China's man-made board and furniture manufacturing industry's only mandatory national standard "indoor decoration materials and artificial wood products and manufactured products in the formaldehyde release limit" (GB18580-2001) new standards will be formally implemented on May 1, 2018.
The specific changes of the new standard and the old standard are as follows:
1. The new version of the standard increases the formaldehyde release limit requirements, provides a formaldehyde release limit value of 0.124 mg/m3, the limit labeling is E1; the unified formaldehyde detection test method is the “1m3 climatic tank method”, and the desiccator method and the perforated extraction method are eliminated. Two formaldehyde detection methods.
2. The formaldehyde release limit value is consistent with ISO16983:2016 "wooden wood-based panels - particleboard", ISO16985:2016 "wooden wood-based panels - dry-process fiberboard" regulations, testing methods using ISO12460-1:2007 "man-made board formaldehyde emission measurement first Part: 1m3 climate chamber method, which means that China's formaldehyde emission limits and detection methods have been in line with international standards.
As for the standard of sheet metal, there are usually two levels in the market, and both E-level and F-level are foreign standards.
E-class is a common definition of formaldehyde content in sheet metal defined internationally. Now it is a unified standard for European countries.
The F grade is from Japan and is divided into four grades, which is relatively higher than the E grade standard.
It can be seen that the higher the standard, the lower the formaldehyde content. The International Organization for Standardization (ISO), the European Union, the United States, and Japan have all continuously updated the formaldehyde emission limit standards for wood-based panels and their products, and have put forward higher requirements for formaldehyde emission limits.
However, China has been using the “Limit of Formaldehyde Release in Interior Decoration Material Artificial Panels and Products” (GB18580-2001) implemented in 2001 for many years. The new standard implemented since May 1, 2018 is the only change to date.
This means that since May 1st, related products sold on the market must meet the new standards.
However, raising the standard is one thing, and the cumulative effect of formaldehyde is one thing. As long as the formaldehyde content in the sheet contains indoor air, it may exceed the standard. Consumers must not take it lightly.
