IS 15518 : Part 1 : 2004 Safety Requirements for Incandescent Lamps - Part 1 : Tungsten Filament Lamps for Domestic and Similar General Lighting Purposes

ICS 29.140.20 ETD 23

Reaffirmed 2019

1 Scope

1.1 This standard (Part 1) specifies the safety and interchangeability requirements of tungsten filament incandescent lamps for general lighting service having:

- rated wattage up to and including 200 W;

- rated voltage of 50 V to 250 V inclusive;

- bulbs of the A, B, C, G, M, P, PS, PAR or R shapes (see Note), or other bulb shapes where the lamps are intended to serve the same purpose as lamps with the foregoing bulb shapes;

- bulbs with all kinds of finishes;

- caps B15d, B22d, E12, E14, E27 or E27/51 x 39.

Note - See IS 14897 for description of the letter symbols.

Associated traditional names are:

- Pear shape = A, PS
- Mushroom = M
- Candle = B, C
- Round bulb = P
- Globular = G
- Reflector = R
- Parabolic reflector = PAR

As far is reasonably practicable, this standard is also applicable to lamps with bulbs and caps other than those mentioned above, but which serve the same purpose.

This standard specifies the method a manufacturer should use to show, that his product conforms to this standard, on the basis of whole production appraisal in association with his test records on finished products. This method can also be applied for certification purposes. Details of a batch test procedure, which can be used to make limited assessment of batches, are also given.

This standard is concerned with safety criteria only and does not take into account the performance of tungsten filament lamps with respect to luminous flux, life or power consumption characteristics. Readers should refer to IS 418 for such characteristics with respect to types normally used for general lighting service.
