DIN EN ISO 16148:2016-09

This International Standard 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. This International Standard does not cover composite cylinders. CAUTION - Some of the tests described in this standard involve the use of procedures that may result in a hazardous situation. This standard differs from DIN EN ISO 16148:2006-08 as follows: a) the scope has been extended to include tubes with a water capacity of up to 3 000 l used for compressed and liquefied gases; b) procedures for ultrasonic examination (UT) follow-up during periodic inspection, as described in the new Annex A (informative), have been added. The responsible German standardization committee is Working Committee NA 016-00-03 AA "Druckgasflaschen und Ausrüstung; Spiegelausschuss zu CEN/TC 23 und ISO/TC 58" ("Transportable gas cylinders and equipment; National mirror committee to CEN/TC 23 and ISO/TC 58") at DIN Standards Committee Pressurized Gas Installations (NDG).
