According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following

Introduction
Hinges suitable for side-hanging use are usually strong enough for top-hanging applications with hinged elements
of the same mass However the load bearing and wearing surfaces are totally different for the two types of
application It is intended to develop test methods for testing hinges in the top-hanging mode which will make it
possible to grade hinges for top-hanging applications more precisely When hinges are used in top-hanging
applications it is important that all aspects of the hinge should be considered, e.g it may be necessary to take
action to prevent loose pins from falling out
In terms of the Constructive Products Directive (89/106/EEC), the essential requirements of this European
Standard are to allow self closing when used on fire/smoke compartmentation doors fitted with door closing
devices
Trang 61 Scope
This European Standard specifies requirements for single-axis hinges, of lift-off or fixed pin type, for use on access
windows and doors Such windows and doors may or may not be fitted also with door closing devices It includes
tests for static loads, shear strength and allowable wear during durability cycling for the following hinges:
a) mounted on the edge of the door leaf or window sash and opening in one direction only;
b) whose axis of rotation is within 30 mm of an edge of the movable element for a door leaf mass of up to 160 kg;
c) whose axis of rotation is within 30 mm of the edge for a window sash with a mass up to 60 kg
This European Standard classifies hinges for four categories of use (see annex A) and also specifies the maximum
permissible torque arising from frictional resistance generated within the hinge during endurance testing
Corrosion protection requirements are specified for those hinges which are not intended to be protected after fitting
There are no restrictions on the materials or the methods of fabrication used providing the hinge conforms to the
requirements relevant to its application
The suitability of single axis hinges for use on fire/smoke compartmentation door assemblies is determined by
performance tests conducted in addition to the performance tests required by this European Standard Annex B
indicates additional requirements for these products
This European Standard does not apply to hinges incorporating spring-assisted door-closing mechanisms Door
closers incorporating door co-ordinator devices (with or without electrically powered hold-open devices) are
covered by EN 1158
Although the fastenings used to fix hinges to window assemblies and door assemblies are not covered by this
European Standard, if the type of fastening to be used is supplied or specified by the manufacturer, such
fastenings are used for the tests
NOTE Performance standards for complete windows and door assemblies (in the course of preparation by CEN/TC
33/WG 1 and TC 33/WG 2) will ensure that the fastenings used to fix the hinge are adequate for their intended duty
