4 Requirements and test conditions for filament lamps
4.1 General requirements
Filament lamps shall be so designed as to be and to remain in good working order when in normal use. They shall, moreover, exhibit no fault in design or manufacture.
4.2 Lamp marking
The following information shall be legibly and durably marked on all filament lamps, except for
non-replaceable filament lamps:
— the trade name or mark of the manufacturer or responsible vendor;
— the nominal voltage;
— the international designation of the relevant category;
— the nominal wattage (in the sequence: high wattage filament/low wattage filament for dual filament lamps); this need not be indicated separately if it is part of the international designation of the relevant filament lamp category.
Additionally, halogen filament lamps meeting the requirements of 4.9 shall be marked with a “U”.
NOTE 1 Halogen filament lamps are filament lamps whose category designation usually starts with the letter “H. Some halogen lamps complying with the requirements in 4.9 have a category designation starting with another letter.
Inscriptions other than the above may be affixed.
NOTE 2 An example of such an inscription is the approval mark or the approval code conferred by an administrative authority.
Compliance shall be checked by the following:
a) presence and legibility — by visual inspection;
b) durability — by applying the following test on unused lamps:
The area of the marking on the lamp shall be rubbed by hand with a smooth cloth, dampened with water, for a period of 15 s.
After this test the marking shall still be legible.
It shall be verified that if the marking is on the bulb, it does not affect the luminous characteristics as specified on the light source data sheet.
4.3 Bulbs
Filament lamp bulbs shall exhibit no scores or spots which might impair their optical performance. In case of doubt the visual inspection shall be carried out.
4.6 Caps and bases
Filament lamps shall have standard caps or bases as specified on the relevant filament lamp data sheet and shall comply with the relevant cap data sheet of IEC 60061-1. This requirement does not apply to non-replaceable filament lamps; in this case, filament lamps shall be equipped with bases that allow firm and secure fixation to the lighting or light signalling devices, or to parts/modules/units of such devices, for which these filament lamps are designed and intended.
4.7 Initial electrical and luminous requirements
Filament lamp wattage and luminous flux shall comply with the limiting values given on the relevant lamp data sheet.
The luminous flux specified on the relevant filament lamp data sheet applies for filament lamps emitting white light, unless a special colour is stated on the data sheet.
In the case where selective-yellow colour is allowed, the luminous flux of the filament lamp with selective-yellow (outer) bulb shall be at least 85 % of the specified luminous flux of the relevant filament lamps with a colourless bulb.
Compliance shall be checked by the tests specified in Annex C, Clause C.1.
4.8 Check on optical quality
4.8.1 General
This requirement applies only to double filament lamps with internal shield for headlamps emitting an asymmetrical dipped beam when the relevant regulation requires such a test.
The check on optical quality shall be carried out at a voltage such that the test luminous flux is obtained.
4.8.2 12 V lamps emitting white light
The sample which most nearly conforms to the requirements laid down for the standard filament lamp shall be tested in an appropriate standard headlamp and it shall be verified that the assembly comprising the aforesaid headlamp and the filament lamp being tested meets the light-distribution requirements laid down for the dipped beam in the relevant regulation, directive or standard.
4.8.3 6 V and 24 V lamps emitting white light
The sample which most nearly conforms to the rated dimension values shall be tested in an appropriate standard headlamp and it shall be verified that the assembly comprising the aforesaid headlamp and the filament lamp being tested meets the light-distribution requirements laid down for the dipped beam in the relevant regulation, directive or standard. Deviations not exceeding 10 % of the minimum values will be acceptable.IEC 60809 pdf download.
