36、(NDE) techniques have been successfully introduced as an alternative to the conventional testing procedures of gas cylinders, tubes and other cylinders at the time of periodic inspection and testing.One of the alternative NDE methods for certain applications is acoustic emission examination (AT), wh

37、ich has proved to be an acceptable test method applied during periodic inspection and testing in some countries.The test method requires pressurization to a level greater than the normal filling pressure.The pressurization medium can be either gas or liquid.Acoustic emission (AE) measurements are us

38、ed to detect and locate emission sources. Other NDE methods are needed to evaluate the significance of AE detected sources. One of the alternative NDE methods used as a follow-up to AT is ultrasonic examination (UT), which has proved to be an acceptable testing method applied during periodic inspect

39、ion and testing. The purpose of this International Standard is to provide a procedure for locating, detecting and evaluating the relevance of AE indications such as those from longitudinally oriented crack-like discontinuities. The shear wave (angle beam) UT method is intended to be used immediately

40、 following AT to evaluate the significance of AE indications.This International Standard describes two methods of AT, defined as Method A and Method B, and a method of follow-up UT.With the agreement of the testing and certifying body approved by the competent authority of the country of approval, t

41、he hydraulic pressure test of cylinders and tubes can be replaced by an equivalent AT/UT Method A or B.This International Standard is intended to be used under a variety of national regulatory regimes, but has been written so that it is suitable for the application of Reference.1Attention is drawn t

42、o requirements in the specified relevant national regulations of the country (countries) where the cylinders are intended to be used that might override the requirements given in this International Standard. Where there is any conflict between this International Standard and any applicable regulatio

43、n, the regulation always takes precedence.DIN EN ISO 16148:2016-09 EN ISO 16148:2016 (E) 5 1 ScopeThis 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 cyli

44、nders 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

45、 secondary examination are not covered by this International Standard.This International Standard 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.2 Normative referencesThe fol
