windows, shutters, building hardware and curtain walling”, the secretariat of which is held by AFNOR.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by February 2021, and conflicting national standards
shall be withdrawn at the latest by February 2021.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 12046-1:2003.
This document is one of a series of standards for windows.

North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the
United Kingdom.
1 Scope
This document specifies the test method for determining the force required when engaging or releasing
the hardware of a window and when commencing the movement of a casement or sash, in both opening
and closing directions.
This document is applicable to all types of openable windows where the movement is a manual
operation.
This document is applicable to products of any frame material.

3.1
manual operating forces
manual operating forces indicate the force needed to manual operate windows
3.2
linear motion
movement of casement, sash or hardware in a straight line when acted upon by an operating force; also
movement through an arc of which the radius is large in proportion to the length of the arc
3.3
rotary motion
movement, usually of hardware but also applicable to a casement or sash, in a circular path when acted
upon by an operating torque, e.g. the turning action of the bow of a key
3.4
sash weight
weight of the opening or closing sash including its infill (e.g. glazing)
4 Principle of test
The principle consists of measuring the minimum static force or torque required:
— to release or lock the hardware (locks or handles);
— to commence opening of the casement or sash;
— to continue opening/ closing of the sash (in the case o
