NOTE 2 Service class 2 is characterised by a moisture content of the material corresponding to a temperature of 20 °C and a relative humidity of the surrounding air exceeding 85 % for only a few weeks per year. 3.1.3 solid wood panel for use in exterior conditions panel intended for use in unprotected external applications as defined in service class 3 of EN 1995-1-1 and use class 3 of EN 335-2 NOTE 1 It is also capable of withstanding exposure to weathering conditions and liquid water, or water vapour in a damp but ventilated location where it can frequently attain a moisture content above 20 %. NOTE 2 Service class 3 is characterised by a moisture content of the material higher than service class 2. 3.2 Classes for solid wood panels indicating their intended use 3.2.1 Technical classes for non-structural use SWP/1 NS: Solid wood panel for non-structural use in dry conditions according to 3.1.1 SIST EN 13353:2009

Nevertheless products should not be limited by the requirements according to the technical classes. Therefore classes based on declared values may be used for such prod-ucts. 4 Requirements 4.1 Dimensional tolerances The tolerances for the nominal length, width and thickness, thickness within the panel, edge straightness and square-ness are given in Table 1. They relate to the moisture content at time of despatch for large and medium sized panels according to EN 127
