With the increasing popularity of plastic window and door profiles, the demands on the material have also increased in recent years, particularly in terms of load-bearing capacity and durability. Particular importance is attached to shock and impact resistance, which is a decisive criterion for processing, transport, installation and – last but not least – daily use by the house occupants. Proof of quality is an indispensable selling point in competition with international competitors. A large number of standards and test specifications take this into account, but also put manufacturers under pressure. If a manufacturer wants to obtain the RAL quality mark 716/1, the plastic profiles must be tested for shock resistance in cold conditions via impact stress using a falling weight in accordance with DIN EN 477 and fulfil the relevant requirements.

All test parameters are input via the keypad on the touchscreen and can be checked at any time via the display. The fall velocity achieved is displayed on the touchscreen after each test procedure. This allows a reliable statement to be made about the actual impact energy. Recurring test parameter sets can be saved and accessed again at a later date via the touchscreen.
