4. Products covered (HS or CCCN where applicable, otherwise national tariff 
heading . ICS numbers may be provided in addition, where applicable) : The 
notified draft Mexican Official Standard establishes the safety requirements and technical 
guidelines for the national transmission network and the general distribution networks, 
which are part of the National Electricity System, in addition to a conformity assessment 
procedure.  
The notified Standard also outlines the obligations and responsibilities of the federal, state 
and municipal authorities and individuals to ensure that the saf ety conditions specified 
during the design and construction of the facilities are met once the electrical 
infrastructure being incorporated into the National Electricity System's national 
transmission network and general distribution networks has been buil t and enters into 
operation . 
The notified Standard applies to the elements that make up the national transmission 
network and the general distribution networks and that are owned by or under the 
physical control of the transporter or distributor, regardles s of where they are located.  
The requirements and guidelines established in the notified Standard are geared towards 
ensuring the safety of those in the vicinity of the general distribution networks and the 
national transmission network, taking into accoun t the conditions for their design, 
construction and entry into operation.  
Furthermore, it establishes the guidelines and safety requirements to be met by the 
authorities and individuals once the electrical facilities of the national transmission 
network an d the general distribution networks have entered into operation, with a view 
to ensuring that the safety distances with the electrical facilities of the national G/TBT/N/MEX/463/Rev.2  
- 2 - 
  transmission network and the general distribution networks are observed at all times to 
protec t human safety.  
The low voltage electrical facilities in the substations that form part of the national 
transmission network and the general distribution networks are excluded from this 
Standard.
