PROPOSAL FORACOUNCILDIRECTIVE
ontheapproximation ofthelawsoftheMemberStages
relatingto

EXPLANATORY MEMORANDUM
I,GENERAL
This Directive results from theapplication ofArticle 100ofthe
Treaty inconnection with theCouncil Directive of26July 1971 on
theapproximation ofthelaws oftheMember States relating tocommon
provisions forboth measuring instruments and methods ofmetrological
control (1).
Itisaimed atremoving technical barriers totrade within theCom­
munity which exist atpresent in'theTaximeter sector asaresult of
divergences inthenational laws governing these instruments inthe
Member States .
Acomparative examination oftherules applying toTaximeters showed
that thedifferences are not restricted solely tothetechnical re­
quirements applying toconstruction ,materials ,indicator devices and
markings ,but extend also toaccuracy and themethods ofmetrological
control towhich these instruments are subjected before they are
placed onthemarket and employed .
Asimilar situation isreflected atthetrading level in -themanda­
tory requirement formanufacturers tovary their production inorder
totake account of -the .regulations inforce intheMember State where
these instruments areintended tobeused and toundergo repeated
checks along various lines .
Since thepresent national laws are justified bythelegitimate desire
,toprotect consumers ,harmonization ofthese laws appears theonly
means likely toremove thedrawbacks arising from their diversity and
tocreate theconditions necessary forestablishing the corrmon market .
(1)GJNoL202of6September 1971 *)

TheCouncil and theCommission have long regarded itasessential to
undertake harmonization inthis sector ,andasalready contemplated in
the "General Programme "aimed atremoving technical barriers totrade "
adopted on28May1969 *andinthe "Resolution onIndustrial Policy "
which itadopted on17December 1973 *,|,»theCouncil hasinvited the
Commission toforward toitaproposal for aDirective onTaximeters
before 1January 1976 ,with aview toitsadoption bytheCouncil
before 1January ^977•Thetext inquestion isappended .
TheComumnity used theRecommendation recently adopted bytheInterna­
tional Organization ofLegal Metrology asthebasis forthis Directive ,
thus ensuring that therequirements featuring initarebased ona
consensus gained over amuch wider field than that oftheCommunity
alone .
The legally operative part appears inastraightforward form asis
customary forDirectives onMeasuring Instruments .
Article 1defines thescope oftheDirective .
Article 2lays down which Taximeters may begranted EECmarks and
symbols andtheconditions under which they shall besubmitted topat­
tern approval and initial verification .
Inview ofthewide variety oftariff regulations inforce intheMem­
ber States andalso the fact that final adjustment oftheTaximeter
canonly take place after itshasbeen installed once and forallon
thevehicle cfwhich itforms anintegral part ,itwasnotpossible to
•carry outalltheoperations corresponding totheEECinitial verifi­
cation atthepoint ofmanufacture .Provision isthus made forinitial
verification tobecarried outintwostages *Attheend ofthefirst
stage ,which consists ofchecking theproper functioning andmetrolo­
gical characteristics oftheTaximeter ,that meter shall receive the
EECpartial initial verification mark provided forintheCouncil Di­
rective of26July 1971 ontheapproximation ofthelaws oftheMember
States relating tocommon provisions forboth measuring instruments
and methods ofmetrological control .

Aslaid down inArticle 3,this mark allows Taximeters access to
themarkets ofall theMember States ofthe Coi-'iruri ty. c<.
petent authorities oftheMember Statu whore such instruments will
beused must ofnecessity check that theinstallation onthe vehicle
hasbeen carried out correctly and must perform the final adjustments .
Articles hand 5arecommon toallDirectives ,Article 4contains
thewording proposed bytheEuropean Parliament forone ofthe re­
cent proposals .
II.HARMONISATION SOLUTION
Theharmonization solution adopted canonly beoftheoptional type *
Itwill ensure that Taximeters satisfying this Directive canbe
freely marketed and used intheMember States inthe same way as
Instruments which have satisfied thenational inspection procedures
ineach Member State .
This solution ,which ,incidentally ,isadopted forallmeasuring
instruments ,was the only method applicable inthis sector atpre­
sent .Aslong asthesubstance ofnon-technical provisions relating f
inter alia tothe field ofuse and tothe tariff regulations in
force remains asdivergent between thevarious Member States asat
present ,itwill bevery difficult toenvisage total harmonization .
III .CONSULTATION OFTHE PARLIAMENT AND THE ECONOMIC AND SOCIAL COMMITTEE
The opinion ofthese twoinstitutions isnecessary tocomply
with theprovisions ofArticle 100 ?paragraph 2.The implementa­
tion oftheprovisions laid down bytheDirective requires that
some Member States amend their laws .

