Electronic cigarettes, also known as vaping devices, are electronic delivery systems used to produce aerosols for inhalation. They resemble traditional cigarettes in appearance, smoke, flavor and feel as a nicotine delivery system. An electronic cigarette consists of three parts: a battery-powered rod, an atomizer and a mouthpiece. The atomizer, powered by the battery rod, vaporizes liquid nicotine in a pod, creating a smoke-like vapor for users to inhale, simulating the sensation of smoking.
On April 8th of this year, the national standard GB 41700-2022 for electronic cigarettes, which was centralized and revised by the National Tobacco Standardization Technical Committee (TC144), was issued. The standard will be implemented on October 1st, 2022. Section 4.1.2.1 of this standard specifies that materials in contact with the mouth, aerosols, and e-cigarette emissions must meet the requirements of standards GB 4806.1 and GB 4806.3-GB 4806.11.
The components of electronic cigarettes that can be tested according to the GB 4806 series standard include oil cups, oil cup covers, sealing plugs, oil injection plugs, silicone sealing rings, atomizer base plates, atomizer core brackets, atomizer core outer shells, outer shell connectors, oil guiding cotton, insulating silicone, heating elements, heating wires, oil separating cotton, heating wire brackets, center tubes, and mouthpieces. Based on the material of the electronic cigarette components, they can be divided into plastic molded products, metal products, rubber molded products, and paper products. Specific sanitation and inspection standards can be found in Tables 1 and 2.
