T/CEEIA 708-2023 Technical specification for LED emergency lighting and evacuation indicator for explosive environments

Scope

Scope: This document specifies the terms and definitions, classification, technical requirements, test methods, inspection rules, marking, packaging, transportation, storage, and user manuals for LED emergency lighting and evacuation indicator lamps used in explosive environments (hereinafter referred to as "lamps"). This document applies to emergency lighting lamps and emergency evacuation indicator lamps using LED light sources, with AC power supplied at a rated voltage of 220 V and a frequency of 50 Hz, or DC power supplied at a rated voltage of 250 V (emergency lighting centralized power supplies may use a rated voltage of 380 V). This document also applies to lamps connected to intelligent control technology systems (e.g., integrated fire linkage functions, systems with a separate local area network, RS232/RS485 interfaces, CAN/Modbus protocol connections to control technology systems; power line carrier communication control technology systems; wireless signal or IoT connected control technology systems, etc.). This document does not apply to Class I lamps installed in coal mine gas explosive environments, as well as emergency lighting controllers and emergency lighting centralized power supply products.
