Technical Specification





Language in which you want to receive the document.


This document describes the method for assessing the resistance of paint coatings to separation from substrates when a double-X pattern is cut into the coating, penetrating through to the substrate and using a tape.
Where a measurement of adhesion is required, the method described in CEN/TS 927-9 may be used.
The double X-cut pattern has been especially designed for wood and wood like substrates to minimise the effects from the incisions and at the same time provide a coating segment enclosed by four cuts.
