This part of EN 13126 specifies requirements and test methods for durability, strength, security and function of mechanically operated variable geometry stay hinges (with or without a friction system).By means of this European Standard, the user of recognized tested hardware can assume that with correct usage, the variable geometry stay hinges (with or without a friction system) for windows conform to prescribed requirements.NOTE 1This European Standard is applicable to variable geometry stay hinges (with or without a friction system) whether fitted with integral restrictors or not.NOTE 2Balancing stay arms/hinges do not represent a friction system.NOTE 3For the purposes of this European Standard, the friction system is achieved by friction pads or similar.
