1.1这些试验方法包括估算钢脱碳深度的程序，与成分、基体微观结构或截面形状无关。可以使用以下基本程序: 1.1.1筛选方法。 1.1.2显微镜方法。 1.1.3显微压痕硬度法。 1.1.4化学分析方法。 1.2如有争议，应采用严格的定量或线性分析方法（见7.3.5和7.3.6）。这些方法可用于任何横截面形状。 化学分析方法通常比显微镜方法显示出更大的脱碳深度，但仅限于某些简单形状和设备可用性。这些技术通常保留用于研究。显微压痕硬度法适用于具有相对均匀微观结构的硬化结构的精确测量。 1.3以国际单位制表示的数值应视为标准值。英寸-磅当量在括号中，可能是近似值。 1.4 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。

1.1 These test methods cover procedures for estimating the depth of decarburization of steels irrespective of the composition, matrix microstructure, or section shape. The following basic procedures may be used: 1.1.1 Screening methods. 1.1.2 Microscopical methods. 1.1.3 Microindentation hardness methods. 1.1.4 Chemical analysis methods. 1.2 In case of a dispute, the rigorous quantitative or lineal analysis method (see 7.3.5 and 7.3.6) shall be the referee method. These methods can be employed with any cross-sectional shape. The chemical analytical methods generally reveal a greater depth of decarburization than the microscopical methods but are limited to certain simple shapes and by availability of equipment. These techniques are generally reserved for research studies. The microindentation hardness method is suitable for accurate measurements of hardened structures with relatively homogeneous microstructures. 1.3 The values stated in SI units are to be regarded as standard. The inch-pound equivalents are in parentheses and may be approximate. 1.4 This standard does not purport to address all of the safety problems, 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.
