When,where,why to use nondestructive testing methods

UT.This test sends sound waves through the material; when they hit a flaw (reflector) they bounce back to the transducer probe and are displayed on an oscilloscope monitor.The height and depth of the flaw then can be evaluated against standard calibration blocks for acceptance or rejection of the weld.When,where,why to use nondestructive testing methodsUT.This test sends sound waves through the material; when they hit a flaw (reflector) they bounce back to the transducer probe and are displayed on an oscilloscope monitor.The height and depth of the flaw then can be evaluated against standard calibration blocks for acceptance or rejection of the weld.Ultrasonic testing of austenitic and austenitic-ferritic Ultrasonic testing of ferritic and martensitic steel forgings is the subject of part 3 of this European Standard.2 Normative references This part of EN 10228 incorporates,by dated or undated reference,provisions from other publications.

Nonproprietary 'Integrity Evaluation of Indications in SI

WESTINGHOUSE CLASS 3 Two criteria for flaw acceptability are required by Section XI and they are 1) Acceptance Criteria based on Stress Intensity Factor (Section XI,IWB-3612).2) Acceptance Criteria based on Primary Stress Limits (Section XI,IWB-3610,which requires meeting the limits of Section III,NB 3000).These criteria are explained in the following sections,and will be used to Nondestructive Testing StandardsDetected flaws are evaluated for possible rejection due to nonconformance to set acceptance criteria.These nondestructive testing standards are instrumental to laboratories and a wide variety of industrial plants for examining a material's quality and,consequently,suitability for intended use.Non-destructive testing of steel forgings - Part 2 Non-destructive testing of steel forgings - Part 2 Penetrant testing (BS EN 10228-2:1998) 1 Scope This part of EN 10228 describes the method and acceptance criteria to
