1.1 本规程涵盖了铸件射线检查的统一程序。焊接件的射线检查可在 416欧元 。 1.2 该实践仅适用于放射检查，其中图像最终显示在显示屏（监视器）上进行评估。测试部件验收可以基于静态或动态图像。检查结果可能会被记录下来以备日后审查。这种做法不适用于由计算机自动进行评估的全自动系统。 1.3 由于铸件固有的许多复杂几何形状和零件配置，有必要认识到与获得完整的射线透视覆盖相关的潜在限制。 应考虑几何结构或零件配置不允许完全辐射覆盖的区域。 1.4 以英寸磅为单位的数值应视为标准。括号中给出的国际单位制仅供参考。 1.5 本标准并非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 本实践中的要求旨在控制放射图像的质量，以产生令人满意和一致的结果。这种做法不是为了控制铸件的可接受性。射线透视法可用于检测本实践灵敏度范围内的体积不连续性和密度变化。射线透视的动态方面有助于最大限度地提高缺陷响应。

1.1 This practice covers a uniform procedure for radioscopic examination of castings. Radioscopic examination of weldments can be found in E1416 . 1.2 This practice applies only to radioscopic examination in which an image is finally presented on a display screen (monitor) for evaluation. Test part acceptance may be based on a static or dynamic image. The examination results may be recorded for later review. This practice does not apply to fully automated systems in which evaluation is performed automatically by a computer. 1.3 Due to the many complex geometries and part configurations inherent with castings, it is necessary to recognize the potential limitations associated with obtaining complete radioscopic coverage. Consideration shall be given to areas where geometry or part configuration does not allow for complete radioscopic coverage. 1.4 The values stated in inch-pound units are to be regarded as the standard. The SI units given in parentheses are for information only. 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 The requirements in this practice are intended to control the quality of the radioscopic images to produce satisfactory and consistent results. This practice is not intended for controlling the acceptability of the casting. The radioscopic method may be used for detecting volumetric discontinuities and density variations that are within the sensitivity range of this practice. The dynamic aspects of radioscopy are useful for maximizing defect response.
