NOTE 1 Where a measurement of adhesion is required, see the method described in ISO 4624. NOTE 2 Although the test is primarily intended for use in the laboratory, the test is also suitable for field testing. The method described can be used either as a pass/fail test or, where circumstances are appropriate, as a six-step classification test.A recovery time of 7 days is required at the controlled laboratory conditions prior to testing adhesion per ISO 12944-6 and 14 days prior to testing per ISO 12944-9. In addition to the minimum adhesion requirements described earlier, ISO 12944-9 requires that the coating system retain a minimum of 50% of the baseline (pre-exposure) adhesion.Pull-off adhesion testing is essential for QA, assessing coating durability on various materials. .
