ENV 308:1991

Heat exchangers - Test procedures for establishing performance of air to air and flue gases heat recovery devices

Scope

This European prestandard describes methods to be used for laboratory testing of air-to-air heat recovery devices or those recovering heat from flue gases of heating appliances in buildings (except process-process applications), to obtain rating data. It gives test requirements and procedures for performing data given by the manufacturer. For the purpose of this standard, the term exhaust air may also be taken to mean the products of combustion.
