Ultraviolet germicidal lamp
1 Scope
This standard specifies the product classification, technical requirements, test methods, inspection rules, marking, packaging, transportation and storage of low-pressure mercury vapor discharge ultraviolet germicidal lamps (hereinafter referred to as "lamps").
This standard is applicable to double-capped, single-capped or self-ballasted ultraviolet germicidal lamps with or without ozone and with a peak wavelength of ultraviolet radiation of 253.7nm, which are made of quartz glass.
This standard is applicable to lamps having a power below 65W.
