5. Title, number of pages and language(s) of the notified document : Proyecto de 
Norma Metrológica Peruana PNMP 024:2016 "Instrumentos de medición de gases de 
escape de vehículos - Parte 1 : Requisitos metrológicos y técnicos y Parte 2 : Controles 
metrológicos y ensayos de funcionamiento"  (Draft Peruvian Metrology Standard ( PNMP ) 
No. 024:2016, Instruments for measuring vehicle exhaust emissions - Part 1 : Metrological 
and technical requirements , and Part 2 : Metrological controls and performance tests)  
6. Description of content : The notified  draft Peruvian Metrology Standard specifies the 
metrological and technical requirements and tests for digital measuring instruments 
(hereafter termed "instrument(s) ") that serve to d etermine the volume fractions of certain 
components of the exhaust gases emanating from motor vehicles . The conditions with 
which such instruments must comply in order to meet any OIML performance requirements 
are also established.  
It is applicable to inst ruments, particularly those used according to the procedure defined 
in ISO 3929, intended for the inspection and maintenance of in -use motor vehicles with 
spark -ignition engines . These instruments are used to determine the volume fraction of 
one or more of  the following exhaust gas components : carbon monoxide (CO), carbon 
dioxide (CO 2), hydrocarbons (HC, in terms of n -hexane) and oxygen (O 2), at the moisture 
level of the sample as analy sed.  G/TBT/N/PER/91

  7. Objective and rationale, including the nature of urgent proble ms where 
applicable : The vehicle stock is the main emitter of air pollutants in Lima . Gases and 
particulate matter are the pollutant substances generated  during  the combustion process 
and expelled through the exhaust pipe . Carbon monoxide and carbon dioxid e are the main 
gases emitted by vehicles . Carbon monoxide inhibits the transport of oxygen in the blood ; 
exposure to this gas  may therefore be fatal , depending on its concentration in the air and 
the duration of exposure . Carbon dioxide is the main greenho use gas that causes climate 
change . It is therefore vital to control the se gases in order to  prevent and/or mitigat e 
damage to public health and the environment.   
Official control of pollutant emissions from motor vehicles takes place during motor vehicle 
inspection s and involves  testing carried out  using  vehicle exhaust emission analy sers to 
determine compliance with the maximum permitted  emission levels.   
In accordance with the provisions of Supreme Decree No. 047-2001-MTC, the vehicle 
exhaust emission analysers used for the official control of pollutant emissions from motor 
vehicles must be approved and authorized by the Ministry of Transport and 
Communications, through the Directorate -General of S ocial and Environmental Affairs.  
Approval must be on the b asis of  one of the following standards:   
 OIML International Recommendation R 99 ; 
 US Standard  BAR-97; or 
 ISO 3930 . 
Draft Peruvian Metrology Standard ( PNMP ) No.  024:2016 ( Instruments for measuring 
vehicle exhaust emissions - Part 1 : Metrological and technica l requirements , and Part 2 : 
Metrological  controls and performance tests)  is an adoption of International Organization of 
Legal Metrology (OIML) International Recommendation R 99 -1&2:2008, "Instruments for 
measuring vehicle exhaust emissions".  
8. Relevant documents : OIML International Recommendation R 99 -1&2:2008, "Instruments 
for measuring vehicle exhaust emissions"  
9. Proposed date of adoption : - 
Proposed date of entry into force : -
