Complete knowledge of wooden flooring product testing
The main types of wooden flooring include: bamboo flooring, solid wood flooring, solid wood composite flooring, reinforced wood flooring, etc
Bamboo flooring: It is a new type of building decoration material, which is made from natural high-quality bamboo as raw material. After more than 20 processes, the bamboo pulp is removed, and it is pressed under high temperature and pressure. It is then coated with multiple layers of paint and finally dried with infrared radiation.
Bamboo flooring has the characteristics of fresh and natural color, smoothness, high strength, good toughness, and wear resistance, and has been widely used in indoor decoration.
Testing items: specifications, dimensions and deviations, appearance quality requirements, moisture content, static bending strength, immersion peel test, surface paint film wear resistance, surface paint film pollution resistance, surface paint film adhesion, surface impact resistance, formaldehyde release, and other indicators.

CECS191:2005 Technical Specification for Wooden Floor Paving Engineering.
Solid wood flooring: It is a floor decoration material formed by drying and processing natural wood. Also known as log flooring, it is a floor made directly from solid wood. It has the natural texture of wood growth, is a poor conductor of heat, can play a role in keeping warm in winter and cool in summer, has comfortable foot feel, and is safe to use. It is an ideal material for floor decoration in bedrooms, living rooms, study rooms, and other areas.
Testing items: specification size and deviation, shape and position deviation, appearance quality, moisture content, surface paint film wear resistance, surface paint film adhesion, paint film hardness, etc.
Testing national standard: GBT 15036.1-2009 Technical Requirements for Solid Wood Flooring. Solid wood flooring products suitable for this testing standard mainly include tenon joint solid wood flooring, flat joint solid wood flooring, antique solid wood flooring, unpainted solid wood flooring, painted solid wood flooring, and oil decorated solid wood flooring.
Solid wood composite flooring: It is a type of flooring derived from the solid wood flooring family, and is actually a new type of solid wood flooring. It is made by interlacing and laminating boards of different tree species, overcoming the disadvantage of unidirectional isotropy of solid wood flooring. It has a low dry shrinkage and moisture expansion rate, good dimensional stability, and retains the natural wood grain and comfortable foot feel of solid wood flooring. Solid wood composite flooring combines the stability of reinforced flooring with the aesthetics of solid wood flooring, and has environmental advantages. It has also become a popular flooring type in European and American countries due to its natural woodiness, easy installation and maintenance, anti-corrosion and moisture-proof, antibacterial, and suitability for geothermal energy, and is favored by many families in China.
Testing items: materials, specifications, dimensions and deviations, appearance quality, immersion peeling, static bending strength, elastic modulus, moisture content, surface paint film adhesion, paint film hardness, surface wear resistance, surface pollution resistance, formaldehyde release, and other indicators.
National standards:
GB/T 2828-1987 Batch by batch inspection, counting and sampling procedures and tables (applicable to continuous batch inspection) GB/T 4893.4-1985 Furniture surface paint film adhesion cross cutting method GB/T 9846.1-9846.12-1988 Plywood GB/T 13009-1991 Tropical broad-leaved wood ordinary plywood GB/T 15102-1994 Impregnated adhesive film paper veneer artificial board GB/T 15104-1994 Decorative veneer artificial board
GB/T 17657-1999 Test methods for physical and chemical properties of artificial boards and decorative artificial boards
Laminated wood flooring: generally composed of four layers of composite materials, namely wear-resistant layer, decorative layer, high-density substrate layer, and balance (moisture-proof) layer. Laminated flooring, also known as impregnated paper laminated wood flooring or reinforced wood flooring, is qualified by using one or more layers of specialized impregnated thermosetting amino resin.
Testing items: specifications, dimensions and deviations, appearance quality, static bending strength, moisture content, internal bonding strength, density, water absorption thickness expansion rate, surface bonding strength, surface resistance to cold and hot cycles, surface resistance to scratches, dimensional stability, surface wear resistance, surface resistance to cigarette burning, surface resistance to dry heat, surface resistance to pollution and corrosion, surface resistance to cracking, impact resistance, formaldehyde release, and color fastness to light.
