List of a few NEN-EN (European) standards that relate to, among other things, ventilation, indicating which ones are in the Luka Quality Guide. (QG)
Luka Fitting Register, the so called LAR
The quality guarantee that comes with the Quality Certificate is dictated by an internationally supported aim to reduce the energy consumption of air handling units in buildings. The issuing of a Quality Certificate confirms that the entire air transport route, from the air handling unit to the ornaments, including the intermediate fittings, meets the standards as specified in the Luka Quality Guide.
In order to be able to guarantee the airtightness, class C, of the air transport route, the Luka members must have the results of airtightness measurements on fittings at their disposal.
In the "Luka Fitting Register ", the so called LAR, these results have been entered per type of fitting, with the corresponding supplier.
Since Luka members apply a class C standard for the airtightness of the air transport route, the fittings must also comply with this class. Fittings included in the LAR comply with the assembly instructions in accordance with NEN-EN 1505 to 1507 and have an airtightness of at least class C, in accordance with NEN-EN 1751, 13180 or 15727.
