Overview

DIN EN 12599 contains the German version of EN 12599:2012 which has been prepared by Technical Committee CEN/TC 156 "Ventilation for buildings" (secretariat: BSI, United Kingdom) at the European Committee for Standardization (CEN). NA 041-02-50 AA "Grundlagen (SpA CEN/TC 156 und ISO/TC 205/WG 4)" ("Fundamentals (Mirror Committee CEN/TC 156 and ISO/TC 205/WG 4)") of the Heating and Ventilation Technology Standards Committee (NHRS) at DIN, the German Institute for Standardization e. V., has been involved in the preparation of this standard. EN 12599:2012 specifies checks, test methods and measuring instruments in order to verify the fitness for purpose of the installed systems primarily for handing over which will be partially performed before, during and after handing over. It enables the choice between simple test methods, when sufficient, and extensive measurements, when necessary, and applies to mechanically operated ventilation and air conditioning systems as specified in EN 12792 and comprising any of the following: - air terminal devices and units; - air handling units; - air distribution systems (supply, extract, exhaust); - fire protection devices; - automatic control devices. When the system is set, adjusted and balanced measurement methods described in EN 12599:2012. EN 12599:2012 only applies to ventilation and air conditioning systems designed for the maintenance of comfort conditions in buildings however, and is not applicable in the case of systems for the control of industrial or other special process environments. In the latter case however, this standard may be referred to if the system technology is similar to that of the aforementioned ventilation and air conditioning systems. EN 12599:2012 may also be used for residential and dwelling ventilation systems. The measuring methods in EN 12599:2012 can be used in the frame of the energy inspection of air conditioning systems according to EU Directive 2010/31/EU "Energy performance of buildings Directive" (see EN 15239, EN 15240). The standard 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. EN 12599:2012 supersedes DIN EN 12599:2000. The following modifications have been made: a) the scope has been modified so that the test methods and measuring instruments can be used before, during and after handing over instead of only at the stage of handing over, and also in the frame of Energy Performance of Buildings Directive measurements; b) the scope has been modified so that EN 12599 does not exclude dwellings; c) normative references have been updated; d) Table 1 now includes requirements for the cleanliness and leakage of the system; e) in Table 2, the uncertainty of the air flow rate has been reduced from ± 20 % to ± 15 % for each individual room and from ± 15 % to ± 10 % for each system; f) a formula to calculate the uncertainty of the measuring location has been added to Table E.4; g) methods to measure the electrical power have been added.
