scope:

This standard applies to plants for the production of wood-based panels. Wood-based panels include:

• plywood

- veneer panels

- coreboard

- moulded veneer products

• particleboard

- structural particleboard (including specialist products with additives such as flame retardants) 

- furniture-grade particleboard (including specialist low-density products or products with additives such as polystyrene), see Figure 1

- OSB (particle board composed of oriented long strands), see Figure 2

- moulded wood particle products

• fibreboard

- wood fibre insulation board

- low, medium and high-density fibreboards (LDF, MDF and HDF boards), see Figure 3)

- moulded wood fibre products

• composite board consisting of different types of wood-based panels

The objective of this standard is to

• describe the production technology for woodbased panels,
• identify emission-relevant operations and sources of waste and waste water generation,
• indicate measures for preventing and reducing emissions to air as well as waste and waste water generation,
• propose achievable emission values reflecting the state of the art, and
• provide emission measurement instructions.

Further processes and operations involved in wood machining and processing (e.g. virgin wood processing, refining of wood and wood-based panels by veneering, foiling and coating, combustion of wood and wood-based panels with and without wood preservatives) are described in VDI 3462 Part 1 and Part 3 to Part 5 of the series of standards VDI 3462. Emission measurement instructions are given in VDI 3462 Part 6.
