INTERPRETATION SHEET 1



This interpretation sheet has been prepared by subcommittee 34A: Lamps, of IEC technical
committee 34: Lamps and related equipment.
The text of this interpretation sheet is based on the following documents:
FDIS Report on voting
34A/2081/FDIS 34A/2090/RVD

Full information on the voting for the approval of this interpretation sheet can be found in the
report on voting indicated in the above table.

___________

Interpretation of Clause 7 of IEC 62776:2014
The statement in the first paragraph of Clause 7 that “there shall not be any electrical
continuity between the two ends of the lamp during the insertion” is in contradiction with the
compliance requirements that follow. In the physical world, establishing the complete lack of
any electrical continuity between the two ends is not possible since all materials may be
characterized by their inherent conductivity however small it may be.
The compliance requirements described in the fourth paragraph of Clause 7 shall take
precedence.

DOUBLE-CAPPED LED LAMPS DESIGNED

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.

INTRODUCTION
Double-capped fluorescent lamps are installed in big volume in office lighting, street lighting,
industrial lighting and much more. Double-capped LED lamps are intended as a possible
replacement for G5- or G13-capped fluorescent lamps. This standard safeguards that the
change from fluorescent lamp to LED lamp and the backward change from LED lamp to
fluorescent lamp is carried out with safe LED lamps and under specified exchange conditions.
The establishing of a safety standard for double-capped LED lamps does not exclude future
relocation as a part of IEC 60968, self-ballasted lamps (if re-edited as an umbrella standard),
and further inclusion of requirements for conversion type double-capped LED lamps.
This proposal covers double-capped LED lamps with cap G5 and G13 only, where the
fluorescent tube is replaced by a tubular LED lamp, without modifications to the luminaire.
Only in case of electromagnetic controlgear, the starter is replaced by a LED starter.

DOUBLE-CAPPED LED LAMPS DESIGNED
TO RETROFIT LINEAR FLUORESCENT LAMPS –
SAFETY SPECIFICATIONS



1 Scope
This International Standard specifies the safety and interchangeability requirements, and the
exchange operation together with the test methods and conditions required to show
compliance of double-capped LED lamps with G5 and G13 caps, intended for replacing
fluorescent lamps with the same caps, having:
– a rated power up to 125 W;
– a rated voltage of up to 250 V.
Such LED lamps are designed for replacement without requiring any internal modification of
the luminaire.
The existing luminaires, into which the double-capped LED lamps are fitted, can be operated
with electromagnetic or electronic controlgear.
The requirements of this standard relate only to type testing.
Recommendations for whole product testing or batch testing are given in Annex A.
NOTE 1 Where in this standard the term “lamp(s)” is used, it is understood to stand for “double-capped retrofit
LED lamp(s)”, except where it is obviously assigned to other types of lamps.
This standard does not cover double-capped conversion LED lamps where modification in the
luminaire is required. The requirements in this standard are given for general lighting service
(excluding for example explosive atmospheres). For lamps for other applications additional
requirements may apply.
NOTE 2 This standard includes photobiological safety.
