Furniture formaldehyde testing will have new standards

The three National Standards Examination and Approval Conference, "Limits on Hazardous Substances in Wood Furniture", "Climatology Class for Detection of Volatile Organic Compounds in Furniture" and "Determination of Volatile Organic Compounds in Furniture" sponsored by the National Furniture Standardization Technical Committee, were held in Shanghai. , It makes clear that the limits of harmful substances in furniture, furniture health will have updated standards, but also make home security more assured.

Zhu Changling, chairman of the China Furniture Association, said that the new national standard is more scientific, more rigorous, and the testing content is more varied. The protection for consumers is also more comprehensive.

The current standard is too loose. Last year, the Guangzhou Bureau of Quality Supervision released a test report on furniture. The report shows that the quality of furniture on the market is still not optimistic. In particular, the problem of excessive formaldehyde emission from plate furniture is more serious and has been detected as unqualified. In products, formaldehyde exceeded 30%. According to the analysis, the main reason for excessive formaldehyde is that the manufacturer uses inferior wood-based panels and inferior adhesives to reduce costs.

The National Furniture Product Quality Supervision and Inspection Center stated that China’s furniture products have rarely used solid wood, and most of the panel furniture uses fiberboard or particle board bonding. In this way, adhesives should be used for veneers and edge bands. The adhesive is the source of formaldehyde.

Do not look at the market there are so many furniture formaldehyde exceeded, in fact, compared with the relevant standards in Europe and the United States, China's formaldehyde emission testing standards for furniture is relatively loose: China's furniture formaldehyde content testing still follow the standard introduced in 2001, in this In the standard, the formaldehyde release limit is not more than 1.5 mg/L.

Detection methods cause difficulties in the detection of rights, China and the United States are also very different, China's furniture product testing follows the "dryer method", the United States is using the "environmental testing warehouse law", the difference between the two is that the American method Without destroying the whole furniture product, the furniture is placed in an environmental warehouse to collect gas. The detection process does not destroy the structure of the furniture. The biggest advantage is that the detection process simulates the environment in which the furniture is used, which is in good agreement with the actual situation. The instrument method is to cut the furniture into small pieces for testing. It is a destructive test that not only destroys the furniture, but also differs from the reality of furniture use.

Different detection methods make consumers inconvenience in rights protection. According to media reports, the complaint that furniture was not environmentally friendly in May last year reflected the frustration of consumers under the old standard. When Mr. Guo tested the empty room, the indoor air quality was up to standard, and it was tested after being put into the furniture. The indoor air quality was not up to the standard. He reflected the situation to the furniture dealer. The other party stated that all the furniture had reached the standard. If Mr. Guo thinks that the standard is not met, he can send the furniture to the relevant department and carry out destructive testing according to the current national standard. If it is not up to the standard, the dealer is willing to take corresponding responsibility. Instead, Mr. Guo is responsible.

This said that Mr. Guo is very embarrassed. According to experts' explanations, the home he purchased may have reached the national standard because of sampling and testing in proportion. However, the use of wood is too large. The superposition of harmful substances leads to the failure of indoor air quality and therefore damages. The result of sex test is not necessarily beneficial to him. Mr. Guo has to bear the risk that the furniture will be destroyed but no compensation will be paid.

The new standard will have three breakthroughs and the implementation of the new national standard will better protect consumers' home security. According to Zhu Changling, the revised new furniture testing standard will reflect its advantages in three aspects.

Good overall detection, results are more reliable The revised new test standard requires the use of climate chambers as a whole. The data obtained from the “climate box test” in a room that maintains constant temperature and humidity can more accurately reflect the poisonous and harmful substances of the inspectors. The actual release of the overall situation, the method will be more scientific and more rigorous help consumers control the environmental protection coefficient of furniture.

Good 2 non-destructive testing, detection of low risk of furniture destructive testing so many consumers want to defend their rights back out, Mr. Guo failed to take this crucial step, but also afraid of "losing his wife and soldiers."

The new climate chamber detection method is much more advanced than the current method, making up for the loopholes in the current detection methods. The entire piece of furniture is placed in a specific environment for testing. The furniture itself does not have any degree of damage. This is for consumers. Good things, if the test results are not satisfactory, you can find a business to claim compensation. If the test results are up to the standard, then you can count the cost of the test, and you can also buy a peace of mind.

Good 3 environmental protection furniture, renamed as a matter of fact Today's furniture is no longer a single piece of wood, a lot of furniture using glass, metal or even sponge filler and other materials, the current detection method because only for the detection of the wooden part, can not objectively reflect The overall environmental protection status of the furniture, and climate chamber testing can include all parts of the furniture into the scope of testing, testing the overall environmental protection status, and can also determine the release of harmful substances such as furniture VOCs while testing formaldehyde, and the test results are more comprehensive and reliable. .
