Initially, the two standards E1 and E2 originated in Germany and were later adopted as European standards. China promulgated and implemented the "10 Mandatory National Standards for Limits of Hazardous Substances in Interior Decoration and Renovation Materials" on July 1, 2002, namely E1 grade and E2 grade.

China promulgated and implemented the "10 Mandatory National Standards for Limits of Hazardous Substances in Interior Decoration and Renovation Materials" on July 1, 2002, namely E1 grade and E2 grade. Currently, the national standard in China is E1 grade, and many furniture items on the market can meet this standard.
The E0 standard originated in Japan and is the most stringent environmental protection standard, equivalent to the European standard E (1/2).
The "F4 Star" originated from the laws and regulations of the Ministry of Agriculture, Forestry and Fisheries of Japan. It is actually the "F☆☆☆☆ Certification Standard" of Japan, which is the health grade of the Japanese floor standard and is regarded as the healthiest floor standard in the world. If we look at it according to the usual E1 and E0 standards, then "F3 Star" is equivalent to the national E0 standard, and it is recommended to limit the usage area. "F4 Star" is much higher than "F3 Star", and there is no limit on the usage area.
Some people say that E0 is an enterprise standard, E1 is an international standard, and E2 is a domestic standard. This is not without reason. Generally, domestic standards are a little lower than European standards. E0 and F★★★★ are currently only enforced by Japan and Finland. For other countries, they are all voluntary standards rather than mandatory ones. So, to be precise, there is no such thing as the E0 grade standard in the European market.
In the early national hygiene standards for drinking water implemented in our country, the residual limit value of formaldehyde is 0.9 mg/ L. This means that E0, as the limit value standard for indoor air, can already rival the health and safety standards of related products such as food and drinking water. The E0 health standard is the global limit for formaldehyde pollution in indoor air, even surpassing the level of food safety. The requirements are so strict that the newly issued national standard only regards it as a recommended standard for board manufacturers.
