MEPS for Distribution transformer: TCVN 8525: 2010 (applied by 78/2013/QD-TTg)

Source: International Energy Agency
Last updated: 4 November 2019

This standard is adopted based on the title year, but only takes effect in the market based on the following laws:

    • Decision 51/2011/QD-TTg & Decision 03/2013/QD-TTg stipulates the list of equipment subject to energy labelling program, application of MEPS and the roadmap.
          1. For home appliances group: As of January 1, 2014, it is not allowed to import and produce devices with energy efficiency below the minimum energy efficiency.
          2. For industrial equipment, office equipment and commercial equipment: From January 1, 2015, it is not allowed to import and produce equipment with energy efficiency levels below the minimum energy efficiency.
          3. For round light products (incandescent lamps): From January 1, 2013, it is forbidden to import, produce and circulate lamps with a capacity of greater than 60 W.
    • Decision 78/2013/QD-TTg, stipulates the list of equipment and roadmap for rejecting lower than MEPS appliance/equipment
          1. For household appliances and industrial equipment: From January 1, 2015, it is not allowed to import and produce equipment with energy efficiency levels below the minimum energy efficiency.
