Nordic standards, focused on furniture raw materials harmful to the environment which may arise chemical composition restrictions. In addition, for the protection of forest ecological resources also made initial requirements. Limit what chemical elements? Limited to what level? On the basis of existing knowledge and research results to international tests. We must protect the environment, but also production feasible.

1) of the raw material requirements

wood furniture raw materials, In addition to the large number of wood and imitation board, there are a small number of plastic, metal, glass, Jiaozhanji and paint. Standards for each raw materials are made by the restrictions.

2) Timber itself no negative impact on the environment. But in the system build factories, sometimes in the sterilization agent treatment to the Blue changed. Sterilization agent then will release harmful gases. France can avoid a dry bacterial erosion. Standards require that products not be used by sterilization agents processed wood materials.

3) imitation board imitation board in a furniture materials was of increasing importance. Most applications also use imitation board veneer or plastic, thin metal films, with noodles. Nordic Construction fibreboard and imitation board environment marked standards, the Nordic eco-labelling scheme has been accepted. Which provides for formaldehyde emissions.

4) metal commonly used for the production of steel and aluminium hinge, slipway and other components. Its surface or switched two ways to deal with electroplating. Electroplating could lead to contain chromium, nickel, cadmium and (or) zinc compounds, which discharged into water to form a larger environmental hazards. Toxic chlorinated organic solvents may be used for dry and crafts. At present, the non-metallic acrylic powder processes or good paint solvents increasing use their small to environmental hazards. Metal processing and performance standards for handling denial of halogenation organic solvents. In addition such as screws, hinge, ornaments and small pieces of parts, the metal should not use cadmium, nickel, chromium and their compounds in electroplating. Should not contain metal paint to lead, cadmium, chromium, mercury and their compounds based paints and additives; Which can not exceed 5% of organic solvents (weight).

5) may be used for transparent glass windows, desktop, shelving. Glass itself does not harm the environment. But lead glass installed in the standard is prohibited. Lead glass is glass with embedded metal framework manufacture of components manufactured materials. Lead glass production and production wastes are harmful to the environment. Lead can accumulate in the soil and aquatic toxic substances. It can enter plants accumulate in biological chain. Lead to be classified as environmentally harmful heavy metals.

6) Jiaozhanji and paint (including for surface treatment chemicals) imitation board production, as well as its front face, Fengbian, and some wood components interface must use Jiaonianji. Most of the amino resins category Jiaozhanji imitation board, which thiourea aldehyde resin plastic applications particularly wide. Jiaozhanji commonly used furniture production, with the exception of amino resins plastic, the plastic is gathered acetate ethylene esters tanks (commonly known as white latex) and ethylene -- acetate ethylene You resin plastic (Rerongjiao one).

in Nordic, 80% of the volume of furniture paint are sour solidification paint. Solidification paint ingredients is sour solid thiourea -- formaldehyde and (or) Sanjuqingan formaldehyde or alkyd resins. There are other paint Juanzhi, nitro - cellulose, ultraviolet solidification of polyester and acrylic acid, good paint, vegetable oil. Inter small amount of polymer, thermosetting acrylic acid and toxic solvents, vegetable oil. Other paint contain substantial organic solvents : the ability of the content to paint 10% of the content is as high as other 50%--80%. 'd paint the most solid hours to Jubingxi basis. Yan main use flax oil vegetable oil, or mixed with turpentine. Good paint and vegetable oil in the increasingly popular in recent years as a substitute for other paint. To obtain a certain performance Jiaonianji and chalk materials may also contain various additives. Seqi also contain pigments. Used in the production of furniture containing phenolphthalein 0-5% Jiaonianji general. Other chemicals used for surface treatment may be sodium alkali, potash, acid and tannins Zhonggesuanjia.

standards require that in any of the Nordic countries, for the timber Jiaozhanji and paint, not by allergies, toxic, carcinogenic, or to change the classification to harm reproduction.

Jiaozhanji and paint for the greatest attention is focused on amino resins from the category Jiaozhanji formaldehyde emissions. Formaldehyde problem is hazardous to health. It is a stimulating agent, the gas stimulate the eyes, and respiratory membranes, solution may cause skin, eye; And was classified as carcinogens. It also flammable. Gas concentrations in persons sensitive to (0.01--0.05) X 10-6, which was stimulated. However, the lower formaldehyde content Jiaohejiangduo general also been reduced. Industry has been working hard to reduce Jiaozhanji and paint the floating formaldehyde emissions. Now thiourea aldehyde resins for the production of plastic furniture, floating formaldehyde content may sometimes as low as 0.25% (weight), containing about 1% of the standard type. The standards allow for the largest floating formaldehyde content in the paint 0.5%; formaldehyde emissions from more than 0.1 x 10-6. Formaldehyde emissions with the use of simulated environmental conditions of climate boxes law tests. Can test the pieces of furniture that can contain formaldehyde testing of all materials, components for manufacturers selected.

paint, organic solvents primarily alcohol and esters, harmful to health. It was the entire space, so that fresh air lost. Standards require that the use of chemicals organic solvents may not exceed 5%.

standards for the chemical composition of other hazardous to the environment also made restrictions. In Jiaonianji and paint, where the Nordic contain any national standards and regulations classified as environmentally harmful chemical substance, the amount should not exceed 1% each (weight), but they should not exceed 2% of the total. Chemicals should not contain provisions tin organic compounds, halogenation organisms (for Jiaolianji, fire agents, solvents) or aromatic solvents. Plastic materials should not contain the above listed phenolphthalein and heavy metals and their compounds.
