This document describes the method for assessing the resistance of paint coatings to separation fromsubstrates when a double-X pattern is cut into the coating, penetrating through to the substrate andusing a tape.

Where a measurement of adhesion is required, the method described in CEN/TS 927-9 can be used.

The double X-cut pattern has been especially designed for wood and wood like substrates to minimizethe effects from the incisions and at the same time provide a coating segment enclosed by four cuts.Cross References:CEN/TS 927-9EN ISO 4618ISO 2409ISO 4618EN ISO 2409ISO 29862:2018ISO 4624ASTM D 3359EN ISO 29862:2019 EN ISO 4624
