1.1这些试验方法包括通过X射线照相法测定土壤样品的质量。 1.2这些试验方法使用户能够确定采样和样品内自然变化的影响，这些影响由X射线通过土壤样品的相对穿透程度确定。 1.3只有在通过X射线胶片和X射线样品之间的许多详细比较获得大量经验后，才能充分使用这些试验方法。 1.4以英寸-磅为单位的数值应视为标准值。 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）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 具体预防说明见第6节。

1.1 These test methods cover the determination of the quality of soil samples by X-ray radiography. 1.2 These test methods enable the user to determine the effects of sampling and natural variations within samples as identified by the extent of the relative penetration of X rays through soil samples. 1.3 These test methods can only be used to their fullest extent after considerable experience is obtained through many detailed comparisons between the X-ray film and the sample X-rayed. 1.4 The values stated in inch-pound units are to be regarded as 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 and health practices and determine the applicability of regulatory limitations prior to use. For specific precaution statements, see Section 6.
