Over deze norm
1.1 This test method covers the determination of delaminations in portland-cement concrete bridge decks using infrared thermography. This test method is intended for use on exposed and overlaid concrete bridge decks.
1.2 A Precision and Bias statement has not been developed at this time. Therefore, this standard should not be used for acceptance or rejection of a material for purchasing purposes.
Note 1—This test method can be used on asphalt or concrete overlays as thick as 4 in. (100 mm).
1.3 This test method uses an imaging infrared scanner and video recorder, mounted on a vehicle, to detect delaminations and debonded areas on bridge decks and to record the information.
1.5 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.
