Recently, with the frequent occurrence of environmental protection issues in the field of furniture and building materials, decoration pollution has once again become the focus of public opinion. When the integrity of the business is questionable, many consumers have begun to rely on "environmental testing" and hope to protect their rights through legal means. But what can the "indoor environment test" measure? When is it suitable for testing? Is the inspection cost high? Consumers have a lot of questions about this.

what you do not know
We all know that the qualification of the furniture sheet does not mean that the furniture manufactured after superposition, bonding, painting and other processes are also environmentally friendly. Since China does not have the testing standards for the overall furniture, if the furniture bought home smells great, how should consumers protect their rights?
Expert advice
1. Odor pollution and chemical pollution are not necessarily equal. Good indoor environmental quality is based on the premise of “non-toxic, harmless, no abnormal smellâ€. If the furniture bought back feels a big smell, although it is not necessarily formaldehyde, It is not necessarily a volatile organic substance, but it can definitely have a negative effect on the quality of the indoor environment. There is no need to do further testing. It should be directly returned to the factory for return, and the formal brand will fulfill the corresponding responsibility.
2. If you encounter a "real" business, you can use environmental testing to help solve the problem. The premise is that under the same space conditions and normal use of furniture, the indoor environment values ​​of a certain household with and without two cases are respectively measured, and the comparative values ​​are used for speaking. When using this method, it is preferable to have a business person at the scene.
Can indoor environmental testing be used to detect furniture?
The quality of a piece of furniture depends on the materials, technology and post-processing. Refer to the "Limited Standards for Hazardous Substances in Interior Decoration Materials". At present, the country only has provisions for the safety standards of ten kinds of building materials such as wood-based panels, paints and adhesives. There is no clear indication of the requirements for furniture, so even if it is tested, it is difficult to use as a basis for product return.
In addition, the same piece of furniture is placed in a space of 10 square meters and a space of 50 square meters, the measured pollution value is obviously different, which is also related to the orientation of the room and ventilation, so the test does not necessarily reflect the real situation. . It has been proposed to test the release of pollutants in furniture in a standard environmental warehouse to develop a test standard, but because each piece of furniture is different in size, material and process, it is very difficult to quantify the standard.
Under what circumstances is it suitable for indoor environmental testing?
The indoor environment test is mainly used in the decoration acceptance stage. For the owner of the decoration, even if the furniture purchased is guaranteed to be environmentally friendly and non-toxic, all the furniture pollutants will accumulate together, and it will inevitably exceed the normal value. In this case, You can check the quality of the environment after renovation, decide when to stay, and whether you need to take improvement measures.
For owners who have purchased a hardcover room, it is also necessary to conduct a second test. Although the developer will provide the indoor environmental test report of the project when the house is delivered, the developer first provides the sampling report, which cannot explain the specific situation of each house. Secondly, the developer's test is for the project acceptance, and may be in the blank. In the room phase, not the hardcover test, the results will be different; in addition, according to the "Civil Building Engineering Pollution Control Code" project acceptance criteria, it is detected after one hour of indoor closure, while the national indoor air standard requires indoor After 12 hours of sealing, the test is carried out, so that the second detection can find the problem in time.
What are the qualifications and fees for indoor environmental testing?
At present, there are dozens of indoor environmental testing organizations in Beijing. These institutions can be found on the website of the State Quality Supervision Bureau or the Beijing Quality Supervision Bureau. Only the testing reports issued by the testing institutions that have passed the national laboratory measurement certification have According to the legal basis, the simplest method of identification is to have the CMA (China Metrology Certification) mark in the upper left corner of the test report.
In general, indoor environmental testing mainly tests five major items: formaldehyde, benzene, volatile organic compounds, ammonia, and radioactive elements. The surveying staff will determine the test point according to the room area. The more the test point, the higher the cost. Although there is no uniform charging standard for the country, the industry generally charges about 300 yuan for a project. The cost of testing a 100 square meter house is about 1000 yuan up and down.
How to reduce decoration pollution
Reduce carpentry
Try not to let the workers do the woodworking at the decoration site. Generally, the woodworking will use the large core board or the MDF as the material. The quality and environmental protection are difficult to guarantee, and even affect the quality of the second decoration. If you want to customize the furniture, it is best to ask the furniture manufacturer to measure on site, and the furniture is produced at the factory.
Pursuit of simplicity
The more materials used for decoration, the more the pollutants are added, the more likely it is to cause decoration pollution, so when pursuing decoration, try to pursue simplicity.
Look for plates
Although wood-based furniture has high formaldehyde content, most of the plate furniture on the market is of high quality because the country has strict inspection standards for plates. But nowadays, many solid wood composite furniture, with the signboard of solid wood, uses the plate as the core material, and does not produce the standard of the plate. Consumers should be careful when purchasing such furniture.
Reasonable match
The decoration materials should be reasonably matched. For the floor materials with the most use area, the laminate flooring will release formaldehyde. The surface of the solid wood flooring contains volatile organic compounds. The tiles have certain radioactivity, so designers should use solid wood, laminate flooring and ceramic tiles as much as possible. For example, the living room chooses durable laminate flooring, the bedroom chooses comfortable solid wood flooring, and the kitchen and bathroom choose clean tiles, which meets the characteristics of the material itself and is environmentally friendly.
Auxiliary equipment
The air purifier can adsorb, decompose or convert various air pollutants, including dust, pollen, odor, formaldehyde and other decoration pollution; and can also place some green plants with purification effect, aloe vera, spider plant, tigertail orchid, turtle The back bamboos are natural scavengers and have a strong ability to absorb formaldehyde.
Reasonable ventilation
When the room temperature is below 15 °C, the amount of pollutants released is very small, so you can choose to close the door and window to open the air conditioner to a higher temperature. When the pollutants are released to saturation, open the window to ventilate and discharge the pollutants.
