EN 622-3 Fiberboards - Requirements for Medium Boards

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 622-3 testing. This European standard specifies the requirements for center plates according to EN 316. The values ​​listed in this standard relate to product characteristics but are not characteristic values ​​to be used in design calculations.

EN 622-3 is a European standard that specifies requirements for medium density fiberboards (MDF). MDF is a composite wood product made from wood fibers and resin and is widely used in furniture, construction and interior design applications.

Part 3 of the standard, entitled "Requirements for center boards", provides detailed specifications for MDF products with a density between 600 kg/m³ and 800 kg/m³. These requirements cover various properties of the boards such as mechanical strength, dimensional stability, moisture content and formaldehyde emission levels.

Some of the key requirements outlined in EN 622-3 include:

• Thickness and density: The standard specifies minimum and maximum thickness and density requirements for MDF boards;
• Moisture content: The moisture content of MDF boards should be less than 8%;
• Formaldehyde emission: MDF boards must comply with specific formaldehyde emission limits that vary according to the intended use of the boards;
• Mechanical properties: EN 622-3 specifies minimum requirements for the mechanical properties of MDF boards, including flexural strength, modulus of elasticity and internal bond strength;
• Dimensional stability: The standard contains requirements for the dimensional stability of MDF boards under various conditions such as changes in temperature and humidity.

In general, EN 622-3 aims to ensure that MDF products meet certain minimum quality and safety standards and provides guidance for manufacturers, distributors and end users of these products.
