En gasblander eller -mikser anbefales, når justeringsgasser fortyndet i N2 skal blandes med justeringsgasser fortyndet med luft.
A gas blending or mixing device is recommended when blending span gases diluted in N2 with span gases diluted in air;
Ved hjælp et gasdeleapparat blandes en justeringsgas af NO–CO–CO2–C3H8–CH4 (resten N2) ligeligt med en justeringsgas af NO2, resten renset syntetisk luft.
Using a gas divider, an NO–CO–CO2–C3H8–CH4 (balance N2) span gas shall be equally blended with a span gas of NO2, balance purified synthetic air.
Hvis det er relevant, kan der anvendes standard binære justeringsgasser i stedet for justeringsgasblanding af NO-CO-CO2-C3H8-CH4, resten N2. I så fald skal der foretages separate responsprøvninger for hver analysator.

Der skal anvendes en opstillingsmetode, der forhindrer trykudsving forårsaget af standsning af strømmen gennem gasblanderanordningen.
A setup that avoids pressure pulsations due to stopping the flow through the gas blending device shall be used.
Hvis nogen af disse gasbestanddele ikke er relevante for den pågældende analysatorverifikation, udelades de.
Any of these gas constituents if they are not relevant to the analysers for this verification shall be omitted.
Som alternativ tillades brug af gasflasker med enkeltgasser og separat måling af responstider.
Alternatively the use of gas bottles with single gases and a separate measurement of response times is allowed;
Dataindsamlingen foretages således:
Data collection shall be done as follows:
Ventilen indstilles, så den starter strømmen af nulstillingsgas.
The valve shall be switched to start the flow of zero gas;
Stabilisering sikres, idet der tages højde for transportforsinkelser og fuld respons fra den langsomste analysator.

