FOREWORD
This Indian Standard ( Part 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 bythe Electrotechnical Division
Council.
The lamps covered under these standards are self ballasted lamp. Such lamps incorporates permanently enclosed
element that are necessary for starting and for stable operation and which does not include any replaceable or
interchangeable parts.
These lamps are considered asenergy efficient lamps and are commonly known as compact fluorescent lamps.
The need ofpreparing this standard hasbeen realized onlyafler ensuring the manufacturing potential and demand
inthe country.
There are other types of compact fluorescent lamps, which are the discharge lamp of the low-pressure mercury
typehaving singlecapforoperations onexternalcircuitswithinternalorexternalmeansofstarting. Therequirements
of such lamps will be covered inaseparate standard.
This standard hasbeen dealt within twoparts, oneexclusively onsafetyrequirements andtheother onperformance
requirements.
I Thisstandard isbased onIEC60968 ( 1988)‘ Selfballasted lampsforgeneral lighting services, safetyrequirements’

a) Schedule of type test and acceptance test have been incorporated;

d) Conditions of compliance incorporated;
e) Lamps of rating up to 26 Ware only covered; and
