COUNCIL DIRECTIVE
of 15February 1982
on the approximation of the laws of the Member States concerning
electrical equipment for use in potentially explosive atmospheres in
mines susceptible to firedamp
(82/130/EEC)
THE COUNCIL OF THE EUROPEAN COMMUNITIES,
Having regard to the Treaty establishing the European Economic
Community, and in particular Article 100 thereof,
Having regard to the proposal from the Commission(1),
Having regard to the opinion of the European Parliament(2),
Having regard to the opinion of the Economic and Social Committee(3),
Whereas legislation in force in the Member States to ensure the safety
of electrical equipment for use in potentially explosive atmospheres inmines susceptible to firedamp differs from one Member State toanother; whereas these differences are such as to constitute a barrier totrade;
Whereas such differences may be eliminated by approximating the laws
of the Member States in order to allow electrical equipment complyingwith harmonized standards for use in potentially explosive atmospheresin mines susceptible to firedamp to be put on the market throughout theCommunity;
Whereas provision should also be made to allow electrical equipment
using technical processes different from those of these harmonizedstandards to be put on the market, provided such equipment ensures alevel of safety equivalent to that of equipment which conforms to theharmonized standards;
Whereas, however, compliance with harmonized standards or equiva-
lence of safety levels to that of equipment which conforms to theharmonized standards should be verified and tested by a body approvedby the Member State concerned;
Whereas a positive result of such verifications and tests should be
confirmed both by a certificate and the mark recognized in all MemberStates;
Whereas, in order to take account of technical progress, the technical
requirements prescribed in the harmonized standards on electricalequipment for use in potentially explosive atmospheres in minessusceptible tofiredamp need tobe adapted pro mptly; whereas, tofacili-tate the implementation of the measures necessary in this connection, aprocedure should be laid down to ensure close cooperation between theMember States and the Commission through the Committee on theadaptation to technical progress of the Directives on the removal oftechnical barriers tointra-Co mmunity trade in electrical equipment inpotentially explosive atmospheres in mines susceptible to firedamp;
Whereas it is possible that electrical equipment for use in potentially
explosive atmospheres in mines susceptible to firedamp, although certi-fied and marked for free movement, may represent a safety risk;whereas a procedure should therefore be laid down to obviate this risk;
Whereas the mining legislation in different Member States applies also
to surface installations of mines susceptible to firedamp; whereas it isnecessary toinclude in this Directive electrical equipment fo r use insuch installations; whereas it is therefore necessary to derogate fromCouncil Directive 76/117/EEC of 18 December 1975 on the approx-
(1) OJ NoC 104, 28. 4. 1980, p. 92.

comply with the requirements for electrical apparatus of category ‘ib'(see 4.2 ofEuropean Standard EN 50 020 ‘Intrinsic safety') except that the intrinsicallysafe electrical system as a whole shall be considered as a single item of electricalapparatus.
4.Interconnecting wiring in an intrinsically safe electrical system
4.1. The electrical parameters and all characteristics of the interconnecting
wiring specific toan intrinsically safe electrical system, in sofar as intrinsicsafety depends on them, shall be specified in the certification documents for thatelectrical system.
4.2. Where a multicore cable contains interconnections which are parts of more
than one intrinsically safe circuit the cable shall meet the following requirements:
4.2.1. The radial thickness of the insulation shall be appropriate to the diameter
of the conductor. In the case of polyethylene, the minimum radial thickness shallbe 0.2 mm.
4.2.2. Before leaving the manufacturer’s works, the multicore cable shall be
submitted toAC dielectric tests specified either in 4.2.2.1 o r in 4.2.2.2. Thesuccess of these tests shall be attested by a tests certificate issued by the cablemanufacturer.
4.2.2.1. Either each core, before assembly into the cable, is tested at a voltage
value (rms) equal to3 00 0V+( 2 0 0 0 times the radial thickness of the insula-
tion in mm) V; the assembled cable:
— is firstly tested at a voltage value (rms) equal to 500 V applied between all
the armourings or screens of the cable joined together electrically and thebundle of all cores joined together electrically and
— is secondly tested at a voltage value (rms) equal to 1 000 V applied between
a bundle comprising one half of the cable cores and a bundle comprising theother half of the cores.
4.2.2.2. Or the assembled cable:
— is firstly tested at a voltage value (rms) equal to 1 000 V applied between all
the armourings or screens of the cable joined together electrically and thebundle of all cores joined together electrically and
— is secondly tested at a voltage value (rms) equal to 2 000 V applied in
succession between each core of the cable and the bundle formed by all theother cores joined together electrically.
4.2.3. The tests prescribed in 4.2.2 shall be carried out with an a.c. voltage of
substantially sinusoidal wave form at a frequency between 48 Hz and 62 Hzgiven by a transformer of appropriate power, taking into account the cablecapacity. In the case of dielectric tests on assembled cables, the voltage shall beincreased steadily to the specified value in a period not less than 10 seconds andthen maintained for at least 60 seconds.
These tests are carried out by the cable manufacturer.4.3. No fault between the cores of a multicore cable shall be taken into account
if one of the two following requirements are satisfied:
4.3.1. The cable conforms to 4.2 and each individual intrinsically safe circuit is
enclosed in a conducting screen providing at least 60 % coverage.
Note:The eventual connection of the screen to earth or frame will be specified
in the installation rules.
4.3.2. The cable conforms to 4.2, is effectively protected against damage and
each intrinsically safe circuit within the cable has, in normal operation, a peakvoltage of equal to or less than 60 volts.

