This British Standard has been prepared under the direction of the Light Electrical Engineering Standards Policy Committee and is the English language
version of EN 60730-2-3:1992 Automatic electrical controls for household and
similar use — Part 2-3: Particular requirements for thermal protectors for ballasts for tubular fluorescent lamps, including amendment A1:1998 and Corrigendum
March 2001, published by the European Committee for Electrotechnical Standardization (CENELEC) It was derived by CENELEC from IEC 60730-2-3:1990, including amendment 1:1995, published by the International Electrotechnical Commission (IEC)
CENELEC corrigendum March 2001 changes the latest date of withdrawal of conflicting national standards in the EN foreword and the foreword to
amendment A1
The CENELEC common modifications have been implemented at the appropriate places in the text The start and finish of each common modification is indicated
in the text by tags
Parts of the original IEC text that have been modified by CENELEC have been quoted in National annex NA
The start and finish of text introduced or altered by amendment is indicated in the text by tags !" Tags indicating changes to IEC text carry the number if the IEC amendment For example, text altered by IEC amendment 1 is indicated
by !"
The foreword of EN 60730-2-3 makes reference to the “date of withdrawal”, dow,
of the relevant national standard In this case the relevant national standard is
BS 3955 which will cease to be applicable to thermal protectors within the scope
of BS EN 60730-2-3 on 1 January 1997 Certification and marks will not be awarded after this date with respect to BS 3955 However such certification and marks already awarded may continue to apply to production
until 1 January 2001 BS 3955 will be progressively amended to delete specific controls at the dates of withdrawal agreed
This British Standard is to be read in conjunction with BS EN 60730-1:1992
General requirements, which it supplements or modifies The many references to
Part 1 should be read as references to BS EN 60730-1, which is the English language version of EN 60730-1 which was derived from IEC
Publication 730-1:1986
A British Standard does not purport to include all the necessary provisions of a contract Users of British Standards are responsible for their correct application
Compliance with a British Standard does not of itself confer immunity from legal obligations.

1 Scope
This clause of Part 1 is replaced as follows:
1.1 This standard applies to the evaluation of thermal protectors for ballasts for tubular fluorescent lamps.
!This part applies to thermal protectors using NTC or PTC thermistors, additional requirements for
which are contained in Annex J."
Requirements concerning the testing of the combination of ballast and thermal protector are given in EN 60920.
1.1.1 This standard applies to the inherent safety, to the operating values, operating times, and operating
sequences where such are associated with equipment safety and to the testing of thermal protectors used
to protect ballasts for tubular lamps from overheating
This standard applies to thermal protectors for ballasts within the scope of EN 60920
Thermal protectors covered by this standard may be suitable for ballasts for other discharge lamps.
Throughout this standard the word “protector” means “self-resetting thermal ballast protector”.
1.1.2 This standard is not applicable to other means used to protect ballasts.
1.1.3 This standard does not apply to a manual device for opening the circuit.
1.2 This standard applies to protectors for use with ballasts for use on a.c supplies up to #690 V$
at 50 Hz or 60 Hz
1.3 This standard does not take into account the response value of an automatic action of a control, if such
a response value is dependent upon the method of mounting the control in the equipment Where a
response value is of significant purpose for the protection of the user, or surroundings, the value defined in the appropriate household equipment standard or as determined by the manufacturer shall apply
2 Definitions
