BS EN 12599:2026

This document specifies checks, measurement methods and procedures in order to verify the fitness for purpose of the installed ventilation systems and air conditioning systems according to design. It establishes a procedure intended to technically support the handing over and inspection of these systems. This document enables the choice between checks and measurements when sufficient, and additional measurements, when necessary. This document applies to mechanical ventilation systems (including the mechanical part of hybrid systems) and full and (partial) air conditioning systems in non-residential (parts of) buildings. This document does not apply to: — heat generating systems and their control; — refrigerating systems and their control; — distribution of heating and cooling medium to the air handling units; — compressed air supplying systems; — water conditioning systems; — central steam generating systems for air humidifying; — electric supply systems. This document is not applicable to ventilation systems and air conditioning systems for industrial or other special process environments.