trical system, faults shall be considered between up to 4 cores of the cable in
addition to the application of either 3.2 or 3.3.
4.5. Where a multicore cable conforms with 4.2 but not with 4.3 and contains
intrinsically safe circuits forming parts of different intrinsically safe electricalsystems, each intrinsically safe circuit contained in the cable shall have a safetyfactor of at least four times that required by either 3.2 or 3.3.
4.6. Where a multicore cable does not comply with 4.2 and 4.3, any number of
faults between the cores of the cable shall be taken into account in addition to theapplication of 3.2 or 3.3.
4.7. The certification documents of the intrinsically safe electrical system shall
specify the conditions of use resulting from the application of 4.3 to 4.6.
5.Accessories used in intrinsically safe electrical systems

GENERAL REQUIREMENTS
(European standard EN 50014)
Replace the text of 7.3.1 of European Standard EN 50014 (December 1992) by
the following text:
‘7.3.1. Electrical apparatus of Group IEnclosures of plastic materials with a surface area projected in any direction
of more than 100 cm
2, or containing exposed metallic parts with a capacitance
to earth of more than 3 pF, under the most unfavourable conditions inpractice, shall be so designed that under normal conditions of use, mainte-nance and cleaning, danger of ignition due to electrostatic charges is avoided.
This requirement shall be satisfied:
— either by suitable selection of the material: its insulation resistence, meas-
ured according to the method given in 23.4.7.8 of this European standard,shall not exceed:
—1G Ωat 23 ± 2 °Ca n d5 0±5% relative humidity,
— 100 G Ωunder extreme service conditions of temperature and
humidity specified for the elctrical apparatus; the X shall then beplaced after the certificate reference, as indicated in, 27.2.9,
— or by the size, shape, layout or by other protective methods. The non
appearance of dangerous electrostatic charges shall then be verified byactual tests for ignition of an air methane mixture containing 8,5 ± 0,5 %of methane.
If, however, the danger of ignition cannot be avoided in the design, a warning
label shall indicate the safety measures tobe applied in service'.

ELECTRICAL APPARATUS FOR POTENTIALLY EXPLOSIVE
ATMOSPHERES OF GROUP I
INTRINSIC SAFETY ‘i'
Intrinsically safe electrical systems
Note:In mines susceptible tofiredamp in the Federal Republic o f Germany, the
word ‘Anlage' is used instead of ‘System'.
1.Scope
1.1. This Annex contains the specific requirements for construction and
testing of intrinsically safe electrical systems all or parts of which areintended for installation in potentially explosive atmospheres of minessusceptible tofiredamp, in o rder toensure that such electrical systemswill not cause an explosion in the surrounding atmosphere.
1.2. This Annex supplements European Standard EN 50020‘Intrinsic safety
“i”' (second edition, August 1994) the requirements of which apply tothe construction and testing of intrinsically safe electrical apparatus andassociated electrical apparatus.
1.3. This Annex does not take the place of installation rules for intrinsically
safe electrical apparatus, associated electrical apparatus and intrinsicallysafe electrical systems.
2.Definitions
2.1. The following definitions, specific to intrinsically safe electrical
systems, are applicable in this Annex. They supplement the definitionswhich are in European Standards EN 50 014‘General requirements'andEN 50020‘Intrinsic safety “I”'.
2.2. Intrinsically safe electrical system
An assembly of items of electrical apparatus defined in a descriptive
system document in which the interconnecting circuits, or parts of suchcircuits, intended for use in a potentially explosive atmosphere, areintrinsically safe circuits, and which meet the requirements of thisAnnex.
2.3. Cerified intrinsically safe electrical system
An electrical system conforming to 2.2 for which a testing station has
issued a system certificate, certifying that the type of electrical systemcomplies with this Annex.
Note 1:It is not necessary for each electrical apparatus in an intrinsi-
cally safe electrical system tobe certified individually, but itmust suitably be identifiable.
Note 2:In so far as the national regulations for installation make it
possible, electrical systems conforming to 2.2, for which theknowledge of the electrical parameters of the items of certifiedintrinsically safe electrical apparatus, certified associated elec-trical apparatus, non-certified devices conforming to 1.3 ofEuropean Standard EN 50014‘General requirements', and theknowledge of the electrical and physical parameters of thecomponents and interconnecting wiring permits the unambig-uous deduction that intrinsic safety is conserved, can beinstalled without additional certificates.
2.4. Accessory
Electrical apparatus which contains only components for connecting and
switching intrinsically safe circuits and which dono t prejudice theintrinsic safety of the system, such as terminal boxes, junction boxes,plugs and sockets and similar items, switches, etc.
3.Categories of intrinsically safe electrical systems
3.1. Intrinsically safe electrical systems, or parts thereof, shall be placed in
one of the two categories: ‘ia' or ‘ib'. The requirements of this Annexapply to both categories, unless otherwise specified.
Note:Intrinsically safe electrical systems, or parts thereof, may have
categories different from those of the intrinsically safe electricalapparatus and associated electrical apparatus included in the
1982L0130 — EN — 09.10.1998 — 002.001 — 15

