1.1本试验方法包括通过测量从混凝土结构中钻取的芯的长度来确定混凝土路面、板或结构元件的厚度。 1.2以国际单位制或英寸-磅单位表示的数值应单独视为标准值。在文本中，英寸-磅单位显示在括号中。每个系统中规定的值不是精确的等价物；因此，每个系统应相互独立使用。 1.3 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。 ====意义和用途====== 本试验方法用于确定混凝土结构是否符合设计规范。它在确定路面和其他板结构的厚度时尤为重要。

1.1 This test method covers the determination of the thickness of a concrete pavement, slab, or structural element by measuring the length of a core drilled from a concrete structure. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the inch-pound units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. 1.3 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. ====== Significance And Use ====== This test method is used to determine the compliance of concrete construction with design specifications. It is especially important in determining the thickness of pavements and other slab construction.
