Phạm vi áp dụng / Scope of standard

This test method covers obtaining, preparing, and testing (1)
cores drilled from concrete for length or compressive or splitting
tensile strength determinations. This test method is not applicable
to cores from shotcrete.

Note 1-ASTM Test Method C1604/C1604M is
applicable for obtaining, preparing, and testing cores from
shotcrete.

Note 2-Appendix X1 provides recommendations for
obtaining and testing sawed beams for flexural performance.

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 may
not be exact equivalents; therefore, each system shall be used
independently of the other. Combining values from the two systems
may result in nonconformance with the standard.

The text of this standard references notes and footnotes that
provide explanatory material. These notes and footnotes (excluding
those in tables and figures) shall not be considered as
requirements of the standard.

This standard does not purport to address safety concerns
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.
