With the enhancement of people's awareness of environmental protection, the requirements for the Environmental Protection standards achieved by home furniture are also getting higher and higher. However, around the market, some businesses said that their products are the national standard E1 level, some said to reach the E0 level, in addition to F4 stars, CARB certification, etc., dazzling. What do these plate standards mean after all? Which is the most environmentally friendly? Recently, the reporter visited some stores and experts to answer readers 'questions.
National Standard only E1, E2
"We are at the domestic E1 level and the European E0 level. "A few days ago, in a store in Chaoyang District, the sales staff of a brand of wooden doors told reporters that wooden doors were divided into pure solid wood, solid wood composite, and sandwich doors. Since wooden furniture such as wooden doors, flooring and cabinets, tables and chairs are all man-made panels and their products, they are all suitable for GB18580-2001 "Limited formaldehyde release limits in indoor decoration materials man-made panels and their products."
The country's standard divides man-made panels and their products into three categories: first, medium-density fibreboard, high-density fibreboard, particle board, directional particle board, etc.; Second, plywood, decorative veneer plywood, fine wood board, etc.; Third, decorative panel(including impregnated paper laminate wood floor, solid wood composite floor, bamboo floor, impregnated film paper surface artificial board, etc.).
The first two types of formaldehyde releases are divided into E1 and E2 levels, E1 levels can be used directly indoors, and E2 levels must be decorated before being allowed to be used indoors. According to the different test methods, the formaldehyde limit values and units of these two types are also different. Among them, the first type of E1 limit value ≤ 9mg/100g, E2 ≤ 30mg/100g. The second type of E1 ≤ 1.5 mg/L, E2 ≤ 5 mg/L. The third category is only E1, IE ≤ 1.5 mg/L.
"Our domestic standards lag behind Europe. In Europe, there is E0, and formaldehyde emissions ≤ 0.5 mg/L. " said the salesman.
The reporter's investigation found that although the national standard does not have an E0 level, many businesses have played the E0 flag. From building materials to furniture, and there are no shortage of brand names. Because the lower the formaldehyde content, the higher the raw materials, production technology and processing technology requirements of the enterprise, often only the best in the industry can do it.
E0 is an enterprise's own non-statutory standard
However, the reporter inquired about the relevant information and found that even in Europe, the official standard does not have the so-called E0 level. Songguangsheng, director of the China Interior Decoration Association and the Indoor Environmental Monitoring Working Committee, said that the so-called E0 level is often a kind of hype. It is a corporate standard formulated by some manufacturers to improve product quality. Most of them set the formaldehyde release ≤ 0.5 mg/L as E0, but they can not set standards in Europe. The E0 signboard that some local manufacturers hang out is also their own level, and there is no formal institutional certification.
Not only that, there are also many cases in which businesses have been awarded compensation because of the promotion of the E0 standard, after which environmental protection failed to meet the standards. A cabinet merchant who claimed to use the "E0 cabinet substrate" was sentenced to 15,000 yuan by the court because he could not produce a legal and effective E0 plate test report.
National standard formaldehyde classification is not scientific
However, the reason why businesses are competing to promote the E0 level is inextricably linked with the national standard lagging behind consumers 'environmental protection needs. Wang Zheng, deputy director of the Institute of Timber Industry of the Chinese Academy of Forestry, said recently that although GB18580-2001 stipulated the concentration of man-made panels, it did not specify the total amount of indoor control, that is, only the unit release control, but did not use the total amount of man-made panels. Control, when the amount of man-made panels reached a certain degree, The amount of formaldehyde released accumulates will exceed the standard. "Objectively speaking, the current national standard has become an umbrella for formaldehyde's 'legal excess'. This has also led many consumers to lose the lawsuit against the factory. The enterprise is to benefit, as long as I reach the national standard, you can not say that I exceed the standard, as for the total amount of formaldehyde brought about by the enterprise is not illegal. On the other hand, the fault lies not with the enterprise, but with the national standard. "
Wang said that in Japanese standards, F1, F2 and F3 levels correspond to China's E2, E1 and E0 levels. The F1 product is not allowed to be used indoors. Although the F2 and F3 levels are allowed to be used indoors, the total amount of use will be strictly controlled; If the F4 level(≤ 0.3 mg/L) is reached, it is not limited by the total amount of use because this product is very safe.
Relevant standards will be upgraded
With scandals such as anxin's poisoned flooring exposed last year, the standard upgrade of artificial panels and their formaldehyde products was put on the agenda. In May this year, the National Standardization Administration disclosed that it intends to revise the above-mentioned national standards. In the revised version, the E2 standard will be deleted. Once the draft is adopted, the formaldehyde limit release value of the future sheet building materials product will be ≤ 1.5 mg / L.
In the same month, Taoyiming, Secretary General of the China Timber and Wood Products Circulation Association, also stated at the "2013 China Artisanal Plate Industry Development Summit Forum" that the Ministry of Commerce approved the establishment of the project and the implementation of the China Timber and Wood Products Circulation Association. The "Green Plate Evaluation Standard" will soon be issued. The standard mainly regulates the definition of green man-made panels, production raw materials and process requirements, product quality and safety performance requirements, and inspection methods. It will be linked to the green standards of foreign panels such as CARB certification in the United States and JAS certification in Japan. The standard will enable the industry to gradually become a green industry based on green standards, providing consumers with real green products.
Strict American CARB and Japanese JAS certification
It is reported that CARB is the abbreviation of "California Air Resources Committee". The air transmission control measures issued by CARB to reduce formaldehyde emissions from composite wood products are the most stringent international standards for formaldehyde releases from composite wood products. one. The standard not only stipulates the formaldehyde limit, but also requires manufacturers to strictly supervise the factory's production process in accordance with the quality management system required by the regulations, and even has corresponding requirements for importers, traders, and retailers. Composite wood products and finished products containing composite wood products that are not certified by CARB will not be able to enter California.
The JAS Act is a "Japan Agricultural Standard" formulated by the Japanese Ministry of Agriculture, Forestry and Fisheries. All organic products and raw materials exported to Japan must comply with this standard. Only JAS-certified products and ingredients can be sold on the Japanese market. Some domestic building materials or furniture manufacturers will promote their own environmental protection to reach F4 stars. This is the highest level of environmental protection for wooden building materials in Japan's current law and is also considered to be the most healthy standard in the world.
