Up-to-date lists and bibliographical references concerning such nationalstandards may be obtained on application to the CEN Management Centre or to any CEN member.This European Standard exists in three official versions (English, French, German). A version in any other language made by translationunder the responsibility of a CEN member into its own language and notified to the CEN Management Centre has the same status as theofficial versions.CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland,France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal,Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.EUROPEAN COMMITTEE FOR STANDARDIZATIONCOMITÉ EUROPÉEN DE NORMALISATIONEUROPÄISCHES KOMITEE FÜR NORMUNGManagement Centre: rue de Stassart, 36

For spring loaded systems, 1,5 FM may be reached for locking in the fully extended or retracted position. NOTE 2
An internal blind belongs to Class 2 if both the operations of moving the curtain and tilting the slats or louvres belong to Class 2. Otherwise the internal blind is Class 1. a
Operation mechanism shall also fulfil the requirements in Clause 5. b
One direction movement and endless movement of the operating mechanism. c
Monocommand.
5 Design of the operating mechanism −−−− Diagrams HPV ("human pull value") 5.1 General Geometrical characteristics of operating mechanisms taking into account the comfort factor. 5.2 Performance requirement 5.2.1 Gear operation Gear with crank or winch handle shall have:  a handle R of length less or equal to 0,20 m (R ≤ 0,20 m);  a reduction ratio r of the gear less than 1:10 (average or mean reduction ratio when, for the same gear, several reductions exist). NOTE A reduction ratio of 1:10 means it is necessary to make ten turns of the crank to achieve one rotation of the roller tube or axle. 5.2.2 Tape, cord or chain operation Operating mechanisms shall have minimal dimensions as given in the HPV diagrams (see Figures 1 and 2).

The diameter calculated can be tested against the diagram at Figure 1 to determine the acceptability relative to the operating effort. The point obtained from dHPV and the measured effort shall be located in area 1 of the Figure 1 diagram.

Figure 3 — Illustration of the six possibilities of forced operation 6.1.2.3 Reversed operation Reversed operations are only applicable to roller internal blinds or to products using a rolling mechanism for extension or retraction. For these products, operation in situation a1 or b2 illustrated in Figure 3 is a reversed operation when the movement in the opposite direction is possible with an effort less than the limit of the class of operation. If the movement is not possible, it is a forced operation. SIST EN 13120:2009

For power operated operations, the effort to be applied is the one produced by the motor.
NOTE There are no performance classes. 7 Mechanical endurance (repeated operation cycles) 7.1 General Ability of the internal blind to withstand a number of operating cycles corresponding to a given usage:  the curtain: one cycle corresponds to a complete operation of curtain extension and retraction including the rest times;  the slats/louvres: one tilt cycle is defined as a complete movement of the pivoting mechanism, moving the slats or louvres from one extreme position to the other and then back again. 7.2 Determination Shall be in accordance with the test methods specified in EN 14201. 7.3 Performance requirement 7.3.1 General After carrying out the cycles relating to the appropriate endurance class, the following requirements shall be fulfilled. 7.3.2 Manual operation  The value of operating effort shall be maintained within the limit of the initial class.  Appearance criteria shall be fulfilled: there shall not be visible defects other than those detailed in Clause 12.
