European Free Trade Association.
Compared to CEN/TS 12872:2007 the following changes have been made:
a) deliverability changed from CEN/TS to CEN/TR;
b) references to requirements according to EN 12871 deleted after transformation of EN 12871 into a test
method standard;
c) in 10.2, Table 2, values of dimensional changes depending on moisture content for multilayer solid wood
panels added
d) presentation of wall and roof constructions in Clauses 14 and 15 indicated as basic examples;
e) recommended expansion gaps for walls and roofs in Clauses 14 and 15 reduced.
