Mexico Considers New Technical Requirements for Certain Measuring Apparatus, Issues New Standards for Deep Well Pumps

The Mexican government will accept comments from interested parties through 6 July on a proposal (PROY-NOM-010-SCFI-2014) to amend the current technical and metrological requirements for non-automatic measuring apparatus. These instruments require the intervention of an operator during the weighing process to decide whether the weighing result is acceptable. The proposal includes references and definitions as well as general principles, metrological and technical requirements, specific requirements for electronic and other types of instruments, marking requirements and metrological controls. The new standard would enter into force 180 days from its date of publication in Mexico's official journal.

Comments may also be submitted by 5 July on separate proposals to update the current technical specifications, test methods and verification provisions for domestically-produced and imported (1) systems for measuring and delivering gasoline and other fuels (PROY-NOM-005-SCFI-2015); and (2) software and electronic systems to control the operation of systems for measuring and delivering gasoline and other fuels (NOM-185-SCFI-2015). PROY-NOM-005-SCFI-2015 sets forth definitions; technical specifications; sampling requirements; test methods; required marking information; requirements regarding initial, periodic and extraordinary verifications; conformity assessment; and enforcement. NOM-185-SCFI-2015 includes provisions in the areas of definitions and general terms, references, classification, general requirements and specifications for software evaluation, test methods, field verification, conformity assessment and enforcement. The updated standards would enter into force 60 days from their date of publication in Mexico's official journal.

Separately, the Mexican government has established new minimum electromechanical energy efficiency requirements for deep well pumping systems. Among other things, NOM-006-ENER-2015 sets new standards for pumping systems with a submersible motor as well as new conformity assessment procedures and documentary requirements. The new standards will enter into force on 18 September.
