General comments onthe Proposal for aDirective
Free circulation within thewhole Community isguaranted only forelectrical
apparatus fulfilling the provisions ofthe present Directive .
Thetechnical specifications with which electrical apparatus must comply are .
contained ,inharmonized standards which are identical totheEuropean
standards oftheEuropean Commit-tee forEject rotechnical Standardisation (CSUELEC )
except when amended bytheannexes oftheDirective .
Optional harmonization hasbeen adopted since itenables national standards
and harmonized standards tocoexist .

Thedetermination ofthose Darts referred toinArticle 3decends onlocal­

differences between these determinations donotconstitute abarrier totrade .
Article d(1)specifies that only safety against ignition offiredamp istobe
taken into account asthescope oftheharmonized standards ofconstruction is
limited tothis .The specifications ofcons' ;ruction which take into account

assuch standards are not harmonized .
For free circulation inMember States electrical apparatus must either conform
toharmonized standards (certificate ofconformity )ormust assure adegree of
safety atleast equivalent (inspection certificate ).

Proposal for a
COUNCIL DIRECTIVE
ontheapproximation ofthe laws oftheMember States concerning electrical
equipment foruse inpotentially explosive atmospheres inmines susceptible
tofire-damp
THE COUNCIL OFTHE EUROPEAN COMMUNITIES ,-
Having regard totheTreaty establishing theEuropean Economic Community ,and
inparticular Article 100thereof ;
Having regard totheproposal from theCommission ;
Having regard totheopinion oftheEuropean Parliament ;
Having regard totheopinion ofthe Economic and Social Committee ;
Whereas legislation inforce intheMember States toensure thesafety of
electrical equipment foruse inpotentially explosive atmospheres inmines
susceptible tofire-damp differs from oneMpmber State toanother ,andwhereas
these differences are such astoconstitute abarrier totrade ;
Whereas such differences may beeliminated byapproximating the laws oftheMember
States inorder toallow electrical equipment for use inpotentially explosive
atmospheres inmines susceptible tofire-damp andcomplying with harmonized
standards tobeput onthemarket throughout theCommunity ;
Whereas provision'should also bemade toallow electrical equipment using technical
processes different from those ofthese harmonized standards tobeput onthe
market ,provided such equipment ensures alevel ofsafety equivalent tothat of
equipment which conforms tothe harmonized standards ;
Whereas ,however ,compliance with harmonized standards orequivalence ofsafety
levels tothat ofequipment which conforms totheharmonized standards should
beexamined byabody approved bytheMember State concerned ;
t
Whereas apositive result ofsuch examination should beattested both bycertificates
and amark recognized inallMember States ;
Whereas ,inorder totake account oftechnical progress ,thetechnical specifications
prescribed intheharmonized standards onelectrical equipment foruse inpotentially
explosive atmospheres inmines susceptible tofire-damp need tobeadapted promptly ;
whereas ,tofacilitate theimplementation ofthemeasures necessary inthis connection ,
aprocedure should belaid down toensure close cooperation between theMember States
andtheCommission through theCommittee ontheadaptation totechnical progress of
the Directives ontheremoval oftechnical barriers tointra-Community trade in
electrical equipment inpotentially explosive atmospheres inmines susceptible tofire­
damp ;

ί -2- -
Whereas itispossible that electrical equipment foruse inpotentially
explosive atmospheres inmines susceptible tofire-damp ,although certified
andmarked forfree movement ,may represent asafety risk ;whereas a
procedure should therefore belaid down toobviate this risk ;
Whereas the mining legislation indifferent Member States applies also
tosurface installations ofmines susceptible tofire-damp ,andwhereas
itisnecessary toinclude inthis Directive electrical equipment foruse
insuch installations ;whereas itistherefore necessary toderogate from /
Council Directive 76/117/EECof18December 1975 onthe approximation of .
r
the laws oftheMember States concerning electrical equipment foruse in
1potentially explosive atmospheres andfrom Council Directive 79/196/EEC
of6February 1979 ontheapproximation ofthe laws oftheMember States
concerning electrical equipment foruse inpotentially explosive atmospheres
?employing certain types ofprotection ;

Article 1
Thi TsDirective shall apply toelectrical equipment foruse inunderground
parts ofmines susceptible tofire-damp which maybeendangered byfire-damp .
Byway .ofderogation from Directive 76/117/EEC,andfrom Directive 79/196/EEC
this Directive shall apply also toelectrical equipment foruse inthose
parts o"fsurface installations ofsuch mines which maybeendangered byfire­
damp from underground ventilation .
Article 2
Electrical equipment within themeaning ofthis Directive covers allitems
which ,intheir entirety orinpart ,useelectricity .
Article 3
Thedefinition ofunderground parts ofmines susceptible tofire-damp which
may beendangered byfire-damp andthe surface installations ofsuch mines
which may beendangered byfire-damp from underground ventilation isleft
tothe initiative ofthe Member States .
Article 4
1.Member States maynot,onsafety grounds inrespect oftheinflammability
offire-damp ,prohibit the sale orfree movement ortheuse for itsproper
purpose oftheelectrical equipment referred toinArticles 1and 2

certificate ofconformity issued under theconditions laid down
inArticle 8andbytheaffixing ofthemark provided for in
Article 11;
-ifitdiffers from harmonized standards because noprovision was ,
made insuch standards' for itsdesign andmanufacture ,butthe
examination hasestablished that itoffers adegree ofsafety at

Least equivalent tothat ofequipment which conforms tothe
harmonized standards andthis isattested byaninspection certificate
issued under the conditions laid down inArticle 9andbythe
affixing ofthemark provided forinArticle '11.
Forthepurposes ofthis Directive ,useforitsproper puroose means the
useofelectrical equipment inparts where fire-damp isliable toform
anexplosive mixture with air ,asprovided forintheharmonized ^
standards ofconstruction and asrecorded inthe certificate of \
conformity orinspection certificate .
Where they are not subject toother Community provisions ,installation
conditions andconditions ofuse'shall remain subject tothelaws,
