1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization

comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to

promote international cooperation on all questions concerning standardization in the electrical and

electronic fields. To this end and in addition to other activities, the IEC publishes International Standards.

Their preparation is entrusted to technical committees; any IEC National Committee interested in

the subject dealt with may participate in this preparatory work. International, governmental and

non-governmental organizations liaising with the IEC also participate in this preparation. The IEC

collaborates closely with the International Organization for Standardization (ISO) in accordance with

conditions determined by agreement between the two organizations.

2) The formal decisions or agreements of the IEC on technical matters, prepared by technical committees on

which all the Nationàl Committees having a special interest therein are represented, express, as nearly as

possible, an international consensus of opinion on the subjects dealt with.

3) They have the form of recommendations for international use published in the form of standards, technical

reports or guides and they are accepted by the National Committees in that sense.

4) In order to promote international unification, IEC National Committees undertake to apply IEC International

Standards transparently to the maximum extent possible in their national and regional standards. Any

divergence between the IEC Standard and the corresponding national or regional standard shall be clearly

indicated in the latter.

5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any

equipment declared to be in conformity with one of its standards.

International Standard IEC 155 has been prepared by sub-committee 34A: Lamps, of IEC

technical committee 34: Lamps and related equipment.

This fourth edition cancels and replaces the third edition published in 1983 and amend-

ments 1 and 2, and constitutes a technical revision.

The test of this standard is based on the third edition, on the amendments 1 and 2 and on

the following documents:
DIS Report on voting
34A(CO)635 34A(CO)686

Full information on the voting for the approval of this standard can be found in the report

on voting indicated in the above table.
This standard should be used in conjunction with IEC 81, IEC 901 and IEC 921.
Annexes A and B form an integral pa rt of this standard.

The additional requirements with which glow-starters for use in class II luminaires shall

comply are specified in annex B.

danger to the user or surroundings. In general, compliance is checked by carrying out all

the tests specified.
5 General requirements for tests
5.1 Requirements for type tests only are included.
Unless otherwise specified, the tests shall be made at an ambient temperature of
25 °C ± 5 °C.
The tests shall be carried out in the order of the clauses.

The sample to be tested is mounted vertically on the carriage and pressed against the

glow-wire tip with a force of 1 N, preferably 15 mm, or more, from the upper edge of

Any flame or glowing of the sample shall extinguish within 30 s of withdrawing the glow-

wire, and any burning or molten drop shall not ignite a piece of tissue paper, consisting of

five layers, spread out horizontally 200 mm ± 5 mm below the sample.

The glow-wire temperature and heating current shall be constant for 1 min prior to

commencing the test. Care shall be taken to ensure that heat radiation does not influence

the sample during this period. The glow-wire tip temperature is measured by means of a

sheathed fine-wire thermocouple constructed and calibrated as described in IEC 695-2-1.

Precautions shall be taken to safeguard the health of personnel conducting tests against:

- risks of explosion or fire;
inhalation of smoke and/or toxic products;
toxic residues.
7.11 Quality of marking

Compliance with the requirements shall be checked by inspection after rubbing the mark-

ing lightly for 15 s with a piece of cloth soaked with water.

The test shall be repeated using a further piece of cloth soaked with petroleum spirit.

Radio interference suppression capacitors

7.12.1 The starter shall incorporate a radio interference suppression capacitor value

between 0,005 .tF and 0,02 µF, unless otherwise indicated on the appropriate lamp data

sheet of IEC 81 or IEC 901. Compliance shall be checked by inspection.

7.12.2 The capacitor shall be resistant to moisture. Compliance shall be checked by the

following test.

Before the humidity treatment, the capacitors shall be kept at an ambient temperature

which does not differ from the temperature within the humidity test enclosure by more than

°C for at least 4 h.

Immediately after the humidity treatment of 24 h x 2 in an atmosphere of 91 % to 95

relative humidity and an ambient temperature between 20 °C and 30 °C maintained within

°C, the capacitor shall be subjected to and satisfactorily withstand for 1 min
limits of
without breakdown a d.c. voltage of 2 000 V.

The test voltage shall be applied across the terminations of the capacitor, and initially

shall not be more than half the prescribed voltage. It shall then be raised gradually to the

specified full value.
The capacitor shall be resistant to flame and ignition.

Compliance shall be checked by the following test. The capacitors are each subjected to a

gradually increasing a.c. voltage until breakdown occurs. The voltage source used to this

effect should have a short-circuit power of approximately 1 kVA.
