The minimum release limit of formaldehyde is three times that of international
Zhang Yucheng, a visiting professor at the Department of Wood Science at Tianjin University of Science and Technology and former deputy secretary-general of the Tianjin Furniture Association, told the â€œFirst Financial Dailyâ€ that there are currently two major problems in the furniture industry. The instructions for use are ineffective and the standards are too low.
Just as the milk national standard is too low in the past, the furniture industry also has too low standards. Zhang Yucheng admits that many standards in the furniture industry have been set too low, "some standards are even three times lower than international standards."
For example, in Zhang Yucheng, the standard for formaldehyde in wooden furniture materials is three times lower than the international standard.
The national standard GB18580-2001 "decorative limits of formaldehyde in wood-based panels and their products for interior decoration materials" clearly stipulates that the limit of formaldehyde emission in domestic furniture raw materials and decorative materials is E1, as long as the emission of E1 formaldehyde is not exceeded. 1.5 mg / liter can be used indoors. The internationally accepted standard is the E0 standard, which requires that the amount of formaldehyde released does not exceed 0.5 mg / liter. In Japan, the F4 star standard has already been adopted, that is, the average formaldehyde emission limit of building materials cannot exceed 0.3 mg/L.
"Because Chinese furniture companies are all technically difficult to meet international standards, the state and industry associations have considered the development of the industry and temporarily lowered the industry standards, but at the expense of the health of the people." Zhang Yucheng lamented.
Formaldehyde was declared a first-class carcinogen by the World Health Organization in 2004. According to the survey conducted by the China Center for Disease Control and Prevention in October 2005, 60% of the formaldehyde in the process of renovation of households in China exceeded the standard. In 2009, Shanghai Environmental Protection Industry Association announced a set of data. The indoor air test results of Shanghai households from 2008 to 2009 showed that 91.2% of households had excessive formaldehyde emission in summer, and mainly used plates with poor environmental performance. cause.
According to Zhang Yucheng, the results of environmental testing in some cities in the country in the first half of this year showed that more than 90% of the office buildings in Tianjin, Shanghai and other cities did not meet the indoor environment. Standard form
The "Guidelines for the Use of Consumer Goods, Part VI: Furniture" promulgated by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China clearly stipulates that the furniture sold must have instructions for use (labels, signs, instructions for use), and the instructions for use must clearly state the environmental conditions applicable to the furniture. According to the characteristics and needs of the furniture, indicate the structure, materials used, performance, type, specifications, environmental indicators must be clearly stated, if the furniture purchased by the consumer has quality problems, or does not conform to the manufacturer's promise, the instruction manual Will have legal effect.
However, the implementation of this standard in China is not in place. Zhang Yucheng even confessed: "There is no one in the market that is in place."
In the labeling of furniture goods, the furniture dealers have not complied with the industrial product labeling requirements of the State Administration of Quality Supervision. According to the regulations, all industrial products must be clearly written, including what materials are used, how to do them, environmental standards, specifications, dimensions, There are no production licenses, etc. According to national regulations, if there is no strict manual and clear labeling, the furniture is deemed to be a non-conforming product and is prohibited from being sold in the market.
On February 6, the reporter visited some furniture markets in Shanghai and found that few furniture dealers can provide instructions for the use of related products.
At the Red Star Macalline Hutai Road Store, the reporter visited more than 20 merchants, and almost none of them were able to provide compliance instructions. A merchant told reporters that because the Red Star Macalline will occasionally check the commodity certificates and instructions of each merchant, many merchants will still have such a manual, but as far as the manual and the certificate are in compliance with the regulations, it seems that there is no management. Over.
According to a survey conducted by a university in Tianjin, the current furniture market mainly has the following problems: the product manual, the instruction manual or the product manual of the furniture are not provided, and the contents of the instruction manual do not meet the requirements stipulated by the state; the physical raw materials are inconsistent with the description of the manual; The amount of substance released did not meet national standards.
