3、 the qualification of radiographic interpreters. The qualification of radio-graphic interpreters requires experience, knowledge, and skills unique to the interpretation of radiographic media andthe determination of acceptance criteria for weldments and adjacent base metal. Training and work experien

4、ce inradiographic theory, procedures, weld and adjacent base metal defect recognition, radiographic processing, handling,storage, and code requirements relating to radiographic acceptance criteria are essential to ensuring the competence ofindividuals engaged in radiographic interpretation.AWS B5.15

8、rds (codes, specifications, recommended practices, methods, classifications, and guides) of the AmericanWelding Society (AWS) are voluntary consensus standards that have been developed in accordance with the rules of theAmerican National Standards Institute (ANSI). When AWS American National Standar

9、ds are either incorporated in, ormade part of, documents that are included in federal or state laws and regulations, or the regulations of other govern-mental bodies, their provisions carry the full legal authority of the statute. In such cases, any changes in those AWSstandards must be approved by

In all cases, these standards carry the full legal authority of the contract or other documentthat invokes the AWS standards. Where this contractual relationship exists, changes in or devi

11、ations from requirementsof an AWS standard must be by agreement between the contracting parties.AWS American National Standards are developed through a consensus standards development process that bringstogether volunteers representing varied viewpoints and interests to achieve consensus.

26、ition was amended in 2007.The primary revision between the first edition and this edition is the addition of Subclause 10.2 on examination struc-ture. This specification now provides examinations subjects and weights for those examinations subjects. This changewas made in response to organizations a

27、nd companies who implemented the first edition in their personnel certificationand qualification. Revisions to the previous edition are underlined throughout the standard.The purpose of radiographic interpretation is to properly assess indications produced on radiographic media during theprocess of

28、weldment or adjacent base metal evaluation. The Radiographic Interpreter must be thoroughly familiar withthe process of radiography as well as the welding processes. This includes, but may not be limited to: welding processes,materials, limitation of various testing methods, drawings, procedures, sp

29、ecifications, behavior of different types ofradioactivity (particles and photons), film construction, behavior of energy sensitive imaging systems, mathematics,radiographic film selection, handling, and storage. For Radiographic Interpreters to be effective, they must not only betechnically competen

30、t, but also consistent and ethically principled in their dealings with clients and employers.Personnel seeking qualification to this specification should be prepared to receive instruction by their employers withregard to specific duties required for employment. In addition to the competence level a

31、nd areas specified herein, eachemployer must provide job orientation and/or training to ensure the competence of their employees.Comments and suggestions for the improvement of this standard are welcome.
