Overview of the core content of the standard
GB/T 7000.222-2023 replaces GB 7000.2-2008, and specifies the special requirements for emergency lighting fixtures with a power supply voltage ≤1000V, including classifications such as continuous, non-continuous, and self-contained, and adds ESS power supply types (such as lithium batteries, EDLC capacitors) and brightness contrast measurement methods.
Definition of key terms
Terms Definition Self-contained emergency luminaire Independent system including light source, control unit and ESS power supply, with maximum wiring length of 1m Rated emergency working time The shortest time for continuous provision of rated luminous flux as declared by the manufacturer (e.g. 30min/60min) PELF/PELSF Calculation parameters of minimum luminous flux of actual emergency light source, involving EOF factor of LED
Comparison of technical requirements (new and old standards)
Main changes:
- New ESS types: lithium iron phosphate, lithium titanate batteries and EDLC capacitors (Appendix A)
- Response time in high-hazard areas extended from 0.25s to 0.5s (Article 17.3)
- Mandatory internal lighting safety signs comply with ISO 3864-4 photometric requirements (Article 17.5)
Test requirements
Durability test: 390h cycle test (10×36h positive/emergency mode + 30h charging), 50 power switch impact tests (Article 13.1)
Photometric test: According to CIE 121 SP1 and CIE S025, luminaires in high-hazard areas must reach 100% light output within 0.5s (Article 17.3)
Implementation suggestions
1. The marking of Self-contained luminaires must include the ESS type, replacement cycle (4 years) and charging voltage range (Article 6.7)
2. Lithium battery systems must provide UN38.3 or IEC 62133-2 certification documents (Appendix A.7)
3. When installed on a rail system, an additional anti-misadjustment locking device must be added (Article 7.23)
