FOREWORD
This Indian Standard (Part 2/Sec 1) was adopted by the Bureau of Indian Standards, after the draft finalized by
the Electric Lamps and Their Auxiliaries Sectional Committee had been approved by the Electrotechnical Division
Council.
This standard published in conjunction with Part 1 of this series. The formatting into separately published parts
provides for ease of future amendments and revisions. Additional requirements will be added as and when a need
for them is recognized.
In referring to any of the clauses of IS 15885 (Part 1), specifies the extent to which such a clause is applicable and
the order in which the tests are to be performed; they also include additional requirements, as necessary. All
Sections of Part 2 are self-contained and, therefore, do not include references to each other.
Where the requirements of any of the clauses of IS 15885 (Part 1) are referred to in this standard by the phrase
“The requirements of clause ‘n’ of IS 15885 (Part 1) shall apply”, this phrase is interpreted as meaning that all
requirements of the clause in question of Part 1 apply, except any which are clearly inapplicable to the specific
type of lamp controlgear covered by this particular part and section of IS 15885 (Part 2/Sec 1).
Additional clauses/sub clauses as applicable are given in separately.
Annexes A to K form an integral part of this standard.
This standard is published in eleven sections. Other sections are:
Section 2 dc or ac supplied electronic step-down converters for filament lamps
Section 3 ac supplied electronic ballasts for fluorescent lamps
Section 4 dc electronic ballasts for general lighting
Section 5 dc supplied electronic ballasts for public transport lighting
Section 6 dc supplied electronic ballasts for aircraft lighting
Section 7 dc supplied electronic ballasts for emergency lighting
Section 8 Ballasts for fluorescent lamps
Section 9 Ballasts for discharge lamps (excluding fluorescent lamps)
Section 10 Electronic invertors and converters for high-frequency operation of cold start tubular discharge
lamps (neon tubes)
Section 11 Miscellaneous electronic circuits used with luminaires.
The safety requirement of starting devices (other than glow starters) was covered under IS 12449 (Part 1) : 1988
‘Specification for starting devices (other than glow starters): Part 1 General and safety requirements’. Since
safety requirements of all types of lamp controlgear including starting devices other than glow starters have been
covered under a new series, IS 12449 (Part 2) : 1988 ‘Specification for starting devices (other than glow starters):
Part 2 Performance requirements’ would accordingly be revised to cover only performance requirements. After
the publication of this standard, IS 12449 (Part 1)) : 1988 shall be treated as withdrawn.
Indian standards in respect of Part 2/Secs 2, 4, 5, 6, 7, 10 and 11 will be taken up in future depending upon the need.
This standard is based on IEC 61347-2-1 (2000) ‘Lamp controlgear — Part 2-1: Particular requirements for
starting devices (other than glow starters)’ issued by the International Electrotechnical Commission (IEC).
For the purpose of deciding whether a particular requirement of this standard is complied with, the final value,
observed or calculated, expressing the result of a test or analysis shall be rounded off in accordance with IS2:1960
‘Rules for rounding off numerical values (revised)’. The number of significant places retained in the rounded off
value should be the same as that of the specified value in this standard.