The data from sub-paragraph (c) of paragraph 8.1.5.4. of this section shall be used to calculate the mean rise time, T10–90 for each of the analysers.
Hvis det vælges at godtgøre overensstemmelse med litra b), i), i punkt 8.1.5.3 i dette afsnit, skal følgende procedure anvendes: Stigningstiderne (i sekunder) ganges med deres respektive registreringsfrekvenser i Hertz (1/s).
If it is chosen to demonstrate compliance with sub-paragraphs (b) (i) of paragraph 8.1.5.3. of this section, the following procedure has to be applied: The rise times (in s) shall be multiplied by their respective recording frequencies in Hertz (1/s).
Værdien for hvert resultat skal mindst være 5.
The value for each result shall be at least 5.
Hvis værdien er mindre end 5, forhøjes registreringsfrekvensen eller strømningerne justeres eller prøvetagningssystemet ændres, således at stigningstiden øges efter behov.
If the value is less than 5, the recording frequency shall be increased or the flows adjusted or the design of the sampling system shall be changed to increase the rise time as needed.
Desuden kan der konfigureres digitale filtre, som øger stigningstiden.
Also digital filters may be configured to increase rise time;
Hvis det vælges at godtgøre overensstemmelse med litra b), ii), i punkt 8.1.5.3. i dette afsnit er det tilstrækkeligt at godtgøre overensstemmelse med kravene i litra b), ii) i punkt 8.1.5.3.
If it is choosen to demonstrate compliance with sub-paragraphs (b) (ii) of paragraph 8.1.5.3. of this section, the demonstration of compliance with the requirements of sub-paragraphs (b) (ii) of paragraph 8.1.5.3. is sufficient.
Verifikation af responstid for analysatorer af kompensationstypen
Response time verification for compensation type analysers
Denne verifikation foretages for at bestemme en kontinuerlig gasanalysators respons, hvor én gasanalysators respons kompenseres af en andens med henblik på at kvantificere de forurenende luftarter.
This verification shall be performed to determine a continuous gas analyser's response, where one analyser's response is compensated by another's to quantify a gaseous emission.
I den forbindelse skal vanddamp anses for at være en gasformig bestanddel.
For this check water vapour shall be considered to be a gaseous constituent.
Denne verifikaton er påkrævet for kontinuerlige gasanalysatorer, der anvendes til transient prøvning eller RMC-prøvning.
This verification is required for continuous gas analysers used for transient or ramped-modal testing.
Denne verifikation er ikke nødvendig for gasanalysatorer til batchprøvetagning eller for kontinuerlige gasanalysatorer, som kun anvendes til prøvning i diskret modus.
This verification is not needed for batch gas analysers or for continuous gas analysers that are used only for discrete-mode testing.
Denne verifikation finder ikke anvendelse på korrektion for vand, der er fjernet fra prøven ved efterbehandlng, og heller ikke på NMHC-bestemmelse fra THC og CH4, som omhandlet i tillæg A.7 og A.8 vedrørende emissionsberegning.
This verification does not apply to correction for water removed from the sample done in post-processing and it does not apply to NMHC determination from THC and CH4 quoted in Appendices A.7 and A.8 concerning the emission calculations.
Denne verifikation foretages efter opstilling (dvs. efter ibrugtagning af prøvningsrum).
This verification shall be performed after initial installation (i.e. test cell commissioning).
Efter større vedligeholdelsesindgreb kan den ensartede respons verificeres som beskrevet i punkt 8.1.5, forudsat at der på et tidspunkt er foretaget fugtmættet ensartet responsverifikation af eventuelle udskiftede komponenter.
After major maintenance, paragraph 8.1.5. may be used to verify uniform response provided that any replaced components have gone through a humidified uniform response verification at some point.
Ved hjælp af denne procedure verificeres tidsjusteringen og den ensartede respons ved kontinuerlige kombinerede gasmålinger.
This procedure verifies the time-alignment and uniform response of continuously combined gas measurements.
I den forbindelse er det nødvendigt at sikre, at alle kompensationsalgoritmer og fugtighedskorrektioner er aktiveret.
For this procedure, it is necessary to ensure that all compensation algorithms and humidity corrections are turned on.
De generelle krav til responstid og stigningstid angivet i litra a), punkt 8.1.5.3, gælder også for analysatorer af kompensationstypen.
The general response time and rise time requirement given in sub-paragraph (a) of 8.1.5.3. is also valid for compensation type analysers.
Hvis registreringsfrekvensen afviger fra opdateringsfrekvensen for det kontinuerligt kombinerede signal, skal det laveste af de to frekvenser anvendes til den påkrævede verifikation i litra b), i), i punkt 8.1.5.3.
Additionally, if the recording frequency is different than the update frequency of the continuously combined/compensated signal, the lower of these two frequencies shall be used for the verification required by sub-paragraphs (b) (i) of paragraph 8.1.5.3.
Alle procedurer i litra a)-c), punkt 8.1.5.4, skal anvendes.
All procedures given in sub-paragraphs (a) - (c) of paragraph 8.1.5.4. have to be used.
Desuden måles også responstid og stigningstid for vanddamp, hvis der anvendes en kompensationsalgoritme, som er baseret på målt vanddamp.
Additionally also the response and rise time of water vapour has to be measured, if a compensation algorithm based on measured water vapour is used.
I så fald skal mindst én af de anvendte kalibreringsgasser (men ikke NO2) fugtmættes som følger:
In this case at least one of the used calibration gases (but not NO2) has to be humidified as follows:
Hvis systemet ikke anvender en prøvetørrer til at fjerne vandindholdet i gasprøven, fugtmættes justeringsgassen ved at sende gasblandingen gennem en lukket beholder, som fugtmætter gassen til det anslåede højeste prøvedugpunkt under emissionsprøvetagningen, idet den bobles igennem destilleret vand.
If the system does not use a sample dryer to remove water from the sample gas, the span gas shall be humidified by flowing the gas mixture through a sealed vessel that humidifies the gas to the highest sample dew point that is estimated during emission sampling by bubbling it through distilled water.
Hvis systemet anvender en prøvetørrer under prøvningen, der har bestået verifikationskontrollen for prøvetørrere, kan den fugtmættede gasblanding indføres nedstrøms for prøvetørreren ved at boble den gennem destilleret vand i en lukket beholder ved 25 ± 10 °C eller en temperatur over dugpunktet.
If the system uses a sample dryer during testing that has passed the sample dryer verification check, the humidified gas mixture may be introduced downstream of the sample dryer by bubbling it through distilled water in a sealed vessel at (25 ± 10 °C), or a temperature greater than the dew point.
I alle tilfælde skal den fugtmættede gas nedstrøms for beholderen fastholdes på en temperatur, som ligger mindst 5 °C over dens lokale dugpunkt.
In all cases, downstream of the vessel, the humidified gas shall be maintained at a temperature of at least 5 °C above its local dew point in the line.
Bemærk, at det er muligt at udelade en hvilken som helst af disse gasbestanddele, hvis de ikke er relevante for analysatorerne i den pågældende verifikation.
Note that it is possible to omit any of these gas constituents if they are not relevant to the analysers for this verification.
Hvis nogen af gasbestanddelene ikke er modtagelige for vandkompensation, kan responskontrollen for disse analysatorer foretages uden fugtmætning.
If any of the gas constituents are not susceptible to water compensation, the response check for these analysers may be performed without humidification.

