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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 62013-1 has been prepared by IEC technical committee 31:
Equipment for explosive atmospheres.
This second edition cancels and replaces the first edition (1999) and constitutes a technical
revision.
The general revision and updating of Edition 1 is a result of feedback from the manufacturers
and the certifiers following the use of the standard. Its purpose is clarification and the
elimination of any ambiguities. Account has also been taken of changes in related standards.

Part 1: General requirements –
Construction and testing in relation to the risk of explosion



1 Scope
This part of IEC 62013 specifies requirements for the construction and testing of caplights,
including caplights with a point of connection for another apparatus, for use in mines
susceptible to firedamp (Group I – electrical apparatus for explosive gas atmospheres as
defined in IEC 60079-0). It deals only with the risk of the caplight becoming a source of
ignition.
1
NOTE 1 The requirements for performance are in IEC 62013-2 .
The requirements of IEC 60079-0 do not apply unless specified.
This standard is also applicable to caplights intended for use in mines which have become
temporarily endangered by an explosive gas atmosphere, for example in mine rescue
operations.
NOTE 2 The use in such circumstances is dependent on a user’s risk assessment.
Caplights complying with this standard are intended for personal use under normal conditions
of:
o o
Temperature: 0 C to +40 C
Pressure: 0,8 bar to 1,1 bar
NOTE 3 In designing apparatus for operation in conditions other than those given above, this standard may be
used as a guide; however, additional testing may be required.

4.5 Surface temperature
The limitation of maximum surface temperature shall be in accordance with 5.3.2.1 of
IEC 60079-0.
4.6 Supply of electrical power to another apparatus
Where the caplight is also used to supply electrical power to another apparatus (internal or
external to the caplight) the other apparatus shall not affect compliance with this standard.
4.7 Creepage and clearance distances
All wiring connections and printed wiring boards which can affect the type of protection
afforded shall be considered to have infallible separations if they meet the following creepage
and clearance requirements:
– 1,6 mm in air up to 24 V, thereafter Table 1 of IEC 60079-7 applies;
– 0,5 mm through solid insulation or under a coating;
4.8 Assembled electrical connection
It shall not be possible to obtain a current of greater than 50 mA between any two accessible
points of the caplight when assembled for use.
5 Overcurrent protection
5.1 Overcurrent protection shall be provided which effectively limits the discharge current to a
level unlikely to cause an ignition of an atmosphere endangered by firedamp. Such protection
shall be provided by one or more of the following means:
a) a fuse or thermal circuit-breaker meeting the requirements of 5.2;
b) selecting a battery with appropriate internal characteristics meeting the requirements of 5.3;
c) an infallible current limiting resistor meeting the requirements of 5.3 and 5.4;
d) an active current limiting device meeting the requirements of 5.3 and 5.5.
If the battery-charging current passes through the protective means, the rating of that means
shall be based on the charge current or caplight working current, whichever is the greater.
5.2 Where the means of overcurrent protection is a fuse or thermal circuit-breaker and the
caplight is constructed in such a manner that
– the nominal voltage is not greater than 6 V;
– the value of the current in normal use is not greater than 1,5 A, and
– the nominal rating of the lamp is not greater than 6 W

---------------------- Page: 13 ----------------------

62013-1  IEC:2005 – 17 –
the fuse or thermal circuit-breaker shall conform to the following requirements:
a) a fuse or thermal circuit-breaker not housed in an enclosure meeting the requirements of
IEC 60079-1 shall be protected so that, when tested according to 10.5, there is no ignition
of any surrounding gas mixture,
NOTE An example of such suitable protection is to cover, except for the terminations, with an appropriate
3
encapsulation compound (see 4.21 of IEC 60455-1 ) with a minimum thickness of 1 mm.
and
b) the fuse shall comply with IEC 60127-2 and additionally meet the following criteria.
The fusing or interrupting current and fusing or interrupting time shall be as small as possible
with regard to the current/time charging and discharging characteristics of the battery. The
following rules shall apply:
– fusing or interrupting time at 12 A ± 0,1 A: not more than 1 s, and
– fusing or interrupting time at 15 A ± 0,1 A: not more than 200 ms.
5.3 In the case of 5.1b), c), or d) the combination of the battery and the means of protection
shall conform to the requirements of IEC 60079-11 using the spark ignition test described in
10.10. During the spark ignition test where a fuse is provided, it shall be replaced by an
equivalent resistance of suitable rating to allow the test to be performed.
Alternatively, the spark ignition test of intrinsic safety circuits in fault conditions may be carried
out in accordance with Clause A.2 of IEC 60079-11.
5.4 In the case of 5.1c) where the means of overcurrent protection is a resistor or resistors, it
shall be connected into the circuit as near to the battery terminals as possible. The resistor(s)
shall be of the metal or metal oxide film type, or of the single layer wire-wound type with
mechanical protection to prevent unwinding of the wire in the event of breakage, or any similar
construction, which has a failure mode that increases resistance. The resistors shall
a) be operated at no more than 2/3 of the power rating and meet the requirements of
IEC 60079-11 for an infallible current-limiting resistor, or
o
C, or decrease in resistance by more than 10 % of its pre-test value or
b) not exceed 450
flame or deform such that an adjacent conductor could short circuit the resistor when
subjected to current limiting resistor tests in 10.12. The temperature shall not adversely
affect the type of protection.
5.5 In the case of 5.1d) when the overcurrent protection is made by active current-limiting
devices, two devices in accordance with 7.1 of IEC 60079-11 in series shall be used. This does
not preclude the use of one active device and a fuse complying with 5.2, in series.
5.6 The physical arrangement of the means of overcurrent protection and the cable within the
battery container shall be such that a short-circuit current not passing through the means of
protection is unlikely.
