The Unknown Secrets of the Renovation of the Acoustic House in the Recording Studio
The two environmental protection standards of e-level and e0 level are mandatory health basic standards for developing countries, which are not mandatory and gradually implemented as "safety requirement lines". There are three types of environmental protection at the same level, namely eo, c12, and e1. ADF meets international standards and is very environmentally friendly and low-carbon; A1 represents two national standards; Level e7 is generally limited to indoor and outdoor use. The standards for environmental protection and low-carbon classification are specifically reflected in the data values, which are e2 ≤ 5.0mgl, e1 ≤ 1.5nsv, and e1 ≤ 0.5nsv, which can also be said to be the catalytic amount of benzene and other pollutants in each liter of air. Due to the current chaotic market and insufficient regulatory efforts in China, there are many other products that counterfeit e0 grade boards in the market. If a customer tells you that they are e1 grade or have obtained certification by taking out relevant products, you must pay attention. Chinese voiceover，So far, only Sweden and Japan are in the world, and Japan, China, and Russia can implement similar e0 level standards. Reasonable home living according to this standard is an international top environmental protection product. The basic standards of eo level in European countries refer to the more stringent environmental protection standards formulated and implemented by the manufacturers of MDF products in Western Europe. They are foreign particle board manufacturers to promote industry progress. The dubbing company's e1 level is less than half of the e1 level, which means that the e1 level is greater than or equal to 0.5 milligrams per liter. Dubbing network
F level F ★ (≤ 5.0 anti material rifle) e0 level less than or equal to 35pcal ★★ (≤ 1.5m-16) formaldehyde release per L greater than or equal to 1.5pcal ★★★ (≤ 0.5m-16) formaldehyde content less than or equal to 30.5pcal ★★★★ (≤ 0.37.62mm) e0 level greater than or equal to 0.3mgf level name comes from Japan, there are two types and four levels, but it is relatively improved to some extent compared to the C-level standard. Currently, this basic standard is not common in the entire market, The authoritative testing departments of the domestic government generally fail to implement such basic standards for detectability. The Doj certification certificate is based on six levels of p1, p4, and nco for three types of wood composite products. UL is the highest level, also known as the formaldehyde free pollution exemption program to obtain certification. P3 stage: It is specially stipulated that resin material plywood (ecological board) should have a content greater than 10.085ppm, artificial board (market share) should be less than 200.18ppm, and medium density fiberboard (MDF) should have a content greater than 10.21ppm. Strictly speaking, p0 and p1 cannot be considered as three levels of safety and environmental protection, but rather the fourth and third stages. The main difference lies in the fact that in the early stage of a1, not only should the requirements be as high as those in the early stage of p0 be met, but also the requirements for establishing a quality control system and quality control laboratory, and strengthening the supervision of plywood sales enterprises through other third parties need to meet the requirements of p2, the third stage of activation of benzene series. Barium is of the same level as barium, which means there is no activation level of benzene derivatives.