ANNEX
1. Terminology
1.1. Tine-distance meters ,called "taximeters "
Time distance meters ,called taximeters ,areinstruments which ,
according tothecharacteristics ofthevehicle inwhich they
areinstalled and therates applied attheplace ofuse ,calcu­
late automatically andindicate constantly when inuse the
amounts tobepaid bytheusers ofpublic vehicles designated
astaxis asafunction ofthe distance covered and -below a
certain speed -ofthe time forwhich the vehicle isoccupied ,
exclusive ofvarious surcharges ,thelevying ofwhich may be
authorized bylocal regulations inforce intheMember States .
Inthis Annex ,such instruments arereferred toas"taximeters ".
1.2. Special terms used inthedocument
Thereading ofataximeter depends -the rate for fares apart -
onaconstant ,k,oftheinstrument andonacharacteristic
coefficient ,wfofthevehicle inwhich theinstrument isinstal­
led .This coefficient wisafunction ofthe effective cir­
cumference ,u,ofthewheels ofthevehicle and ofthe trans­
mission ratio ofthe number ofrevolutiens ofthe wheels to'the
number ofrevolutions ofthepart provided onthevehicle to
connect ittothe taximeter .
1.2.1 .Constant ,k,®fthetaximeter
The constant ,k,ofataximeter isacharacteristic quantity
that indicates the type andnumber ofsignals that theinstru­
ment must receive inorder togive correctly areading corres -*
ponding toadistance travelled of1km.
This constant ,k,isexpressed
(a)inrevolutions perindicated kilometre (rev/km)ifthein­
formation relating tothedistance travelled bythevehicle
isfed into the taximeter inthe form ofanumber ofrevo­
lutions ofitsmain shaft (drive shaft atpoint ofentry
totheinstrument ):
(b)inpulses perindicated kilometre (pulse /km)ifthis infor­
mation isfed ininthe form ofelectric signals .

-5-
According tothewayinwhich theinstrument isconstructed ,
constant kmay beinvariable orvariable byfixed amounts ,
1,2,2 ,Characteristic coefficient ,w,ofthevehicle
Thecharacteristic coefficient ofavehicle isaquantity in­
dicating the -type andnumber ofsignals intended todrive the
taximeter anddisplayed atthecorresponding part provided for
this purpose inthevehicle ,for 1kilometre ofdistance tra­
velled * . ,
This coefficient wisexpressed s
(a)inrevolutions perkilometre travelled (rev/km),or
(b)inpulses perkilometre travelled (pulse /km),depending on
whether theinformation relating tothe distance travelled
bythe vehicle isinthe form ofthe number ofrevolutions
ofthepart driving the taximeter orinthe form ofelectric
signals *
This coefficient varies asafunction ofseveral factors ,in
particular thewear andpressure ofthe tyres ,the load carried
bythevehicle and theconditions inwhich thejourney ismade .
' Itmust bedetermined under thestandard testing conditions
f^rthevehicle (Section 1.2.6.),
1,2,3»Effective circumference ,u,(mm)ofthewheels
Effective circumference ,u,ofthewheel ofthevehicle which
drives thetaximeter directly orindirectly isthedistance
travelled bythevehicle during onecomplete revolution ofthis
wheel .When twowheels drive thetaximeter jointly ,the -effec­
tive circumference isthe mean ofthe effective circumferences
ofeach ofthetwowheels ,expressed inmillimetres .
Effective circumference ,u,iscorrelated with characteristic
coefficient ,w,ofthevehicle (Section 1.2.2.),andconsequent­
lythis circumference ,ifitisnecessary toknow it,must
also bedetermined under theconditions given inSection 1,2.6,
1«2,*f ,Adapting device ' .
Inaccordance with thedefinitions given above fork(Section
1,2.1 ,)andfor w(Section 1.2 .2.),thevalues ofthese quan­
tities must beequal ifthetaximeter istorecord correctly
the distances travelled ,
'Aspecial device enables oneofthetwovalues tobeadjusted
tothe other .

