Miniature lamps
1 General
1.1 Scope
This standard specifies the requirements for small halogen and non-halogen lamps,
which have a rated voltage not greater than 30 V and a rated power not greater than 25
W. It includes:
- Lamps for use on road motor vehicles that are not covered by the regulations and
are therefore not included in IEC 60809 (Chapter 2);
- Torch (Chapter 3);
- Mining caplights (Chapter 4).
For requirements on aircraft lamps, see GB/T 21095.
This standard specifies the requirements for size, optoelectronic performances, as well
as life and mechanical strength.
Note: These requirements are for product lamps. Individual lamps may not fall entirely within
these requirements, which requires consistency conditions, which are specified in the
corresponding chapter.
For some requirements specified in this standard, refer to the "Relevant Lamp Data
Sheet". For some lamps, data sheets are included in this standard. For other lamps
falling within the scope of this standard, relevant data are provided by the lamp
manufacturer or responsible seller.
This standard may also be used for the development of future light sources, for example,
light sources emitting light from light-emitting diodes (LEDs).
1.2 Normative references
The provisions in following documents become the provisions of this Standard through
reference in this Standard. For the dated references, the subsequent amendments
(excluding corrections) or revisions do not apply to this Standard; however, parties who
reach an agreement based on this Standard are encouraged to study if the latest versions
of these documents are applicable. For undated references, the latest edition of the
- The second set of numbers consists of four digits. The first digit indicates the
corresponding chapter of this standard. The second and third digits indicate the data
sheet identification number. The fourth digit, except zero, indicates the lamp type.
The number zero is used as a part of an identification number of data sheet;
- The third set of numbers represents the edition number of the data sheet. When the
data sheet has more than one page, each page may have a different edition number;
but the data sheet number remains the same.
1.7 Recommended guidelines for the use of halogen lamps
If tungsten halogen lamps covered by this standard are provided, it is recommended
that the following points be included in any instructions for use:
- The temperature of the glass lamp of the tungsten halogen lamp is high, when it is
working. Care shall be taken to avoid touching the glass shell under any
circumstances;
- If the glass shell of a quartz glass lamp has been touched, it shall be wiped clean
with a soft, lint-free cloth soaked in ethanol before use;
- Lamp shells with scratches or other damages cannot be used.
Note: In some cases, the lamp manufacturer provides information on the pressure gas within
the lamp and recommends protective measures.
2 Auxiliary lamps for road vehicles
2.1 Scope
This chapter deals with miniature lamps, which are used on road motor vehicles that
are not covered by regulations and are therefore not included in IEC 60809. It specifies
basic requirements (dimensions, photoelectric properties) as well as requirements for
life and torsional strength performance.
2.2 Definition
For the purposes of this Chapter, in addition to the definitions in Chapter 1, the
following definitions apply.
2.2.1
Designation
EUR: A type that has been standardized in European countries.
JIS: A type standardized by Japanese Industrial Standards.
SAE: A type standardized by the Society of Automotive Engineers (USA).
2.3 Signs
The following shall be clearly and durably printed on the lamp:
- The trade name or trademark of the manufacturer or responsible seller;
- Trade designation or lamp designation and/or nominal voltage.
Additionally, other content can be printed, such as nominal wattage.
Compliance is checked by rubbing the lamp with a smooth cloth, which was soaked in
water for 15 seconds.
After this test, the sign shall be clear.
2.4 Technical requirements and test procedures
Lamps shall comply with the general requirements given in 1.5.
2.4.1 Initial reading
After aging, the power and luminous flux of the lamp under the test voltage shall
comply with the requirements, which are specified in the corresponding data sheet. An
appropriate integrating photometer shall be used, when measuring the luminous flux.
2.4.2 Life
During the life test, the lamp shall operate under DC or AC voltage, which has a
frequency between 40 Hz and 60 Hz. The reference axis and filament axis are in a
horizontal position; the room temperature does not exceed 30 °C.
There must be no fluctuations in the supply voltage. However, instantaneous
fluctuations not exceeding ±1% of the test voltage (≤1 min) are allowed.
The life test shall end at 150% of the life value specified in the corresponding lamp data
sheet. The lamp that terminates the test at this time shall be deemed to have a life of
150% of the specified value.
The average life of the test sample shall not be less than:
3.4.1 Initial reading
After aging, the current and luminous flux of the lamp under the test voltage shall
comply with the requirements, which are specified in the corresponding data sheet. An
appropriate integrating photometer shall be used to measure the luminous flux.
3.4.2 Life
During the life test, the lamp shall be placed horizontally, operating under DC or AC
test voltage at a frequency between 40 Hz and 60 Hz; the room temperature shall not
exceed 30 °C.
There shall be no fluctuations in the power supply voltage. However, instantaneous
fluctuations not exceeding ±1% of the test voltage (≤1 min) are allowed.
The average life of the test sample shall not be less than the rated life value, which is
specified in the corresponding lamp data sheet.
