More and more families began to lay the ground to warm, resulting in a multi-layer parquet needs increased significantly. In fact, in Europe and the United States developed countries and Japan, multi-layer parquet is widely used in the family, and their environmental standards are very high international. The following comparison of the United States, Japan, the Netherlands and other countries of the solid wood flooring standards, especially formaldehyde emission indicators.
Formaldehyde (HCHO) on human health is very great. When the indoor air content of 0.1mg / m3 when there is smell and discomfort; 0.5mg / m3 can cause eye irritation caused by tears; 0.6mg / m3 caused throat discomfort or pain; high concentration can cause nausea, vomiting, cough, Chest tightness, asthma and even emphysema; when the air reaches 30mg / m3 can immediately lead to death.
Countries on the wooden floor of formaldehyde and other harmful substances are different standards, certification is also different, such as E-class certification, the United States for wood-based panel material CARB certification (all exported to the United States of composite wood products must meet the standard, a small number of domestic enterprises such as Fidelity flooring and other brands can be adopted), as well as Japan's F-star certification and Finland's M-class certification. What is the difference between these certifications?
E-level certification; Europe and China are different
E-class certification originated in Germany, then cited as a European standard. Today, it has become known as the formaldehyde emission level mark. European standards are divided into E1, E2 two grades, E2 ≤ 1.5mg / L, E1 ≤ 0.5mg / L.
China's wood-based panels and their products, the standard system is the reference to Europe and Japan, divided into GB E2 ≤ 5.0mg / L and GB E1 ≤ 1.5mg / L two limited levels, and the provisions of GB grade E1 products can be used directly for indoor , GB grade E2-level products must be treated by finishing to indoors.
In addition, in China E0 standard is only recommended standards, rather than mandatory standards, the equivalent of the European E1 standard. But the latter is a mandatory standard, you can see the difference between the two.
US CARB certification: one of the world's most stringent wood-based panel testing standards!
California CARB standard is the United States for the plate formaldehyde release content control regulations. At present, the regulations are one of the most stringent standards for the formaldehyde emission of composite wood products and require the factory to supervise the production process of the plant in strict accordance with the regulatory requirements of the regulations. From 1 January 2009, there is no CARB certification Of the composite wood products and products containing composite wood products can not get into the United States California "green card."
It is precisely because of strict testing standards, high security, so that solid wood flooring, especially multi-layer parquet in the US market is widely used. At present, the rich profit planning international gravel, through the North American high standards of solid wood flooring products into China, so that more users adhere to the quality of access to international quality of solid wood flooring products.

Japan F-class certification:
Based on Japan's strict social security regulatory system, Japan since July 2003 on the floor, wood-based panel to launch F-class standards, this limited standard 10 years to upgrade 7 times! The latest F ☆ ☆ ☆ ☆ launch, The world's recognized home industry formaldehyde release standards and then put on a new level.
Finland M-level certification: mainly for construction
Compared to Finland, Japan's F-level certification seems to be "tolerant". Finland M-class certification in the M3 ≤ 0.15mg / ㎡, M2 ≤ 0.125mg / ㎡, M3 ≤ 0.05mg / ㎡.
M-level certification from Finland. Finland is one of the world's most recognized countries, known as the pure king of the country, at the same time, Finland is the world's highest forest coverage in one of several countries (96%), which has a sound environmental protection system , The development of environmental standards are also in Europe leading level.
M1 certification test principle is: the fourth week after the paint brushing, with a special instrument to detect the surface of organic compounds, formaldehyde, ammonia, and some carcinogenic emissions, while the random selection of the way, through the human sense of smell Feel the smell of the paint surface.
