Measurable Quality according to RAL Regulations
Since 2012, the stricter requirements of the RAL guideline RAL-GZ 607/9 have been used to assess the safety and quality of window and door fittings. This guideline refers directly to DIN EN 13126, with part three (DIN EN 13126-3) covering operating handles, including window handles. (DIN stands for German Industry Standard, EN for European Standard).
The RAL-GZ 607/9 guideline sets new requirements for handle fittings and their protective effects. According to this guideline, window handles without protective features must meet the durability class 3/180. This means they must withstand at least 10,000 cycles in tilt-and-turn mode and have a corrosion resistance of class 2 or higher to receive the RAL quality mark.
For optimal burglary protection, the requirements of the European standard series EN 1627-1630 also apply to window handles. According to these, the handle must withstand a force of at least 100 Nm.
Additionally, RAL-GZ 607/9 sets requirements for the locking mechanism of the product. The European class 1, with a value of only 35 Nm, is no longer included in the RAL guideline, as this level has proven insufficient in resisting burglary attempts.
