5. Title, number of pages and language(s) of the notified document : PROY-NOM-003-
ASEA -2016, Distribución de gas natural y gas licuado de petróleo por ductos  (Draft 
Mexican Of ficial Standard PROY -NOM-003-ASEA -2016: Pipeline distribution of natural gas 
and liquefied petroleum gas)  
6. Description of content : Opening up the natural gas industry to private initiative in 
respect of natural gas transport, storage and distribution ha s made it necessary to 
establish rules for ensuring a reliable, stable, safe and continuous distribution service in a 
climate of growth and technological development . Similarly, the pipeline transport and 
distribution of liquefied petroleum gas must meet m inimum safety requirements.  It is 
therefore necessary to introduce a Standard that establishes safety measures for the 
design, construction, operation  and maintenance of distribution systems.  
The notified draft Standard is applicable from the point of phys ical transfer between the 
transporter and the distributor, to the meter outlet or regulation and measuring station of 
the end user.  
The text does not set out to cover all the necessary requirements for the design, 
construction, testing, inspection, operati on, maintenance and safety of a distribution 
system . Aspects not covered by this draft Standard are covered by other relevant 
Standards.  G/TBT/N/MEX/325

  7. Objective and rationale, including the nature of urgent problems where 
applicable : The notified draft Mexican Offi cial Standard establishes the minimum 
requirements to be met by the design, construction, testing, inspection, operation, 
maintenance and safety of pipeline distribution systems for natural gas and liquefied 
petroleum gas.
