IS 15518-1 Tungsten Filament Lamps ForDomestic And Similar General Lighting Purposes

Standard IS 15518:2004(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 by the Electrotechnical Division Council.

Standard IS 15518:2004(Part 1) covers the safety and interchangeability requirements of tungsten filament incandescent lamps for general lighting services. This standard does not specify the performance requirements, which are covered in a separate standard.

It is intended to prepare following parts of this standard as and when need arises:

– Part 2 Tungsten halogen lamps for domestic and similar general lighting purposes
– Part 3Tungsten halogen lamps (non-vehicle) which is presently covered under IS 12948:1990 Tungsten halogen lamps (non-vehicle)

Standard IS 15518:2004(Part 1) is based on IEC 60432-1(1999)’Incandescent lamps -safety specifications: Part 1 Tungsten filament lamps for domestic and similar general lighting purposes’ issued by the International Electrotechnical Commission (IEC) with the following deviations:

a) Lamps of E17 and E26 caps have not been covered as these are not in use in India;
b)Definition on reference lamp, its marking and characteristics have been incorporated; and
c)Data sheets on caps and their gauges have been included.

The data sheets given in this standard on caps and gauges have been numbered in line with IEC 60061 Lamp caps and holder together with gauges for the control of interchangeability and safety: Part 1 for Lamp caps, and Part 3 for Gauges.

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 IS 2 : 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.
