Mexico Adopts New Standards for Systems to Measure Electricity
The Mexican government has established new mandatory standards for domestically-produced and imported systems to measure electricity. Effective 14 March, subject merchandise will be required to comply with the minimum technical and metrological parameters of NOM-EM-007-CRE-2017, which include definitions; safety and technical specifications; integrity specifications; review and testing procedures; conformity assessment procedures; and provisions regarding equipment used in public lighting, compliance with international standards, and recognition of international certificates and test reports. Since NOM-EM-007-CRE-2017 is an emergency regulation, it will remain in place only for a period of six months from 14 March, with the possibility of being renewed for an additional six-month term.
