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

Warning— Concrete specimens tested with unbonded caps rupture more violently than comparable specimens tested with bonded caps. 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.
