Example 1.ZW15S26W indicates a 15 W double-capped ozone-free ultraviolet germicidal lamp with a tube diameter of 26 mm.5 Technical requirements5.1 General requirements The design, structure and performance of lamps shall ensure reliable performance in normal use and not cause danger to users and the surrounding environment. Generally, the qualification is checked by conducting all the specified tests. 5.3 Glass tube The glass tube of lamps shall be transparent and clean and shall not have defects that affect the transmission of ultraviolet rays. 5.4 Lamp holder The finished lamp shall be equipped with a lamp cap that meets the corresponding light source performance standards.
