Paints and varnishes - Coating materials and coating systems for exterior wood - Part 8: Determination of the adhesion on wood after water exposure by a double-X-cut test

active, Most Current
Organization: NEN
Publication Date: 1 March 2020
Status: active
Page Count: 20
ICS Code (Paints and varnishes): 87.040
scope:

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 can be used.

The double X-cut pattern has been especially designed for wood and wood like substrates to minimize the effects from the incisions and at the same time provide a coating segment enclosed by four cuts.
