Mexico Proposes New Standards for Solar Water Heaters
The Mexican government is seeking input from interested parties by 21 October on a proposal to establish new mandatory standards for solar water heaters with a thermal tank of less than 500 litres, for household and commercial use, with or without a backup liquefied gas or natural gas energy source. PROY-NOM-027-ENER/SCFI-2016 would set thermal performance and gas saving specifications, including conditions regarding external and internal thermal shocks; penetration by rain; resistance to high temperature, positive and hydrostatic pressure, overheating, icing and impact; thermal tank capacity; disassembly and final inspection; and minimum components. The proposal also includes sampling, test method, labelling and conformity acceptance provisions. The new requirements would enter into force 90 days from the date of publication of a final regulation in Mexico’s official journal.
