stopping. Calculate the time the stress should be increased over and practice before testing. The table
shows how many seconds each turn should take - see Table 1. Some Standards allow a slower rate (more
seconds) up to a maximum time.
Table 1:
WARNING: There will be a loud bang and the Adhesion Tester may jump up a few centimetres
as the dolly and coating detach and the energy in the tester is released. For personal safety it
is recommended that the operator does not lean over the Adhesion Tester during use.
4. Immediately after the test is complete and the pull-off force has been recorded, slacken the handwheel
or nut to remove all the force from the unit.
2.4 ASSESSING THE RESULTS
To record the result, first inspect the face of the dolly. In most cases the coating will fully adhere to the dolly
and the test can be claimed as 100% valid. In some cases, the coating will cover only part of the area of the
dolly and a partial adhesion failure should be recorded.
