AT50 mm C1583 Kit

Steps to Perform a Pull-Off Test1. Dolly & Surface PreparationEnsure the steel dolly (disk) is clean and free ofdebris. Remove all surface contaminants and looseor deteriorated concrete from surface.

2. Prepare Test Specimen Using the included 50 mmdiamond-impregnated core bit(barrel), drill a circular cutperpendicular to the surface.Per ASTM C1583 10.1, drill toa depth of at least 10 mm (0.5inches). For tests of repair oroverlay materials, drill to atleast 10 mm (0.5 inches) belowthe concrete-overlay interface.

Measure the diameter of the test specimen in twodirections at right angles to each other and recordthe average diameter, in accordance with ASTMC1583.

Remove any standing water and debris from thesurface and allow to dry.

3. Glue and Dolly ApplicationAttach the steel dolly to the test specimen usingepoxy adhesive. Allow the adhesive to cure per themanufacturer’s instructions taking care to ensure theadhesive does not enter the cut.

ASTM C1583 specifies an ASTM C881 Type IV,Grade 3 epoxy. While the included ResinLab epoxy issuitable for many applications, it does not meet thisspecific requirement.

4. Pull-Off Testa. Ensure the PosiTest AT 50 mm

C1583 stand-off is attached to the actuator.

b. Conduct pull-off test in accordance with PosiTest AT instruction manual.

5. Analysis of Test ResultExamine and report test resultsaccording to ASTM C1583.
