Wood-based boards, non-load-bearing and load-bearingSP tests boards for non-load-bearing purposes and load-bearing boards for constructive use in walls, floors and roofs as well as performs production control of the area. SP also has its own method for testing of stepping through security, which has been developed to meet the regulations of the Swedish Work Environment Authority.
The certification can be done by P-marking or CE marking according to EN 13986. P-marking of a product aims to clearly show the product buyers and users that it meets the Swedish requirements. Wood-based boards for construction purposes, regardless of being load-bearing or not, must today be CE marked for the harmonised standard EN 13986. Testing of wood-based boards for floors and roofs takes place according to EN 1195/EN 12871 (static and dynamic point load). Testing of walls takes place according to EN 12871/EN 596 (soft impact)/EN 594 (strength and stiffness, so called racking test).
Boards can also be material tested according to a number of standards, e.g.:
- EN 310 Bending strength and modulus of elasticity (Wood-based panels - Determination of modulus of elasticity in bending and of bending strength)
- EN 317 Determination of swelling in thickness (Particleboards and fibreboards - Determination of swelling in thickness after immersion in water)
- EN 319 Tensile strength perpendicular to the plane (Particleboards and fibreboards - Determination of tensile strength perpendicular to the plane of the board)
- EN 321 Resistance (Wood-based panels - Determination of moisture resistance under cyclic test conditions)
- EN 314-1 and EN 314-2 Plywood (Plywood - Bonding quality - Part 1: Test methods) (Plywood - Bonding quality - Part 2: Requirements)
- EN 789 Mechanical properties (e.g. bending, pressing, pulling and shearing) (Timber structures - Test methods - Determination of mechanical properties of wood based panels)
Boards tested can for example be ordinary particle boards or plywood boards. Testing according to EN 12871 takes place with more or less ready roof, wall or floor structures, e.g. particle boards, roof plywood, heating floors or raised floors.
SP can also determine the formaldehyde content according to the perforator method (EN 120) and formaldehyde in the chamber for example, CARB, P-marking or CE marking.
