New Standard from Last Update.

1. SCOPE

This standard (Part 2) specifies the performance requirements, together with the test methods and conditions, required to show compliance of double-capped LED linear retrofit and conversion lamps, with G5 and G13 caps suitable for use in luminaires and also intended for replacing fluorescent lamps with the same caps, having:

a) a rated power up to 40 W;

b) rated a.c. voltage of up to 250 V at 50 Hz or a rated d.c. voltage of up to 250 V;

c) nominal lengths from 300 mm to 1 500 mm.

NOTES

1 Double-capped LED Linear lamp(s) are commonly known as LED tube light(s).

2 Where in this standard the term ‘LED Lamp(s)’ is used, it is understood to stand for ‘double-capped LED Linear lamp(s)’, except where it is obviously assigned to other types of LED lamps.

3 LED Lamps supplied with external controlgear are covered under the scope of this standard provided that the controlgear meets the requirements of relevant Indian standard i.e. IS 15885 (Part 2/Sec 13).

4 The manufacturer or responsible vendor shall provide recommended controlgear for testing purposes. Failure of the LED Lamp and/or controlgear shall be considered as the failure of the LED lamp together with the controlgear.

The requirements specified in this standard are applicable for LED lamps for domestic and similar general lighting services. Additional requirements may apply for LED lamps intended for use in other applications.

The requirements of this standard relate to type and acceptance testing.

This standard covers LED Lamps that intentionally produce white light, based on inorganic LEDs. This standard does not cover LED Lamps that intentionally produce tinted or coloured light nor does it cover OLEDs.

This standard specifies test requirements for a maximum rated life (declared) of up to 50 000 h. The verification of manufacturer’s life time claims beyond rated life of 50 000 h cannot be made in a sufficiently confident way, because projecting test data further in time is not available.

It can be expected that LED lamps, which comply with this standard will start and operate satisfactorily at voltages between 90 percent and 110 percent of rated supply voltage and at an ambient air temperature between -10°C and 50°C and in a luminaire complying with IS 10322 (Part 1).

If the manufacturer or the responsible vendor claims suitability for operation at different conditions (for instance, at higher voltage, temperature or humidity) then:

a) Lamps shall be tested under claimed different conditions; and

b) Lamps shall start and operate satisfactorily under claimed different conditions; and

c) Lamps shall meet the performance claims under the claimed different conditions, which may differ from the general conditions for measurement specified in A-1.
