They relate to the moisture content at time of despatch for large and medium sized panels according to E
42、N 12775 and shall be determined in accordance with EN 324-1 and EN 324-2 as appropriate.

BS EN 13353:2008+A1:2011EN 13353:2008+A1:2011 (E)7 If chemically or thermally treated wood is used, the equilibrium moisture content of the panels can differ significantly to those made of natural wood. In that case a deviation from the above men
45、tioned requirements concerning moisture content is possible. If another moisture content is necessary e.g. due to regional climatic condition the appropriate moisture content has to be specified explicitly. 4.3 Bonding quality 4.3.1 General The bonding quality shall be determined in accordance with
46、EN 13354 after the appropriate pre-treatment for use in dry, humid or exterior condition. 4.3.2 Single layer solid wood panel The lower 5-percentile of the shear strength, calculated in accordance with EN 326-1, shall not be less than 2,5 N/mm2.
