Time for CE mark
Declared properties of window joinery products in relation to the requirements of Technical Approval – B Mark – from the perspective of the Harmonised Standard they have one class of exploitation properties – rainwater-proof class 4A /150 Pa/. Speed pressure of the wind in the first wind-exposure zone In Poland equals Vk = 250 Pa. Declared properties of window joinery products in relation to B mark do not guarantee that the product whose exploitation properties make it work properly in a building place /building, kind of ground, exposure-zone/. Only the products with the CE mark with the declaration of compatibility in relation to the PN-EN 14351-1 standard guarantee reliability. In the case of VEKA we confirm it by examining mechanical properties and the safety of using.
