4、ommittee on NondestructiveTesting.These nondestructive testing(NDT)methods include:acoustic emission,electromagnetic testing,gamma-andX-radiology,leak testing,liquid penetrant testing,magneticparticle testing,neutron radiology and gauging,ultrasonictesting,and other technical methods.1.2 Committee E
5、07 recognizes that the terms examination,testing and inspection are commonly used as synonyms innondestructive testing.For uniformity and consistency in E07nondestructive testing standards,Committee E07 encouragesthe use of the term examination and its derivatives whendescribing the application of n
6、ondestructive test methods.There are,however,appropriate exceptions when the term testand its derivatives may be used to describe the application ofa nondestructive test,such as measurements which produce anumeric result(for example,when using the leak testingmethod to perform a leak test on a compo
7、nent,or an ultrasonicmeasurement of velocity).Additionally,the term test should beused when referring to the NDT method,that is,RadiologicTesting(RT),Ultrasonic Testing(UT),and so forth.(Example:Radiologic Testing(RT)is often used to examine material todetect internal discontinuities.)1.3 Section A
8、defines terms that are common to multipleNDT methods,whereas,the subsequent sections define termspertaining to specific NDT methods.1.4 As shown on the chart below,when nondestructivetesting produces an indication,the indication is subject tointerpretation as false,nonrelevant or relevant.If it has
9、beeninterpreted as relevant,the necessary subsequent evaluationwill result in the decision to accept or reject the material.Withthe exception of accept and reject,which retain the meaningfound in most dictionaries,all the words used in the chart aredefined in Section A.1This terminology is under the
