The EN 12309 standards series has been restructured and supplemented: EN 12309-1 and EN 12309-2 of the new EN 12309 supersede EN 12309-1:1999 while the Part 1 and the Parts 3 to 7 of EN 12309 supersede EN 12309-2:2000. The present EN 12309-3 specifies the test conditions for the rating of energy parameters of monovalent gas-fired sorption appliances for heating and/or cooling with a net heat input not exceeding 70 kW.
This document replaces DIN EN 12309-2:2000-06 .
