IEC 60598-2-14 pdf download – Luminaires – Part 2-14: Particular requirements – Luminaires for cold cathode tubular discharge lamps (neon tubes) and similar equipment
14.1scope
This part of lEC 60598 applies to luminaires for cold cathode tubular discharge lamps andsimilar equipment，operating on a no-load rated output voltage over 1 00o v but notexceeding 10 oo0 v, mainly used for general lighting, for indoor or outdoor applications andfor supply voltages up to 1 ooo v.
NOTE Iln Japan,the output voltage of 15 000 v is acceptable.
lt covers luminaires incorporating luminous-discharge tubes and supply units，of fixed orportable type,supplied by high，mains or ELV voltages by transformers，inverters orconverters.
This standard does not cover luminaires for luminous-discharge tubes operating at ratedvoltages not exceeding 1 000 v(pre-heated cathodes), for which reference is made to therelevant part 2 of lEC 60598,and luminous discharge tube luminaires to be assembled in siteas an electrical lighting system, for which regional wiring rules apply.
This standard is read in conjunction with those sections of Part 1 to which reference is made.

14.3General test requirements
The provisions in Section 0 of lEC 60598-1 apply.
NOTE This section of lEC 60598-1 covers complete products，on which routine tests according to Annex Q ofPart 1 can be made.
14.4Definitions
For the purposes of this document,the definitions given in Section 1 of lEC 60598-1 apply.together with the following.
14.4.1
luminous-discharge tube
tube，or other vessel or device，which is constructed of translucent material，hermeticallysealed, and designed for the emission of light arising from the passage of an electric currentthrough a gas or vapour contained within it
NOTE The tube may be with or without a fluorescent coating.14.4.2
no-load rated output voltage
maximum rated voltage between the terminals of the output winding(s) of the transformer,asin 2.8 of IEC 61050, or maximum rated voltage between outputterminals ofinverters/converters as in 3.2 of lEC61347-2-10
14.4.3
insulating sleeve
envelope designed to be placed over the exposed high-voltage connections at tube electrodesor over cable-end insulators
14.4.4
earth leakage protective device
device which will remove the output power from one or more control gear(s) in the event of ashort circuit between any relevant part of the output circuit and earth
NOTE The device may be in two parts,a 5en5or and a protective switch (see 14.7.3), or may be combined in units(either insids or outsilde controll gears.
14.4.5
open-circuit protective device
device which will remove the output power from one or more control gear(s) in the event of aninterruption of the secondary high voltage circuit
NOTE The device may be in two parts, a sensor and a protective switch (see 14.7.4),or may be combined in oneunit.
14.4.6
open-circuit condition
a disconnection or lamp fault in the output circuit that causes either the load current of , or themains supply current to，the control gear feeding the lamp circuit to fall below the respectiveshut-down current limit
14.4.7
shut-down current limit
secondary load current of a transformer at which an open-circuit protective device operates
NOTE Although the shut-down current limit is specified in terms of the current flowing in the output cireuit, the
measuring the current reflected into the primary winding of the transformer or measuring a change in circuit powermanufacturer of the device may measure this by other than direct means.Suchmeans might include，e.g.factor.
14.4.8sensor
part of a protective device which detects the presence of a secondary earth fault and/or anopen circuit condition and provides a signal to operate the protective device
