(UNI EN 13049)
The soft and heavy body impact test verifies the window’s ability to withstand sudden and accidental collision with things or people without posing danger for the user. The test considers the impact of a mass, consisting of a wheel of 50 kg (image 2), falling from a given height onto one side of the sample window in certain specific points, as indicated in regulation UNI EN 13049, and identified as the most critical in relation to the stress inflicted.
The aim is not to verify glass resistance, but to evaluate all interactions between the materials involved, in order to guarantee a safer product for the user. The UNI EN 13049 test regulation contemplates 5 different performance classes, depending on the height of the wheel’s fall. The greater the anticipated height of the fall, the higher the performance of the product. Class 5 is the highest, while class 1 is the minimum compliance level.
Doc Legno window (Item 92) belongs to performance class 5.
