BIS CERTIFICATION FOR TUNGSTEN FILAMENT LAMPS IS 418:2004
Tungsten filament is an alloy wire comprised of tungsten and other metals. It produces light when heated to extremely high temperatures. It works on the incandescence principle. The term 'incandescent' refers to light produced by heat.
To ensure the product quality of tungsten filament lamps, the Bureau of Indian Standards (BIS) has made it mandatory for manufacturers to undergo BIS registration and obtain the BIS ISI mark before selling it in the market. Manufacturers can use the ISI Mark on their products only after obtaining a license from BIS that is granted after BIS registration. The presence of the ISI mark on a product indicates that it complies with BIS's stringent quality standards.
IS 418:2004 applies to tungsten filament incandescent lamps for general lighting service (GLS) that meet the safety requirements in Doc ET 23 (5291) and have the following characteristics:
·Rated wattage of 15 W, 25 W, 40 W, 60 W,100 W, 150 W, and 200 W
·Rated voltage 110 V, 230 V, 240 V, and 250 V, including marked voltage range not exceeding ± 2.5% of the mean voltage
·Bulbs of the A, K, M, or PS shapes
·Bulbs with clear frosted or equivalently coated finishes, or white finishes.
·Caps B22d or E27
·Lamp shell diameters shall range from 54 to 62 mm for ratings up to 100 W.
This standard specifies the performance requirements for lamps and test methodologies and procedures for ensuring compliance requirements. This procedure can be used to obtain certification. The lamps claiming compliance with this standard must meet the requirements of Doc ET 23 (5291).
REQUIREMENTS FOR TUNGSTEN FILAMENT LAMPS
1.Lamps must be designed in such a way that their performance is reliable in normal and accepted use.
2.In general, this can be accomplished by meeting the requirements of the standard. Lamps must be tested according to the test procedure.
3.Lamps must meet the dimensional requirements specified on the relevant lamp datasheet.
4.Lamps with E27 caps must meet the gauge for testing contact-making specified in datasheet 7006-50.
5.Individual lamp lumen maintenance at 75% of rated life shall not be less than the minimum value specified on the relevant lamp datasheet.
6.The lamp shall be marked with information as specified in the standard. ISI certification mark may also be marked on the lamps.
TEST REQUIREMENTS OF IS 418:2004
The following test shall be carried out for tungsten filament incandescent lamps.
·Luminous Flux Initial
·Accidentally live parts
·Protection against accidental contact in screw lamp holders
Tungsten filament lamps have been included in the mandatory ISI Certification Scheme under the IS 418:2004 standard. This product cannot be exported, imported, or sold in the Indian consumer market without the ISI Mark imprinted.
