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. 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. 3-point caliper; concrete; cores; lengt
