There is no "national standard" for furniture paint inspection.

Buying furniture has encountered quality problems, buyers and sellers are not controversial, the best way is to send furniture for inspection. But Ms. Hu has encountered embarrassment: the new furniture has been in the house for a month, and it still smells bad. Because the furniture is solid wood, the problem is estimated to be in the paint>, but at present there is no national standard and identification method for the detection of furniture paint in China. Ms. Hu’s identification has soaked the soup and the complaint has fallen into a deadlock.
Not long before the smell of solid wood furniture was unpleasant, Ms. Hu added a set of solid wood furniture to her home. I didn’t expect that after the furniture was delivered, it would make the house full of odor and could not live normally. After the complaint was filed with the Consumer Protection Committee, the Consumer Protection Committee immediately contacted the manufacturer.
The person in charge of the factory said that Ms. Hu’s situation has been investigated and there is a certain smell. However, he believes that the furniture is made of solid wood. The taste may be the smell of paint. It should be dissipated after being ventilated for a few days at home. . After another month, Ms. Hu reflected that the taste of the furniture is still very heavy, and everyday life cannot be tolerated.
The lack of furniture paint testing standards, the Consumer Protection Committee said that for furniture complaints, if there is a disagreement between the operator and the consumer on the quality of the furniture, it is generally recommended that the consumer send the furniture for testing. If the test result exceeds the standard, the consumer can Require manufacturers to return. However, because the material of this set of furniture belongs to solid wood, the possibility of smell coming from the wood itself is not great, so consumers and manufacturers think that there is a problem with the paint used in the furniture. Now there is no national standard and identification method for the testing of furniture paint. If the inspection of the furniture material is initiated, the consumer must bear the risk of passing the test results, and bear the economic loss of furniture damage and inspection costs, which makes Ms. Hu’s complaint fall into awkward situations.
Buy furniture considering "fitness rate"
In this regard, the Consumer Protection Committee recommends that relevant administrative functions and testing agencies can conduct relevant research and development as soon as possible, formulate standards and methods for testing furniture paints, and protect consumer interests. At the same time, it is hoped that more manufacturers will comply with standards and use environmentally friendly paints. .
In addition, the use of furniture also has a "fitness rate" for the size of the house, that is, the number of furniture placed in a room with a certain unit volume is limited. If the room is too small, it is not suitable to place too much furniture, otherwise the smell of the furniture itself will not be able to spread, and the accumulation will be excessive, resulting in exceeding the standard. Therefore, when consumers purchase furniture, they should not only consider the style and price of the furniture, but also choose the right furniture according to their own housing area.
