For example, standard E0 is made in Japan and is also made according to the strictest environmental protection standards. It can be said that it is also equivalent to E( 1/2) in Europe, and it is made according to the content of formaldehyde and other harmful substances in the board.
For example, the first two standards, E 1 and E2, were produced in Germany and formulated by "Iger", and were later cited as European standards. For example, the E0 standard claimed by many domestic companies does not exist in Europe, and the highest standard in Europe is also E( 1/2).
If the environmental protection standard in China is 10-30mg/ 100mg, it is equivalent to E2 standard. E 1 level "completely harmless to people and animals without treatment".
Generally speaking, the grade of environmentally-friendly floor refers to E0 floor-"refers to a healthy and environmentally-friendly floor with formaldehyde content less than 0.5 mg/L. The reason why it is healthy and environmentally friendly is that the formaldehyde content of 0.5 mg/L is already a very safe numerical standard.
According to the relevant data, we should know that the formaldehyde content of the drinking water we use is 0.9mg/l, which means that the formaldehyde content of E0 floor is less than that of drinking water, so we can use this floor with confidence.
E 1 is a national mandatory health standard and a mandatory "safety standard line". E0 floor uses high-quality logs for fiber separation and extraction, and also adopts pollution-free and environmental protection technology. E0 environmental protection standard is the highest detection standard of formaldehyde emission in China.
