environmental strength, varegoethe enters the "star" era
when buying cabinet products, people often hear a concept: Japan's f☆☆☆ (F4 star) standard is safer. Why does F4 star give consumers a sense of security in environmental protection? We have to start from its origin.

as early as 1980, Japan formulated the man-made Board formaldehyde release limit standard with reference to the European standard. However, in the late 1990 s, the Japanese government found that if European detection methods were used, indoor formaldehyde concentration exceeded the standard quite seriously, because the whole house in Japan is man-made Board, the Japanese government began to study the "New House syndrome" again ".
From July 1, 2003, the Japanese government requires all local wooden products and imported building materials to reach F4 star, that is, the formaldehyde emission is less than 0.3mg/L. The detection method is not only to improve the value, but also to detect the compliance of the detection method, the detection area and the factory environment, so as to strictly avoid the use of special means to pass the detection and obtain certification for products that do not conform to the regulations.

therefore, F4 star is not only the health level with the highest environmental protection standard in Japan, but also considered as the best environmental protection standard in the world. This plate upgrade F4 star standard means that the health index of varegoethe plate has reached the highest grade standard widely considered by the world.
About Japanese f☆☆☆☆ detection
compared with the national standard E1 grade environmental protection detection, although the detection methods of the two standards are different, the Japanese f☆☆☆ detection is more strict, not only is the requirement for formaldehyde, environmental protection certification is also carried out for the whole production system of the factory: raw materials, production processes and finished products.

balance processing
simply put, it is to release some formaldehyde from the plate first to reach the equilibrium state of the plate release.
Why do we need to balance?
1. The purpose of detection methods in various countries is to detect the real formaldehyde emission. After the equilibrium treatment, the real formaldehyde release can be simulated.
2. Because formaldehyde is an important and affordable chemical raw material, national standards have a certain tolerance for formaldehyde, as long as the formaldehyde content is safe and harmless.
3. It can also be seen from the balance treatment that ventilation after decoration is very necessary.
Number of groups
the national standard uses two experimental groups to avoid errors.
However, Japan's F4 star is much more rigorous, and three experimental groups have been built with smaller errors.
Time
the faster the detection time, the better. The content released in the previous day of the plate is much higher than that released seven days later. New national standard E1, wait until the formaldehyde release is stable before measuring, it will take at least 7 days, up to 28 days.
Japanese standards are much stricter. One day after the plate was put into the testing instrument, formaldehyde content began to be tested.
Numerical comparison
the new national standard E1 is measured by the climate box (chamber) method, and the standard value is 0.124mg/m³
japan F4 star uses drying box method, and the unit of the detection value is different from E1, but some literatures also give indirect transformation formula. The value detected by climate box method is about 0.2 times, and the value detected by drying box method. That is:
f☆☆☆☆, change to mg/m³ unit, that is, 0.06mg/m³
for the health of your family
the upgrade of Japanese f☆☆☆☆ environmental protection certification of this plate is a witness of varegoethe's adherence to the environmental protection concept of "thinking for the health of your family". It is an encouragement and an incentive.
