1 Scope
This standard specifies the safety requirements for emergency lighting fixtures using incandescent lamps, tubular fluorescent lamps and other gas discharge lamps. The emergency power supply voltage does not exceed 1000 V. When reading this standard, refer to the relevant chapter of GB 7000.1.
This standard does not include explosion-proof emergency lighting fixtures [see GB 3836.183 (neqIEC 79)], nor does it include the effect of non-emergency voltage reduction on lamps equipped with high-pressure gas discharge lamps.
Note: Some emergency lighting fixtures can operate at normal supply voltages during non-emergency periods.
2 General test requirements
Apply the test described in the corresponding chapters of GB7000.1 in Chapter 0 of GB 7000.11996 (idtIEC 5981:1992) in the order listed in this standard.
When testing an emergency luminaire in accordance with the requirements of this standard, the test is limited to those components of the luminaire used for emergency lighting. The parts of the luminaire that are only used for normal lighting shall comply with the requirements of the corresponding luminaire standards (for example, if the luminaire is embedded, it shall be tested in accordance with the requirements of the embedded luminaire standard).
If some parts of the self-contained emergency luminaire are close to the main components of the luminaire (within 1 m), the various methods of including all internal parts of the luminaire shall meet the relevant requirements of this standard.
3 definition
This standard uses the definitions of GB 2313 (idtIEC 920:1990), GB 7000.1 and GB 10682 (idt IEC81:1984), and also uses the definitions in IEC 924 and IEC925, in addition to the following definitions:
1) Emergency lighting emergency lighting
Illumination used in normal lighting failures, including evacuation and backup lighting.
2) Evacuation lighting escape lighting
A type of emergency lighting used to ensure that evacuated signs are effectively identified and safely used at all times during normal lighting or when emergency lighting is required.
3) Standby lighting standby lighting
A type of emergency lighting that enables normal activities to continue or be safely terminated.
4) Continuous emergency luminaire maintained emergency luminaire
A luminaire in which the emergency lighting source in the luminaire operates only during normal lighting or when emergency lighting is required.
5) Non-continuous emergency lighting nonmaintained emergency luminaire
A luminaire in which the emergency lighting source in the luminaire only works when the normal lighting supply fails.
6) Combined emergency lighting combined emergency luminaire
Emergency lighting fixtures with 2 or more light sources, at least one of which is powered by an emergency lighting source and the other sources are powered by a normal lighting source. Combined emergency lights are either continuous or non-continuous.
7) Self-contained emergency light fixture selfcontained emergency luminaire
A continuous or non-continuous emergency lighting fixture, all components, such as batteries, light sources, control components, and devices that may provide testing and inspection, are contained in or near the fixture (within 1 m).
8) Central power supply luminaire centrally supplied luminaire
A continuous or non-continuous luminaire powered by a central emergency power system that is not included in the luminaire.
9) Composite self-contained emergency light fixture compound selfcontained emergency luminaire
A self-contained emergency lighting fixture provides emergency power for auxiliary lamps, in addition to providing continuous or non-continuous emergency lighting to provide emergency power.
10) Auxiliary lighting satellite luminaire
A luminaire that derives continuous or non-continuous emergency power from a composite self-contained emergency luminaire.
11) Control unit controlunit
It includes a power conversion system, a battery charging device, and sometimes a component or components of a test device. For tubular fluorescent lamps, there can also be an inverter and ballast in this assembly.
