Mexico first adopted energy efficiency standards in 1995 under the National Commission for Energy Saving (CONAE). In 1995, Mexico also introduced the Sello FIDE, a voluntary energy efficiency endorsement label awarded by the Fideicomiso para el Ahorro de Energía Eléctrica (FIDE). In 2008, the Law for Sustainable Use of Energy transferred authority for energy efficiency standards from CONAE to the just-created National Commission for Energy Efficiency (CONUEE). CONUEE has established energy efficiency standards for a total of 15 product categories and seven system categories. CONUEE also regulates a mandatory comparative energy label for domestic appliances.
Development of standards includes both the minimum energy performance levels (MEPS) required and the test procedure for determining the equipment performance. CONUEE is in charge of verifying compliance. Products that require mandatory comparative labels are rated as part of the MEPS process, and the labels for these products show the products’ efficiency levels in comparison to the MEPS level.
The Law for Sustainable Use of Energy establishes a set of specific and generic public and private organizations – described below – to develop standards and monitor compliance.
Public organizations include:
- National Standardization Commission (Comisión Nacional de Normalización): The main function of the Commission is to coordinate standardization activities at a national level. The Commission’s chair rotates among the participating ministries.
- National Standards Advisory Committees (Comités Consultivos Nacionales de Normalización): Each committee is chaired by the corresponding ministry. For energy efficiency standards, the advisory committee is chaired by CONUEE.
- General Direction of Standards (Dirección General de Normas, or DGN) of the Secretariat of the Economy (Secretaría de Economía). The Secretariat of the Economy enacts Normas Oficiales Mexicanas (NOM) related to user safety and commercial information and practices (e.g., food labels). DGN approves testing laboratories.
- National Metrology Center (Centro Nacional de Metrología): This is the primary calibration laboratory.
Private organizations include:
- Accreditation entities (Entidades de acreditación). These organizations, such as the Entidad Mexicana de Acreditación (EMA), are in charge of recognizing the technical competence and trustworthiness of certification organizations, testing laboratories, calibration laboratories, and verification units.
- Certification organizations (Organismos de certificación): These are organizations, such as the Asociación de Normalización y Certificación, A.C. (ANCE), whose objective is to certify compliance with standards. They require approval by the corresponding ministries.
- Test laboratories (Laboratorios de pruebas): These test laboratories products under NMX and NOM and can be either independent or operated by manufacturers.
- Verification Units (Unidades de verificación): These entities issue technical reports that demonstrate compliance with Normas Mexicanas (NMX) and NOM.
- Calibration laboratories (Laboratorios de calibración)
- National normalization organizations (Organismos nacionales de normalización): These are organizations whose objective is to elaborate (non-mandatory) Mexican Standards.
The figure below shows the relationship among organizations within Mexico's S&L program.
Legislative S&L History
Mexico's mandate for energy efficiency standards comes from a generic law, the Ley Federal Sobre Metrología y Normalización of July 16, 1992, which defines two types of standards: voluntary standards called Normas Mexicanas (NMX) and mandatory standards called Normas Oficiales Mexicanas (NOM). Regulations apply to products that are marketed in Mexico. The legal basis for the Secretariat’s mandate in energy efficiency is established in the Law for the Public Federal Administration, which aims to conserve non-renewable energy resources for future generations. CONUEE – an agency of the Secretariat – has been granted the authority to establish and operate the standards.
S&L Regulatory Process
The National Consultative Committee of Standards for the Preservation and Rational Use of Energy Resources (CCNNPURRE) (Comité Consultivo Nacional de Normalización para la Preservación y Uso Racional de los Recursos Energéticos) is responsible for reviewing all MEPS proposals. CONUEE presides over and defines membership in CCNNPURRE, which includes representatives from the Secretariats of Economy. CCNNPURRE comments are incorporated within 30 days of MEPS review and the proposal is then published in the Diario Oficial de la Federación (DOF). A period of 60 days for public comment is followed by another 45 days of consultation within CCNNPURRE to incorporate the public comments and approve the final MEPS and/or label and its publication in the DOF.
To display the voluntary endorsement label, Sello FIDE, manufacturers are required to submit certified test results on their products to confirm that they meet the Sello FIDE requirements. A certified laboratory tests the product to verify manufacturer claims. If approved, manufacturers pay for certification and sign an agreement stipulating the length of validity of the Sello FIDE endorsement; how the Sello FIDE can be displayed; and issues related to cancellation of certification. Manufacturers can then display the Sello FIDE on their products.
