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 1 000 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 GB3 836.I-83 (neqI EC7 9)), and does not include the impact of non-emergency voltage reduction on lamps equipped with high-pressure gas discharge lamps.
Note: Some emergency lighting fixtures can operate at normal supply voltage during non-emergency periods.
2 General test requirements
Apply the test described in the corresponding chapters of GB 7 000.1 in Chapter 0 of GB 7 000.1-1996 (idtIE C5 98-1:1992) 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 GB2 313 (idtIE C9 20; 1990), GB7 000.1 and GB1 0682 (idtIE C8 111984), and also uses the definitions in IEC 924 and IEC 925, in addition to the following definitions:
1) Emergency lighting emergencyl ighting
Illumination used in normal lighting failures, including evacuation and backup lighting.
2) Evacuation lighting escapeli ghting
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, tandbyl ighting
A type of emergency lighting that enables normal activities to continue or be safely terminated.
4) Continuous emergency lighting maintainede mergencylu minaire
A luminaire in which the emergency lighting source in the luminaire operates during normal lighting or when emergency lighting is required.
5) Non-continuous emergency lighting non-maintainede mergencylu minaire
A luminaire in which the emergency lighting source in the luminaire only works when the normal lighting is supplied.
6) Combined emergency lighting combinede mergencylu minaire
An emergency lighting fixture with two or more light sources, at least one of which is powered by an emergency lighting power source, and the other light source is powered by a normal lighting power source. Combined emergency lights are either continuous or non-continuous.
7) Self-contained emergency light fixture self-containede mergencylu minaire
A continuous or non-continuous emergency lighting fixture with all components, such as batteries, light sources, control components, and devices that may provide testing and inspection, contained in or near the fixture (within 1 m).
8) Central power supply lamps centrallys uppliedl uminaire
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 lighting compounds elf-containede mergencylu minaire
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.
To) Auxiliary lighting satellitelu minaire
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 may be an inverter and ballast in the assembly.
12) Normal power failure normalsu pplyf ailure
Normal lighting can no longer provide a state of minimum illumination for emergency evacuation purposes, at which point emergency lighting must begin to operate.
13) Luminaire rated lumen output ratedl uminairelu meno utput
The lumen output of the Im in light after a normal power failure as specified by the luminaire manufacturer and shall continue until the end of the rated working time.
14) Rated working time: atedd urationo fo peration
The time required to provide the rated lumen output as specified by the manufacturer. This working time does not include the first minute after a normal power failure.
15) Normal state normalm ode
The self-contained emergency luminaire is in a state of work preparation during normal power supply. In the case of a normal power failure, the luminaire automatically switches to an emergency state.
16) Emergency status. Mergentm ode
In the event of a normal power failure, the self-contained emergency luminaire is illuminated by the internal power source.
17) Rest state restm ode
In the time when the normal power supply is stopped, the self-contained emergency luminaire is in the extinguished state.
