Champ d’application

This standard applies to directional lights used by firemen during firefighting and rescue missions. It is not applicable to general industrial or civilian lighting equipment. Manufacturers must ensure their firemen's directional light products meet these mandatory requirements. The standard covers specific parameters for firemen's personal equipment.

Exigences techniques

The standard specifies the physical and operational requirements for firemen's directional lights. Key parameters include minimum luminance brightness, flash frequency ranges for flashing models, and continuous working time limits. Environmental durability is a core focus, requiring the equipment to withstand specific climatic conditions such as high temperature, low temperature, and constant damp heat. Additionally, mechanical environment performance is specified for vibration and shock resistance. Safety and protection requirements include minimum insulation resistance, withstand voltage performance, and enclosure protection compliance with IP65. All directional lights must also meet explosion-proof performance requirements as per GB 3836.1. Other technical specifications cover maximum mass limits, drop resistance, and directional indication performance in simulated smoke environments.

Méthodes d’essai

Testing methods include luminance brightness measurement using a brightness meter and flash frequency measurement using a stopwatch. Environmental testing follows the GB/T 2423 series for climatic and mechanical endurance assessments. Other evaluations include insulation resistance, withstand voltage, enclosure protection, drop resistance, and a simulated smoke environment directional indication test.
