016 gives procedures for the use of acoustic emission examination (AT) and ultrasonic examination (UT) follow-up during the periodic inspection and testing of seamless steel cylinders and tubes with a water capacity of up to 3 000 l used for compressed and liquefied gases. This examination provides acoustic emission (AE) indications and locations that are evaluated by a secondary examination using UT for a possible flaw in the cylinder or tube. Methods other than UT for the secondary examination are not covered by this International Standard. ISO 16148:2016 does not cover composite cylinders. CAUTION ? Some of the tests specified in this International Standard involve the use of processes which could lead to a hazardous situation.
