With the increasing pursuit of quality of life, environmental protection has become an important reference factor for consumers when purchasing furniture. At present, the concept of "zero formaldehyde" is on the market. However, experts advise consumers not to superstition the concept. Even large-brand and expensive-priced plate products have certain levels of formaldehyde. The premise of safety is that the release limits meet the standards. Next Xiao Bian introduced furniture formaldehyde content standards.

Furniture formaldehyde content standard

1, the People's Republic of China national standard "solid wood composite floor" provides: A type solid wood composite floor formaldehyde emission is less than and equal to 9 mg / 100 grams; B solid wood composite floor formaldehyde emission is equal to 9 mg -40 mg / 100 grams.

2. The “Technical Requirements for National Environmental Labeling Products--Artificial Wood Panels” stipulates: The formaldehyde emission in artificial panels should be less than 0.20 mg/m3; the formaldehyde emission in wooden floors should be less than 0.12 mg/m3.

3. The national standard of the People’s Republic of China “Standard for the Sanitization of Formaldehyde in Indoor Air” stipulates that the maximum allowable concentration of formaldehyde in the air in the room is 0.08 mg/m3. European E1 environmental protection standard is: formaldehyde content ≤ 9mg/100g. E0 level environmental protection standard is: formaldehyde content ≤ 3mg/100g. However, China's current E0 environmental protection standard is: formaldehyde content ≤ 5mg/100g. E1 grade is ≤15mg/100g. In Europe, wood products are divided into three levels according to formaldehyde emission: E1 (formaldehyde content less than 10mg/100g), E2 (formaldehyde content less than 30mg/100g), and E3 (formaldehyde content less than 60mg/100g).

How to detect formaldehyde content

1. The reaction of mobilizing plants can also detect formaldehyde to a certain extent. For example, plants withered and died. This happened just after moving into a new house. The pets who are raised are sick, do not eat food, have low resistance, and have low vitality. They always like to stay quiet. If such a situation occurs, and your family has similarly low resistance, it can basically confirm that your new home is problematic.

2, for how to detect formaldehyde content, detection of formaldehyde is mostly using physical and chemical methods, this is the most sophisticated method, but also the method used by third-party testing companies, most people are incapable of using. Detection methods include: AHMT spectrophotometry, phenol reagent spectrophotometry, gas chromatography electrochemical, sensor method.

3, according to their own feelings to make judgments, for example, the family moved into new homes after the collective cold, immunity is low, easy to headache dizzy. Reduced energy is easy to wear out. It has a pungent odor, especially if you feel tears in your eyes when you are near a piece of furniture. At this time, as soon as possible to master how to detect formaldehyde content, do more sophisticated inspections, and maintain good indoor ventilation.

Editor's summary: The formaldehyde content standard for furniture is introduced here. I hope to help everyone. If you want to know more related information, you can pay attention to this website information.
