Security and standards
• F1 Infill corners
Load is to be applied to each infill corner.
• F2 Leaf/sash corners
Load is applied to the corners of the leaf/sash
if the next locking point is more than 350 mm
away from the corner.
• F3 Locking points
Each locking point is loaded to F3. If two locking
points are less than 200 mm apart, the load is
applied midway between them.
Locking points are all connecon points between
window and leaf/sash frames, including hinges.
• F3.a Locking points
(only for resistance class RC1N)
Load F3.a is applied in conjuncon with load F3
on the flat of the test specimen (reproducibility
of an aack using small lever tools).
The load is applied against the locking direcon
in a way which increases the airgap.
