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.

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.
---------------------- Page: 10 ----------------------
IEC 62931:2017 © IEC 2017 – 9 –
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.

GX16t-5 7004-183 All dimensions to be checked 7006-183 and 7006-183A
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
6.3.1 General

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
