1.1 这种做法 2. 涵盖了金属和非金属材料射线照相检查的最低要求。 1.2 适用性-- 本规程中的射线照相检验标准适用于所有类型的金属和非金属材料。如有规定，可用于金属或非金属材料、焊接件、铸件和钎焊材料的射线照相检查。本规程中表达的要求旨在控制射线照相图像的质量，而不是旨在建立零件和材料的验收标准。 1.3 应用基础-- 在这一实践中，有些领域可能需要认可的工程组织和供应商之间达成协议，或认可的工程机构的具体指导。 这些项目应在采购订单或合同中说明。 1.3.1 国防部合同。 1.3.2 人员资格， 5.1.1 . 1.3.3 代理资格， 5.1.2 . 1.3.4 数字化技术， 5.4.5 . 1.3.5 替代图像质量指示器（IQI）类型， 5.5.3 . 1.3.6 检查顺序， 6.6 . 1.3.7 非膜技术， 6.7 . 1.3.8 射线照相质量水平， 6.9 . 1.3.9 光密度， 6.10 . 1.3.10 IQI资格暴露， 6.13.3 . 1.3.11 不要求像质计， 6.18 . 1.3.12 焊缝的检查范围， A2.2.2 . 1.3.13 电子束焊接， A2.3 . 1.3.14 几何不清晰度， 6.23 . 1.3.15 检查责任， 6.27.1 . 1.3.16 检查报告， 6.27.2 . 1.3.17 射线照片的保留， 6.27.8 . 1.3.18 射线照片的储存， 6.27.9 . 1.3.19 射线照片的复制， 6.27.10 和 6.27.10.1 . 1.3.20 可接受的零件， 6.28.1 . 1.4 单位-- 以国际单位制或英寸磅单位表示的数值应单独视为标准。每个系统中规定的值可能不是完全相等的；因此，每个系统应独立使用。将两个系统的值合并可能导致不符合标准。 1.5 本标准并不旨在解决与其使用相关的所有安全问题（如有）。 本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 4.1 本规程为射线照相方法的应用和控制确定了基本参数。 编写本规程是为了在工程图纸、规范或合同中进行规定。这不是无损检测设施使用的详细操作程序，因此必须通过详细程序进行补充（见 6.1 ). 实践 E1030/E1030M , E1032 和 E1416 包含有助于制定详细技术/程序要求的信息。

1.1 This practice 2 covers the minimum requirements for radiographic examination for metallic and nonmetallic materials. 1.2 Applicability— The criteria for the radiographic examination in this practice are applicable to all types of metallic and nonmetallic materials. When specified, it may be used for radiographic inspection of metallic or non-metallic materials, weldments, castings, and brazed materials. The requirements expressed in this practice are intended to control the quality of the radiographic images and are not intended to establish acceptance criteria for parts and materials. 1.3 Basis of Application— There are areas in this practice that may require agreement between the cognizant engineering organization and the supplier, or specific direction from the cognizant engineering organization. These items should be addressed in the purchase order or the contract. 1.3.1 DoD contracts. 1.3.2 Personnel qualification, 5.1.1 . 1.3.3 Agency qualification, 5.1.2 . 1.3.4 Digitizing techniques, 5.4.5 . 1.3.5 Alternate image quality indicator (IQI) types, 5.5.3 . 1.3.6 Examination sequence, 6.6 . 1.3.7 Non-film techniques, 6.7 . 1.3.8 Radiographic quality levels, 6.9 . 1.3.9 Optical density, 6.10 . 1.3.10 IQI qualification exposure, 6.13.3 . 1.3.11 Non-requirement for IQI, 6.18 . 1.3.12 Examination coverage for welds, A2.2.2 . 1.3.13 Electron beam welds, A2.3 . 1.3.14 Geometric unsharpness, 6.23 . 1.3.15 Responsibility for examination, 6.27.1 . 1.3.16 Examination report, 6.27.2 . 1.3.17 Retention of radiographs, 6.27.8 . 1.3.18 Storage of radiographs, 6.27.9 . 1.3.19 Reproduction of radiographs, 6.27.10 and 6.27.10.1 . 1.3.20 Acceptable parts, 6.28.1 . 1.4 Units— The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 This practice establishes the basic parameters for the application and control of the radiographic method. This practice is written so it can be specified on the engineering drawing, specification, or contract. It is not a detailed how-to procedure to be used by the NDT facility and, therefore, must be supplemented by a detailed procedure (see 6.1 ). Practices E1030/E1030M , E1032 , and E1416 contain information to help develop detailed technique/procedure requirements.
