of quartz glass or other ultraviolet-transmitting glass, with or without ozone and with
an ultraviolet radiation peak wavelength of 253.7 nm.
This document applies to lamps with a nominal power of less than 58 W, excluding cold
cathode ultraviolet lamps.

5.5 Anti-ultraviolet radiation
The insulating materials used for lamp caps and lamp housings shall be resistant to
ultraviolet radiation, anti-ultraviolet aging and embrittlement. After completing the test
in 6.9, the sample shall not have any changes that weaken its safety, the anti-electric
shock performance of the insulating material shall not be reduced, the lamp cap and the
lamp cap pins shall not be loose, and the insulating material shall not be cracked, bulged
or shrunken.
5.6 Lamp dimensions
The dimensions of double-capped lamps, single-capped lamps and self-ballasted lamps
shall comply with the provisions of the corresponding model lamps in GB/T 10682,
GB/T 17262 and GB/T 17263, respectively.
5.7 Starting characteristics
