F4 Star Environmental Protection Standard

The qualified products are E 1 grade, and E0-grade products release less formaldehyde. According to this standard, the formaldehyde emission of E 1 floor is within 1.5mg/l, and that of E0 floor is within 0.5mg/l, which is much lower than that of E 1 floor. "The China standard is referred to as the national standard, and the European environmental protection standard is referred to as the European standard. The national standard E 1≤0.5mg/L, while the European standard E 1. The global environmental protection index in Europe is "CE-E 1". European standard and national standard are two completely different standard systems. First of all, their writing styles are different. The national standard is E 1 and the European standard is E 1. Secondly, their labeling units are different. The China standard is "mg/L" and the European standard is "ppm". Third, their implementation systems are different. The national standard is "GB/T 18 102-2007" and the European standard is "EN 13392". The products that meet the European standard E 1 are detected by China method, and the formaldehyde emission is far lower than the standard of E0≤0.5mg/L in China.

It is suggested to choose high-grade environmentally-friendly flooring, all of which meet the European standard E 1, even Finland M 1 and Japan F4 Star. The detection standard far exceeds the national standard, and it is an environmentally-friendly "composite floor" that can be used safely, saving forest resources. With more and more advanced technology, less and less formaldehyde is produced.

Composite floor is a kind of floor. However, the natural structure of the composite floor is artificially changed to achieve a floor with certain physical properties that meet the expected requirements. Composite flooring in the market often refers to reinforced composite wood flooring and solid wood composite flooring. However, the term composite floor does not exist in technical terms and national industry standards.

Floor, that is, the floor of a house or the surface layer of a floor. Made of wood or other materials. Composite floor is a kind of floor. However, the natural structure of the composite floor is artificially changed to achieve a floor with certain physical properties that meet the expected requirements. Floors are roughly classified as follows: according to the structure, there are: natural landscape geomantic flooring, solid wood flooring, laminated wood flooring, solid wood flooring, bamboo flooring, cork flooring and so on. According to the use, there are: floor for domestic occasions, floor for commercial occasions, anti-static floor, outdoor floor, floor for stage dance, floor for sports venues, floor for track and field, etc. According to the classification of environmental protection level, there are E 1 floor, E0 floor and F4 floor with JAS star environmental protection standard.
