Procedure

Overview
A suitable extensibility of a coating film on wood in exterior use is of importance to follow dimensional changes of the wood and to resist some mechanical impacts without formation of cracks in the coating film. The simple method described in this Technical Specification gives evidence on extensibility of a coating film on wood on an ordinal scale and provides first evidence on mechanical behaviour. A similar method exists in EN 13696:2008 for coated wood floorings in interior use but in the present document the description of a carefully selected substrate is added to enable testing of coating materials and coating systems for exterior wood. The method should preferably be used on coatings that have not been exposed to weathering but it may also be applied after ageing of the coating film or under different climatic conditions to gain additional experience. The committee responsible for this DIN SPEC is NA 002-00-15 AA "Bautenbeschichtungen" ("Coatings for masonry") at DIN.
