BS EN 13115:2020 pdf free.Windows一Classification of mechanical properties – Racking, torsion and operating forces.
BS EN 13115 1 Scope This document provides a means of classifying the performance of opening windows according to their strength in resisting, where appropriate, racking load, static torsion and their manual operating forces.Special aspects such as those of burglar resistance are not covered.1) 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies.

The specimen shall not suffer such damage or deformation, including breakage or loosening of hardware, joints or weather sealing systems, as would render it unfit for its purpose.4.2 Operating forces Opening windows shall be tested in accordance with EN 12046-1. Tables 1 and 2 list the forces and/or torques to be sustained for the various classes. The highest average value (force/torque) defines the overall classification.4.3 Racking and static torsion 4.3.1 Resistance to racking load AIll types of openable windows shall be tested in accordance with EN 14608. Table 3 lists the forces to be sustained for the various classes.
4.3.2 Resistance to static torsion All types of openable windows excluding sliding windows shall be tested in accordance with EN 14609.Table 3 lists the forces to be sustained for the various classes.4.3.3 Classification for racking and static torsion All types of openable windows excluding sliding windows shall be subjected, separately, to tests for racking, static torsion and operating forces.Sliding windows shall be subjected, separately, to tests for racking and operating forces only.Secondary sashes/casements, only to be opened for cleaning ormaintenance mode of operation shall be tested to 100 N only for racking loads in the case of sliding sashes and for racking loads and static torsion in the case of all other opening casements.BS EN 13115 pdf download.
