UV radiation source as UV killer The core component of sterilization products is used to achieve the purpose of sterilization and disinfection. GB/T 19258 "Ultraviolet radiation source for sterilization" aims to standardize the The safety requirements and performance requirements of ultraviolet radiation sources are planned to be composed of 5 parts. ---Part 1.Low-pressure mercury vapor discharge lamps. The purpose is to standardize the production of low-pressure mercury vapor discharge hot cathode ultraviolet germicidal lamps. Product classification, technical requirements, test methods, inspection rules and markings, packaging, transportation and storage. ---Part 2.Cold cathode low pressure mercury vapor discharge lamps. The purpose is to standardize low-pressure mercury vapor discharge cold cathode ultraviolet sterilization Product classification, technical requirements, test methods, inspection rules and markings, packaging, transportation and storage of lamps. ---Part 3.UV excimer lamp. The purpose is to standardize the product classification and technology of 222nm ultraviolet KrCl excimer lamps Requirements, test methods, inspection rules and markings, packaging, transportation and storage. ---Part 4.UV germicidal lamp based on photocatalysis.

The discharge produces a wavelength of Ultraviolet radiation mainly at 253.7nm. Note. Its ultraviolet radiation can kill bacteria and viruses. Effective sterilization and disinfection require a certain ultraviolet dose. The ultraviolet dose refers to the amount of radiation received per unit area. of ultraviolet energy. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 19258.2-2023_English be delivered?Answer: Upon your order, we will start to translate GB/T 19258.2-2023_English as soon as possible, and keep you informed of the progress.
