Particleboards – Part 6: Requirements for heavy-duty load-bearing boards for use in dry conditions – Specification
Description
This Botswana Standard specifies the requirements for boards for heavy duty load-bearing boards for use in dry conditions. Particleboards complying with this standard may also be referred to as P6-boards. This standard does not give requirements for oriental strand boards (OSB) and it does not apply to extruded particleboards.
NOTE 1 These boards have enhanced properties with those specified in BOS 308-4. They may also be used in design and construction of load-bearing or stiffening building elements. e.g. walls, flooring and I-beams.
NOTE 2 Dry conditions are characterized by moisture contents in the material corresponding to a temperature of 20 oC and the relative humidity of the surrounding air only exceeding 65 % for a few weeks per year. Boards of this type are only suitable for use in biological hazard class of EN 335-3.
