IEC 62776:2014 scope:

IEC 62776:2014 specifies the safety and interchangeability requirements, and the exchange operation together with the test methods and conditions required to show compliance of double-capped LED lamps with G5 and G13 caps, intended for replacing fluorescent lamps with the same caps, having:

- a rated power up to 125 W;

- a rated voltage up to 250 V.

Such LED lamps are designed for replacement without requiring any internal modification of the luminaire.

The existing luminaires, into which the double-capped LED lamps are fitted, can be operated with electromagnetic or electronic controlgear.

The requirements of this standard relate only to type testing.

General requirements and general test requirements:

a) The lamps shall be so designed and constructed that in normal use they function safely causing no danger to the user or surroundings.

b) Double-capped LED lamps shall normally not be opened for tests. In the case of doubt based on the inspection of the lamp and the examination of the lamp circuit diagram, and in agreement with the manufacturer or responsible vendor, lamps shall be specially prepared so that a fault condition can be simulated and shall be submitted for testing (see Clause 13). Opened lamps or inspection of internal component parts of the lamp may be required to verify conformity with Clause 11, 12 and 14 of this standard.

c) In general, all tests are carried out on each type of lamp or, where a range of similar lamps is involved, for each power in the range or on a representative selection from the range, as agreed with the manufacturer.

d) When the lamp fails safely during one of the tests, it is replaced, provided that no fire, smoke, or flammable gas is produced. Futher requirements on failing safe are given in Clause 13.

e) Internal wiring shall be carried out as in Clause 5.3 of IEC 60598-1.

f) For construction of the electrical circuit, 15.1 and 15.2 of IEC 61347-1 shall be regarded and for the other parts, Clause 4.11, 4.12 and 4.25 of IEC 60598-1 shall be regarded.
