1.4. Determining the aerodynamic free opening area in accordance withEN 12101- 2, Annex BEN 12101-2 requires the specification of the aerodynamic free opening area for smoke extraction from the buildingfor each NSHEV in the roof or facade.The aerodynamic free area A ais calculated by multiplying the clear geometric area of the NSHEV with the coefficientof discharge. The coefficient of discharge Cv (with side wind influence) or Cv0 (without side wind influence)is determined by the notified test centre while testing the NSHEV.1.5. Summary: Basic requirements for D+H Euro-SHEVsIn summary, the following are the basic requirements for a D+H NSHEV in accordance with EN 12101-2:• Drive and window are a single unit• No replacement with non-D+H products• Opening time ≤ 60 seconds• Only tested and certified components are usedIf an NSHEV deviates from the values given in the test and certification reports, the certificate becomes invalid.16Section A
2 The path to the CE marking and to the EC certificate ofconformity for NSHEVsThe harmonised standards of the EN 12101 series of standards generally require implementation of initial typetesting (see Section 2.1) and an initial inspection (see Section 2.2). Only if both tests have been passed successfullymay the manufacturer – upon receipt of the EC certificate of conformity – affix the type plate with the CEmarking (see Section 2.4).Initial type testing is commissioned by a manufacturer from a notified test centre, e.g. for electromotive drives.Initial type testing checks whether the NSHEV exhibits the performance classes (see Section 1.3) specified by themanufacturer.The results of initial type testing are the test and classification reports. Whereas only the tests actually performedand the results are documented in the test reports, in the classification reports these test reports are extended tocover NSHEVs of the same product family and the NSHEVs are classified by performance classes.An application is then made to a notified test centre for an EC certificate of conformity. The manufacturer ofNSHEVs for smoke extraction must establish factory production control and create a product-specific quality plan(see Section 2.2).After the factory inspection has been performed by the notified test centre, the EC certificate of conformity isissued, on the basis of which the type plate may be affixed with the CE marking.EN 12101 provides that all NSHEVs brought into circulation after 1 September 2006 must be CE-certified.The following consequences arise for window manufacturer and/or window and facade manufacturers (hereafterreferred to collectively as window manufacturer): they may only continue to use systems that conform to therequirements and are tested and marked. Window manufacturer must therefore now choose one of two options:a. In-house manufacturer certificationThe window manufacturer must commission manufacturer certification from a notified body in accordance withEN 12101-2. The centre then performs a factory inspection of the window manufacturer. Factory productioncontrol must be guaranteed and a product-specific quality plan must be submitted. Operation will continue tobe monitored by the notified centre.The following problems arise in this case: Most window manufacturer do not have the expertise to secure thenecessary certification in the short term. In addition, the internal expenditure and the costs of the process aresignificant, in particular for SMEs.b. External procurement of complete NSHEVsIn this case, the window manufacturer purchases complete NSHEVs (i.e. window element including openingmechanism) from a certified manufacturer. As the company is not authorised to produce the window elementsitself, the added value for the user is reduced. The consequences for the company are limitation of its core competenciesand profit setbacks.Section A17
