Unsaturated polyester resin buttons are not standardized. The original industry standard Z8.Y280-198 unsaturated polyester resin buttons were converted to Q/T3637-[999] through the publication of Document No. 112 of the Light Industry Administration in 1999. The content is not specified in this standard. This standard is effective as of the end of this standard. This standard is issued by the Industry Association of the State Bureau of Light Industry. This standard is issued by the National Plastic Products Standardization Center. This standard is drafted by the Yizhou Panguan Ke Group! , Guangde Organic Numbers System. This standard is the responsibility of the operator: Xi Jinping, Yang Zong: This standard wins from the date of implementation, except for the Ministry of Industry and Energy Standard Z280091989 and the lack of energy-saving trees:
