GX16t-5 CAPPED TUBULAR LED LAMP –
SAFETY SPECIFICATIONS

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in
addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). 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. 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 IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses
arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62931 has been prepared by subcommittee 34A: Lamps, of IEC
technical committee 34: Lamps and related equipment.

4 General requirements and general test requirements
4.1 The lamps shall be so designed and constructed that in normal use they function safely
causing no danger to the user or surroundings.
In general, compliance is checked by carrying out all the tests specified.
4.2 GX16t-5 capped LED lamps shall normally not be opened for any tests. In the case of
doubt based on the inspection of the lamp and the examination of the circuit diagram, and in
agreement with the manufacturer or responsible vendor, either the output terminals shall be
short-circuited or, in agreement with the manufacturer, lamps specially prepared so that a fault
condition can be simulated shall be submitted for testing (see Clause 14). Opened lamps or
inspection of internal component parts of the lamp may be required to verify conformity with
Clauses 11, 12 and 13.
4.3 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.
4.4 When the lamp fails during one of the tests without any fire, smoke and flammable gas, it
is regarded as a safe failure and shall be replaced in the test. Further requirements on failing
safely are given in Clause 14.
4.5 Internal wiring shall be carried out according to the requirements in IEC 60598-1:2014,
5.3.
4.6 For the construction of the electrical circuit, the requirements in IEC 61347-1:2015, 15.1
and 15.2 shall be taken into account and for the construction of other parts, the requirements in
IEC 60598-1:2014, 4.11, 4.12 and 4.25 shall be taken into account.
NOTE Temperature conditions can be modified in the regional standards according to the climate there.
5 Marking
5.1 Marking on the lamp
Lamps shall be clearly and durably marked with the following marking:
a) mark of origin (this may take the form of a trademark, the manufacturer’s name or the name
of the responsible vendor);
b) lamp identification;
c) rated wattage (units: “W” or “watts”);
d) Information on the ingress of dust and water, see Figure 1:
– for lamps which do not comply with 16.3.

EC
IEC 60417-6179:2012-10
Figure 1 – Lamp not suitable for use under dust and moisture
5.2 Marking on the packing or in instructions
In addition, the following information shall be given by the lamp manufacturer on immediate lamp
wrapping (or container) or in instructions.
a) Mark of origin (this may take the form of a trademark, the manufacturer’s name or the name
of the responsible vendor);
b) Lamp identification;
c) rated wattage (units: “W” or “watts”);
d) Rated lamp current (units: “A” or “ampere”);
e) Nominal dimensions;
– unit: mm;
– example of marking: 1 200 mm × 26 mm.
f) Rated ambient temperature range of the lamp;
The ambient temperature range for which the lamp is rated shall be declared. Where the
minimum ambient temperature of the range is higher than –20 °C or the maximum ambient
temperature of the range lower than +60 °C the instruction manual for the lamp shall contain
the following information.
“This lamp may not be suitable for use in all applications where a traditional fluorescent lamp
has been used. The temperature range of this lamp is more restricted. In cases of doubt
regarding the suitability of the application the manufacturer of this lamp should be
consulted.”
NOTE 1 This document is based on the assumption that the normal expected ambient temperature range of the
fluorescent lamps that can be replaced by these retro-fit products is –20 °C to +60 °C.
g) Purpose of usage. Example of marking: “This lamp is designed for general lighting service
(excluding e.g. explosive atmospheres).”.
NOTE 2 The above mentioned information can also be marked on the lamp.
5.3 Durability and legibility of marking
Compliance with 5.1 and 5.2 is checked by the following:
Presence and legibility of the marking by visual inspection.
The durability of the marking – as far as applied on the lamp – is checked by trying to remove it
by rubbing lightly for 15 s with a piece of cloth soaked with water and, after drying, for a further
15 s with a piece of cloth soaked with hexane. The marking shall be legible after the test.
Availability of information required in 5.2 by visual inspection.

6 Interchangeability
6.1 Dimensional requirements of caps
Interchangeability shall be ensured by the use of GX16t-5 cap in accordance with IEC 60061-1
and gauges in accordance with IEC 60061-3. See Table 1.
Compliance is checked by the use of the relevant gauges.

6.2 Mass
The value of the lamp mass shall not exceed 500 g for a length up to and including 1,2 m and
1 000 g for a length above 1,2 m.
Compliance is checked by inspection using appropriate gauges (e.g. meter sticks and mass
balances).
6.3 Dimensions

For safe application to luminaires, dimensions of the lamp shall comply with the dimension
shown in the relevant lamp datasheet in Annex D over the rated ambient tem
