Consumer Zhong Jiawei reported to the Provincial Consumers Association that when he was buying flooring, he encountered merchants promoting so-called "edible floors". According to expert analysis, this is the merchant taking advantage of people's concern about the environmental protection of the floor. Use your own psychology to make a fuss and promote your own products. Some merchants use the method of substituting concepts to label environmentally friendly “E0”, “E1”, and “E2” as registered trademarks on woodworking boards and other building materials, misleading consumers. Relevant experts believe that "E0" cannot be registered as a trademark. According to the special provisions of Article 11 of my country's Trademark Law: "For indicators involving the function, use, quality, main raw materials, weight, quantity and other characteristics of this product Neither trademarks nor logos can be registered as goods. Article 9 of the Trademark Law stipulates that signs belonging to the rights and interests of the public cannot be registered as trademarks. The Trademark Law stipulates that registered trademarks must be distinctive and distinctive. If they are for public use The logo cannot distinguish the trademark. Since "E0" is a symbol of the formaldehyde emission limit level of wooden floors and boards, it is a public logo that everyone has the right to use. Another focus is: The "E0" trademark is not E0 flooring. Regardless of the outcome of the "E0" trademark dispute, consumers should recognize the fact that the "E0" trademark is not E0 flooring. At present, most E0 grade floors are enterprise standards, and only a few domestic production lines have them. The ability to produce this flooring, the person in charge of the Municipal Decoration Association said, the E0 level standard has been used in the national standard of plywood, which stipulates that the formaldehyde emission limit value is less than or equal to 0.5 mg/L, and the E1 level limit value is less than or equal to 1 . 5 mg/L, and the E2 level limit value is less than or equal to 5.0 mg/L. Experts remind: When purchasing "E0" flooring, firstly, check whether the manufacturer holds the technical patent certificate for "E0" flooring; secondly, Learn more about the strength of the manufacturer and see if it has the technology and equipment to produce "E0" flooring. Don't believe the so-called "edible flooring" boasted by the merchant.