1.2.5 .Errors anddispersion ofreadings
The dispersions and errors mentioned inSection 5are instru­
mental dispersions and errors ,i.e. they originate solely from
theinstruments independently ofthe vehicles .
Thespread (range ofdispersion )ofthereadings isexpressed
asthegreatest difference between thereadings from ataxi­
meter which correspond toagiven value ofthequantity measured .
* t
1.2.6 .Standard testing conditions forthevehicle (where inspection
oftaximeters isconcerned )
The "standard testing conditions for thevehicle "are fulfilled
when :
(a)Thetyres fitted tothewheel orwheels driving the taxi-
deter are ofthe model which has the same effective circum­
ference value ,u,asthewheels that were used todeter­
mine characteristic ceefficient ,w.
They must beingood condition and beinflated tothepres­
sure prescribed bythemanufacturer .
(b)Theload carried bythevehicle is150kg,which corresponds
byconvention totheweight oftwoadults ,including the
driver ."
(c)Thevehicle ,propelled byitsengine ,travels inastraight
line onflat ,horizontal ground ataspeed of^0km/h.
Where thetests arecarried outunder different conditions (e,.g .
atdifferent weights ,different speeds ,bench tests ,etc.),
their results will becorrected bythe coefficients forconver­
sion needed toconvert their value tothat which would have
been obtained under the "normal test conditions "defined above .
2. Authorized units ofmeasurement
Thefollowing units ofmeasurement areauthorized forthe
readings avoided ordisplayed bytaximeters :
-themetre orthekilometre ,fordistance .However ,until
expiry ofthetransitional period during which theuse of
measurement units under theImperial System ,given inAn­
nex IItotheCouncil Directive of18October 1971 onunits
ofmeasurement ,isauthorized within theCommunity ,distances
may beexpressed inyards ormiles intheUnited Kingdom or
Ireland ifthose countries sodesire ;
•/•

-thesecond ,theminute ,orthehour ,fortime .

3. Technical characteristics .
3.t« Measuring device andcalculating device
3.1.1 .The taximeter must besoconstructed astocalculate and indi­
cate the fare 6olely onthe basis of :
•141
(a)thodistance travelled (distance-based drive )when the
vehicle ismsving ataspeed greater than agiven speed
(speed atwhich thedrive base changes )}
(b)thetime (time-based drive )when thevehicle ismoving at
aspeed below this given speed .
'Thespeed atwhich thedrive base changes isthat corresponding
tothefare rate applied inthecase oftime-based drive ,di­
vided bythe rate applied when the taximeter isoperating in
the distance-based mode .
The above-mentioned speed atwhich thedrive base changes varies
asafunction oftherates per hour andperkilometre ,which
may bemodified inaccordance with Section 3*1*5 *
3.1.2 .Thedistance-based drive must beeffected bythewheels ,but
reversing thevehicle must not result inareduction inthe
fare ordistance indicated .-
i '' . . •
•Thetime-based drive must beeffected byamechanical orelec-
'trical clockwork movement which can beactivated only byopera­
ting the control switch ofthe taximeter .
Ifthemechanical clockwork movement ismanually wound ,itmust
function foreight hours atleast without having toberewound ,
orfortwohours ifthere isawinding system connected with
each manual movement leading toactivation ofthetaximeter .
Ifthemechanical cleckwork movement iselectrically wound ,
theprocess must beautomatic .
The electrical clockwork movement must beconstantly ready to
function .

With distance-based drive ,the first change inreading must
take place after aninitial distance ,laid down inaccordance
with thetariff regulations inthevarious Member States ,has
been covered .The subsequent changes onthe indicator must
correspond toequal distance intervals .
With time-based drive ,the first change inreading must take
place after aninitial time lapse laid down inaccordance with
thenational tariff regulations .Thesubsequent changes on
theindicator must correspond toequal time intervals .
Without any change inthedrive base ,theratio between the
initial distance and thesubsequent distances must bethe same
asthat between theinitial time lapse and thesubsequent time
lapses ,whatever tariff isused .
Anadapting device (speed conversion device ),must enable cons­
tant kofthe taximeter tobeadapted tocharacteristic Value
wofthe vehicle towhich itisfitted .This device must be
soconstructed that noaccess toother parts ofthe taximeter
can begained byopening thehousing .
The taximeter must bedesigned insuch away that anymodifica­
tions tothe calculating device which are necessary tocomply
with rate changes required bythe tariff regulations inthe
various Member States can beeasily effected .
When theinstrument isequipped todeal with awider range of
rates than iscurrently inforce ,the taximeters must ,inall
thesupernumerary positions ,calculate andindicate afare
based onone ofthe rates authorized bythe tariff regulations
inthe various Member States .
Control switch
Themechanism ofthe taximeter must not becapable offunction­
inguntil ithas been activated by ,asingle control switch
turned toone ofthe following authorized positions :
"FORHIRE "position
Inthe "FOR HIRE "position :
(a)There shall benoindication ofafare tobepaid ,orthis
indication shall beequivalent tozero ;
(b)Thedistance-based .drive andthetime-based drive must not

(b)a"FARE "position fixing thefinal amount tobepaid bythe
passenger for the journey ,exclusive ofanysurcharge .In
this position ,the tirae-based drive must bedisconnected
and the distance-based drive must beswitched tothe rate
authorized bytherelevant regulations intheMember States .
Operation ofthe control switch issubject tothe following
restrxctxons :
«
(a)starting from anoperating position atanyfare rate ,the
taximeter must not be .capable ofbeing returned tothe
"FORHIRE "position without passing through the "FARE "
position .However ,transition from one rate toanother
must still bepossible ; ,
...(b)starting from the "FARE "position ,thetaximeter must not
