Environmental protection grade standards and purchasing tips for boards

When decorating, people often talk about "aldehyde" in fear. As an important part of home decoration, board materials are also one of the sources of formaldehyde in the decoration process.

While formaldehyde is harmful, it has a threshold hazard, becoming harmful only after exceeding a certain concentration. my country's latest indoor air quality standards stipulate that the one-hour average formaldehyde concentration should be less than or equal to 0.080 mg/m³.

There are many environmental protection standards and grades for boards on the market, which dazzles consumers, such as E1, E0, F4, NAF, ENF, etc. If you want to buy safe and environmentally friendly boards that suit you, you must first understand the environmental protection level of the boards.

Popular Science of Plate Knowledge

There are currently four major mainstream environmental protection standard grades for panels:

European standard E-level, new national standard E-level, Japanese F-star, and US CARB level certification.

European standard E grade is currently the most popular and well-implemented quality technical standard in the world. The formaldehyde emission content standards it stipulates are as follows:

E1≤0.5mg/L

E2≤1.5mg/L

The new national standard E-grade is divided into three levels: E1, E0, and Enf. The formaldehyde emission content standards are as follows:

E1≤0.124mg/m³

E0 level≤0.050mg/m³

ENF level≤0.025mg/m³

The new national standard E1 level is my country's mandatory national standard and the entry standard for environmentally friendly panels; the ENF level is the highest environmental protection standard of the current new national standard.

Japan's F-star standard is divided into 4 levels, and the formaldehyde emission content standards are as follows:

F☆ (≤5mg/L)

F☆☆ (≤1.5mg/L)

F☆☆☆ (≤0.5mg/L)

F☆☆☆☆ (≤0.3mg/L)

The higher the F star rating, the lower the formaldehyde emission. F☆☆☆☆ is the highest level in Japan's environmental protection standards.

The US CARB certification is divided into three levels:

P1, P2, NAF levels.

The highest grade is NAF, also known as formaldehyde-free exemption certification. The formaldehyde emission standard of NAF grade is 0.04ppm.

The four environmental standards use different testing methods and conditions, so comparisons cannot be made based solely on the data. However, research indicates that the Japanese F☆☆☆☆ formaldehyde emission limit of 0.3 mg/L is approximately equivalent to the European standard climate chamber test value of 0.04 mg/m³.

Of the four environmental protection grade standards, the new national standard E-grade is the most widely used in the Chinese market and was officially implemented on October 1, 2021. The new national standard E-grade adopts the "national standard 1 cubic meter climate chamber method" which is highly similar to the "European standard climate chamber method EN 717-1" of the European standard E-grade, and also has very strict requirements on formaldehyde emission limits.

Domestic panels that meet the new national standard E1 are qualified environmentally friendly products and are allowed to be used for interior decoration. E0 and ENF grade panels meet the more stringent formaldehyde emission standards and can well meet the requirements of indoor air quality standards.

Tips for purchasing boards

1. It is best to purchase panels through formal channels and choose panels produced by big brands. This is because big brand companies generally have more mature production and processing technology, more advanced equipment, more stringent quality inspection systems and better after-sales guarantees;

2. When purchasing environmentally friendly panels, pay attention to the environmental grade mark of the panels. It is best to see the merchant's test report. You can ask the dealer for the panel's quality inspection report for review;

3. The space of the house we live in is fixed. The accumulation of formaldehyde content will also cause environmental protection to exceed the standard. When purchasing building materials, we should choose more environmentally friendly materials. Secondly, we should also pay attention to the amount of building materials used.

4. In addition to environmental protection, the color of the board is also one of the key research and development directions of board companies. There are many board colors available on the market. You can choose the board color according to the decoration style of your house and your own preferences.

Crown Plate

Ushering in the ENF-level environmental protection era

Crown insists on creating healthy and environmentally friendly home furnishing panels and has established a standardized production process and a strict quality control system.

Each type of board is refined through more than thirty processes, and the original three-time formaldehyde purification process greatly improves the environmental friendliness of the board.

After years of research, development, and testing, Crown has officially launched ENF-grade sheet materials, achieving environmental performance that meets or exceeds ENF standards. Crown ENF-grade sheet materials utilize environmentally friendly adhesives, with strict environmental performance controls at every stage, from substrate selection to processing.

Crown products are of worry-free quality

The board is made of an optimal base material and high-quality decorative paper as the fabric. It is made through processes such as cold pressing, hot pressing, sanding, and curing. It has high strength, good flatness, strong stability, and rich colors.

The company submits its products to authoritative testing departments for inspection several times a year and cooperates with local institutions to conduct random inspections of product quality to ensure that the actual measured performance indicators of the products are at the leading position in the industry.

After 24 years of dedicated development, Crown has become a leading company in the artificial board industry. In the future, Crown will continue to explore and innovate, striving to create healthy and environmentally friendly home board products that consumers can trust.
