1.1This test method is suitable for both field and laboratory use to determine one or more of the following:

1.1.1The near-surface tensile strength of the substrate as an indicator of the adequacy of surface preparation before application of a repair or overlay material.

1.1.2The bond strength of a repair or an overlay material to the substrate.

1.1.3The tensile strength of a repair or overlay material, or an adhesive used in repairs, after the material has been applied to a surface.

1.2The values stated in either SI units or inch-pound units are to be regarded separately as standard. 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 non-conformance with the standard.

1.3This 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.