system or part thereof. Also different parts of an intrinsically safe
electrical system may have different categories.
3.2. Category ‘ia'
Intrinsically safe electrical systems, or parts thereof are of category ia if
they comply with the requirements for intrinsically safe electrical appa-ratus of category ‘ia'(see 5.2 of European Standard EN 50020‘Intrinsicsafety'), except that the intrinsically safe electrical system as a wholeshall be considered as a single item of electrical apparatus.
3.3. Category ‘ib'
Intrinsically safe electrical systems, or parts thereof, are of category ib if
they comply with the requirements for electrical apparatus of category‘ib' (see 5.3 of European Standard EN 50020‘Intrinsic safety') exceptthat the intrinsically safe electrical system as a whole shall be consid-ered as a single item of electrical apparatus.
4.Interconnecting wiring in an intrinsically safe electrical system
4.1. The electrical parameters and all characteristics of the interconnecting
wiring specific toan intrinsically safe electrical system, in sofar asintrinsic safety depends on them, shall be specified in the certificationdocuments for that electrical system.
4.2. Where a multicore cable contains interconnections which are parts of
more than one intrinsically safe circuit the cable shall meet thefollowing requirements:
4.2.1. The radial thickness of the insulation shall be appropriate to the diam-
eter of the conductor. In the case of polyethylene, the minimum radialthickness shall be 0,2 mm.
4.2.2. Before leaving the manufacturer’s works, the multicore cable shall be
submitted toAC dielectric tests specified either in 4.2.2.1 o r in 4.2.2.2.The success of these tests shall be attested by a tests certificate issued bythe cable manufacturer.
4.2.2.1. Either each core, before assembly into the cable, is tested at a voltage
value (rms) equal to3 000 V + (2 000 times the radial thickness o f theinsulation in mm) V; the assembled cable:
— is firstly tested at a voltage value (rms) equal to 500 V applied
between all the armourings or screens of the cable joined togetherelectrically and the bundle of all cores joined together electrically,and
— is secondly tested at a voltage value (rms) equal to 1 000 V applied
between a bundle comprising one half of the cable cores and abundle comprising the other half of the cores.
4.2.2.2. Or the assembled cable:
— is firstly tested at a voltage value (rms) equal to 1 000 V applied
between all the armourings or screens of the cable joined togetherelectrically and the bundle of all cores joined together electrically,and
— is secondly tested at a voltage value (rms) equal to 2 000 V applied
in succession between each core of the cable and the bundle formedby all the other cores joined together electrically.
4.2.3. The tests prescribed in 4.2.2 shall be carried out with an a.c. voltage of
substantially sinusoidal wave form at a frequency between 48 and 62 Hzgiven by a transformer of appropriate power, taking into account thecable capacity. In the case of dielectric tests on assembled cables, thevoltage shall be increased steadly to the specified value in a period notless than 10 seconds and then maintained for at least 60 seconds.
These tests are carried out by the cable manufacturer.
4.3. No fault between the cores of a multicore cable shall be taken into
account if one of the two following requirements is satisfied:
4.3.1. The cable conforms to 4.2 and each individual intrinsically safe circuit is
enclosed in a conducting screen providing at least 60 % coverage.
Note:The eventual connection of the screen to earth or frame will be
specified in the installation rules.
