ISO 2678, Environmental tests for aircraft equipment — Insulation resistance and high voltage tests for electrical equipment ISO 7137, Aircraft — Environmental conditions and test procedures for airborne equipment IEC 60061-3, Lamp caps and holders together with gauges for the control of interchangeability and safety —Part 3: Gauges 3 Tests 3.1 Test conditions Unless otherwise specified, the tests shall be carried out under the following conditions:  ambient temperature: 15 °C to 35 °C;  atmospheric pressure: 84 kPa to 107 kPa;  relative humidity < 85 %. Prior to all tests, the lamps shall be placed in these conditions for 1 h. The atmosphere of the environment shall not undergo any significant variations during a series of tests. (See ISO 7137.) NOTE Each lamp subjected to tests shall be the object of individual monitoring. 3.2 Visual examination 3.2.1 External appearance The lamps shall not present any defect capable of having an adverse effect on their installation or correct functioning; they shall conform with the characteristics specified in the product standards. The bulb shall have a regular shape and shall not exhibit any defect which may adversely affect utilization. The form and position of the filament shall conform with the indications given in EN 2240-002. SIST EN 2756:2010

3.4.2 Homogeneity of filament When the lamp is energized at 50 % of nominal voltage, the filament shall appear homogenous and exhibit a uniform brightness except in the vicinity of points of contact with the support(s) and at the leadwires, where account shall be taken of the cooling effect. 3.4.3 Luminous flux at nominal voltage The lamp shall be placed in a correctly calibrated integrating photometer (e.g.: Ulbricht sphere) where it is supplied with direct current at stabilized nominal voltage; the tolerance under test voltage shall be fixed at:  ± 0,1 % for a test voltage > 6 V;  ± 0,2 % for a test voltage ≤ 6 V. When thermal equilibrium has been reached, the intensity of the electric current and the luminous flux are measured. The power consumed shall be equal to the nominal value to within ± 10 %.
The luminous flux recorded shall be equal to the nominal values specified in the product standards, taking account of the tolerances (± 25 %, ± 15 %, ± 10 %) appropriate to the category of lamp. 3.4.4 Luminous flux at reduced voltage This test concerns the lamps for use at reduced voltage. The lamp shall first be subjected to tests specified in 3.4.3. The lamp shall then be energized with direct current at reduced stabilized voltage as specified in the product standard applying the same tolerance as under 3.4.3. SIST EN 2756:2010
