Official Standard PROY -NOM-001-CRE/SCFI -2017, Electrical power measurement systems . 
Metrology specifications, test methods and conformity  assessment  procedure) (243 pages, 
in Spanish)  
6. Description of content : The notified draft Mexican Official Standard applies to meters 
and measuring transformers used for settlement and billing purposes, and for measuring 
instantaneous values and power q uality, which are factors in:  
(a) the determination of electrical energy costs (local marginal price);  
(b) the power market (related services);  
(c) the availability of controllable demand;  
(d) the physical network model ; and/or  
(e) the evaluation of compliance with obligations and market rules.  
Exclusions  
The notified draft Mexican Official Standard establishes the minimum requirements for the 
regulation of the metrological characteristics of electric energy meters and instrument 
transformers, and the  basic functions that have an impact on the measurements according 
to their application ; it does not take into account other specifications or specific functional 
characteristics, such as design, technology and algorithms.  
In view of the above, in addition  to compliance with this draft Standard, other applicable 
technical regulations authorized by the competent authority must be observed to ensure 
the correct use and performance of meters and instrument transformers.  G/TBT/N/MEX/389

  7. Objective and rationale, including t he nature of urgent problems where 
applicable : The notified draft Mexican Official Standard establishes the metrological 
specifications, test methods and conformity  assessment  procedure to be applied to meters 
and measuring transformers used for the wholes ale electricity market and basic power 
supply.
