to emergency mode
According to this GOST, flammability tests of plastic for housing parts are conducted at a temperature of 850 °C.
22.17.1 Switching from normal to emergency mode must occur when the supply voltage is not less than 0.5 of the rated value.
Switching must not occur when the supply voltage is more than 0.85 of the minimum rated value.
to emergency mode
22.16.5 Safety signals of luminaires for interior lighting must meet the following requirements in emergency mode:
1. Color must comply with ISO 3864 requirements.
In an emergency, every second counts – a timely seen evacuation sign can save people's lives.
2. Brightness of any surface of a safety color signal must be not less than 2 cd/m2 in all observation directions.
elevated temperature conditions
Luminaires must operate satisfactorily in emergency mode at an ambient temperature of 70 °C, providing at least half of the rated operating duration.
As well as by ground fault or break in the normal lighting supply network.
22.12.7. Luminaire must function normally during testing
Testing is performed by simulating supply network faults during emergency mode testing.
22.6.8 Autonomous luminaires must have batteries meeting the requirements of Appendix A
and designed for at least 4 years of normal operation.
22.6.7 Autonomous luminaires must have a built-in or adjacent device for charging the battery from the normal lighting supply network
As well as an indicator, clearly visible during operation — for example, a lamp that shows that:
1) the battery is in charging mode;
2) the electrical circuit through the filament of the incandescent lamp (if used) of emergency lighting is closed.

- 1. Fire safety – check compliance with GOST 60598-2-22.
- 2. Quality battery packs.
- 3. Service life – at least 4 years.
- 4. Availability of charging device for battery.
- 5. "Test" button and indication for operability check.
- 6. Brightness of safety color signal – not less than 2 cd/m2.
- 7. Sign templates strictly complying with ISO 3864 requirements.
