1、Designation: E 2104 01Standard Practice forRadiographic Examination of Advanced Aero and TurbineMaterials and Components1This standard is issued under the fixed designation E 2104; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, th
2、e year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice establishes the minimum requirements forradiographic examination of metallic and nonmetallic
3、materialsand components used in designated applications such as gasturbine engines and flight structures.1.2 The requirements in this practice are intended to controlthe radiographic process to ensure the quality of radiographicimages produced for use in designated applications such as gasturbine en
4、gines and flight structures; this practice is notintended to establish acceptance criteria for material or com-ponents. When examination is performed in accordance withthis practice, engineering drawings, specifications or otherapplicable documents shall indicate the acceptance criteria.1.3 All area
5、s of this practice may be open to agreementbetween the cognizant engineering organization and the sup-plier, or specific direction from the cognizant engineeringorganization.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibil
6、ity of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.
