BS PD CEN/TS 927-9:2018

BS PD CEN/TS 927-9:2018 specifies a method for assessing the resistance of a coating system on wet wood to separation from the substrate by measuring the force necessary to detach or rupture the coating system by a normal tensile strain applied through an attached stud (dolly). Additional information is gained by noting the type and locus of failure. The force required for detachment will depend on several factors including the adhesion of the coating to the substrate and between intermediate coating layers. The procedure is not regarded as a direct means of measuring adhesion but an indicator of adhesive performance (adherence) under wet conditions.Cross References:EN 23270ISO 3270EN ISO 4624EN 927-3EN 927-6ISO 4624EN 927-2ISO 5725 (all parts)ISO 2409EN ISO 2409
