ÖNORM EN 1397

This European Standard applies to room fan-coil units using hot or chilled water or water mix tures. It applies to units designed for an air flow of not more than 0,7 m3/s and an extemal static pressure due to duct resistance of 65 Pa max. Air heating may be achieved by means of electrical resistance heaters. This standard specifies uniform methods of testing under non frosting conditions, conducted on test samples to test and ascertain the following at the specified standard conditions: - product identification; - performance on condensation on the casing; - capacity; - perfomance on condensate disposal; - liquid side pressure drop; - air volume flow rate; - sound power level. This standard does not Cover technical safety aspects. It is not the purpose of this standard to specify the tests used for production or field testing.
