This Official Mexican Standard establishes the requirements and specifications for the design, construction and pre-start, operation, maintenance, closing and dismantling of transportable Storage Modules, as well as the Stations of Supply of Compressed Natural Gas for motor vehicles that use it as fuel.

The Standard explains that due to the characteristics of CNG station facilities and locations, which coexist in urban areas with high population rates, it is necessary for these activities to be carried out in compliance with the requirements and design specifications, construction, pre-start, operation, maintenance, closing and dismantling; to guarantee its development in a safe way.

The Standard applies throughout the national territory and is applicable to:

A. The Load Terminals of Transportable Storage Modules by Semitrailer, from the Natural Gas Inlet Valve to the Compression System to the CNG Transfer Point to the Transportable Storage Modules of the Semitrailer;

B. The supply stations to motor vehicles, from the valve of entry of Natural Gas to the System of Compression until the Point of Transfer of the CNG to the vehicular systems;

C. Transportable Storage Module Discharge Terminals per Semi-trailer, from the CNG Module reception area to the CNG delivery valve to the user, to the decompression facility or to the satellite station; and

D. The Satellite Stations from the point of reception of CNG to the Point of Transfer of the CNG to the vehicular systems.

Various non-inclusions are stated, including vehicles for the transport of CNG containers, vehicle recharge devices, and integrated CNG compression and dispensing equipment.