Measurement of engine parameters and ambient conditions
Motorfabrikanten skal anvende interne kvalitetsprocedurer, der kan henføres til anerkendte nationale eller internationale standarder.
The engine manufacturer shall apply internal quality procedures traceable to recognised national or international standards.
I modsat fald finder følgende procedurer anvendelse.
Otherwise the following procedures apply.
Kalibrering af drejningsmoment

Det skal sikres, at vægtenes vippearm er vinkelret på tyngdepunktet (dvs. horisontal) og vinkelret på dynamometerets rotationsakse.
It shall be made sure that the weights' lever arm is perpendicular to gravity (i.e., horizontal) and perpendicular to the dynamometer's rotational axis.
Der anvendes mindst seks kombinationer af kalibreringsvægte for hvert relevant momentmåleområde, idet vægtmængden fordeles ligeligt i hele området.
At least six calibration-weight combinations shall be applied for each applicable torque-measuring range, spacing the weight quantities about equally over the range.
Dynamometeret oscilleres eller roteres under kalibreringen for at reducere statisk friktionshysterese.
The dynamometer shall be oscillated or rotated during calibration to reduce frictional static hysteresis.
Kraften af den enkelte vægt bestemmes ved at multiplicere den internationalt sporbare masse med den lokale acceleration af jordens tyngdekraft.
Each weight's force shall be determined by multiplying its internationally-traceable mass by the local acceleration of Earth's gravity.
Kalibrering af trykføler eller prøvering
Strain gage or proving ring calibration
Ved denne teknik påføres kraft enten ved at hænge vægte på en vippearm (disse vægte og deres vippearmslængde indgår ikke i bestemmelsen af referencemomentet) eller ved at betjene dynamometeret ved forskellige momenter.
This technique applies force either by hanging weights on a lever arm (these weights and their lever arm length are not used as part of the reference torque determination) or by operating the dynamometer at different torques.
Der anvendes mindst seks kraftkombinationer for hvert relevant momentmåleområde, idet kraftmængden fordeles nogenlunde ligeligt i hele området.
At least six force combinations shall be applied for each applicable torque-measuring range, spacing the force quantities about equally over the range.
I dette tilfælde bestemmes referencedrejningsmomentet ved at multiplicere kraft-output fra referencemeteret (f.eks. en trykmåler eller prøvering) med den effektive vippearmslængde, som måles fra det punkt, hvor kraftmålingen foretages til dynamometerets rotationsakse.
In this case, the reference torque is determined by multiplying the force output from the reference meter (such as a strain gage or proving ring) by its effective lever-arm length, which is measured from the point where the force measurement is made to the dynamometer's rotational axis.
Det skal sikres, at denne længde måles vinkelret på referencemeterets måleakse og vinkelret på dynamometerets rotationsakse.
It shall be made sure that this length is measured perpendicular to the reference meter's measurement axis and perpendicular to the dynamometer's rotational axis.

This section describes how to calibrate flow-meters for diluted exhaust constant-volume sampling (CVS) systems;
Denne kalibrering foretages, mens flowmeteret er monteret i dets permanente position.
This calibration shall be performed while the flow-meter is installed in its permanent position.
Denne kalibrering foretages, efter at en del af flowkonfigurationen opstrøms eller nedstrøms for flowmeteret er blevet ændret på en måde, der kan indvirke på flowmeterets kalibrering.
This calibration shall be performed after any part of the flow configuration upstream or downstream of the flow-meter has been changed that may affect the flow-meter calibration.
Denne kalibrering udføres efter opstilling af CVS-systemet, og når et korrigerende indgreb ikke resulterer i overholdelse af verifikationen for fortyndet udstødningsstrøm (dvs. propankontrol) i punkt 8.1.8.5.
This calibration shall be performed upon initial CVS installation and whenever corrective action does not resolve a failure to meet the diluted exhaust flow verification (i.e., propane check) in paragraph 8.1.8.5.;
Dette referenceflowmeters respons på strømning anvendes som referenceværdi til kalibrering af CVS-flowmeter.
This reference flow-meter's response to flow shall be used as the reference value for CVS flow-meter calibration;
Der må ikke anvendes opstrømsskærm eller anden begrænsning, som kan påvirke strømningen foran referenceflowmeteret, medmindre flowmeteret er blevet kalibreret med en sådan begrænsning.
An upstream screen or other restriction that could affect the flow ahead of the reference flow-meter may not be used, unless the flow-meter has been calibrated with such a restriction;
Den kalibreringssekvens, der er beskrevet i dette punkt 8.1.8.4, henviser til den molbaserede tilgang.
The calibration sequence described under this paragraph 8.1.8.4. refers to the molar based approach.
