ALsistem has set up a test laboratory which provides top-notch technical support to window manufacturers, designers and builders for their most important and challenging projects.
The laboratory is set up to perform tests on windows of up to 6 metres in size, four-leaf sliding windows and facade modules of up to 5 metres.
The test bench has been approved by a Notified Body in Milan which issues valid test reports for CE marking.

Tests performed in the laboratory

In our laboratory the following environmental tests are performed on windows, sliders and facade modules:
Air permeability (EN 12153): the frame or facade must control the passage of air so as to both protect the indoor spaces and allow for the right amount of ventilation.
Water tightness (EN 13050): the frame or facade must prevent or limit the ingress of rain, both through the fixed components and the parts that can be opened. Where uneven parts are joined together, they must ensure the seal is maintained an that water can be drained away.
Wind resistance (EN12179): the frame or facade must be sturdy enough to resist wind loads.
Calculation of the thermal transmittance value (Uf) using the relative software.

CE Marking

The CE Marking is an essential certification for products in the European Economic Area (EEA) which defines a level playing field for manufacturers through the provision of:
Test methods;
Procedures and evaluation criteria shared across European Union countries.

The CE Marking is mandatory and is the system with which manufacturers of windows, continuous facades, sunshades, industrial and garage doors and gates, and smoke and heat extractors must comply in order to sell their products in the European Union.

The application of the CE Marking indicates, therefore, the suitability of the product for its intended use and guarantees a certain level of performance in relation to said intended use.

Declaration of conformity for windows

The declaration of the conformity of a manufactured window to the harmonised European technical standards (product regulations) must be demonstrated through:
Initial type testing (ITT) which, depending on requirements, entails the performance of theoretical calculations on one or more sample products that are representative of the whole product range in compliance with the relative European product regulations;
Factory production control (FPC) carried out under the responsibility of the manufacturer. It is the responsibility of the manufacturer or its representative to apply the CE Marking to the product, by means of a label affixed to the product, its packaging or the accompanying commercial documents.
The CE Marking replaces any mandatory national markings but not those of a voluntary nature provided they do not conflict with and/or overlay the CE Marking.
