Is the board of the coastal wood grade the E0 grade sheet? E0 level with E1 grade plate What is the difference?
Coastal wood sheet has E0 grade plate.
E0 / E1 / E2 and the difference:
In 2004, in the national standard (GB / T9846.1-9846.8-2004), marked the E0 ≤ 0.5mg / L limit level, E0 level is China and the international caravan board and its products in the formaldehyde emission limit The highest standards; December 10, 2001, the State Administration of Quality Supervision, Inspection and Quarantine issued a "interior decoration materials man-made board and its products in the formaldehyde release limit" (GB / T18580-2001), marked E1 ≤ 1.5mg / L limit Level, the provisions of E1-class products can be directly used for indoor; December 10, 2001, the State Administration of Quality Supervision, Inspection and Quarantine issued a "interior decoration materials, wood-based panels and their products in the formaldehyde release limit" (GB18580-2001) marked E2 ≤ 5mg / L, E1 ≤ 1.5mg / L two limited levels, the provisions of E1-level products can be used directly for indoor. E2 grade products must be finishes before they can be used indoors.
Last year, the "plywood" national standard GB / T9846.1-9846.8-2004 inside the formaldehyde limit level is divided into three levels, namely E2 ≤ 5.0mg / L, E1 ≤ 1.5 mg / L, E0 ≤ 0.5 mg / L. E1 is a national mandatory health standard, it is mandatory "safety standard line". E0 standard is the current international high health standards. Because the 0.5mg / l formaldehyde content is already a very safe numerical standard. According to the relevant data show that the formaldehyde content of drinking water is 0.9mg / l,
????In other words, E0 standard formaldehyde content is less than drinking water. Environmental protection products with high levels of natural prices should be high in the production cost is certainly high.
