What is the normal value of formaldehyde?

Formaldehyde is a substance that is harmful to the human body, so you must not move in immediately after your house is renovated. You must release all the formaldehyde in the room before you can move in. Otherwise, formaldehyde is very harmful to the human body. You must be cautious and pay attention to it. Open the windows in the room for ventilation every day. Many people don’t know what the normal value of formaldehyde is. What is the normal value of formaldehyde? Let’s take a look at it next.

1. What is the normal value of formaldehyde?

During house acceptance, formaldehyde becomes the top priority. The standard value for indoor formaldehyde detection is actually determined according to different materials. Generally, the indoor formaldehyde concentration index cannot exceed 0.08 mg per cubic meter.

2. The floor decoration is generally divided into two types

The first type: The formaldehyde concentration in the laminate flooring cannot exceed 0.9 mg.

The second type: The formaldehyde concentration of the floor can only be between 0.4-0.9 mg and must not exceed the standard.

It is particularly important to note that the formaldehyde concentration in artificial floors cannot exceed 0.2 mg per cubic meter.

3. About indoor air

According to the "Sanitary Standards for Formaldehyde in Indoor Air" in my country's national standard:

1. The maximum allowable concentration of formaldehyde in indoor air is 0.08 mg/cubic meter (0.08 mg/m3).

If the formaldehyde content exceeds 0.08 mg, the house is considered unqualified.

4. About indoor floor selection

According to the national standard of "Solid Wood Composite Flooring" in my country:

Class A: The formaldehyde emission of solid wood composite flooring is less than or equal to 9 mg/100 g (9mg/100g);

Class B: The formaldehyde emission of solid wood composite flooring is greater than 9 mg to 40 mg/100 g (9mg~40mg/100g). If it is found that it exceeds the national standard, it can be reported.

5. About the selection of artificial wood panels

According to the "National Environmental Labeling Product Technical Requirements for Artificial Wood Panels" in my country's national standard:

1. The formaldehyde emission contained in artificial boards should be less than 0.20 mg/m3;

2. The formaldehyde release in wooden floors should be less than 0.12 mg/cubic meter (0.12 mg/m3). If you find that formaldehyde exceeds the standard, you can report it in time.
