Building hardware - Mechatronic door furniture - Requirements and test methods

1.1   General
This document applies to Mechatronic door furniture (MDF) fitted on the door set which gives the possibility to control the locking and/or release part through an electronic authorization means. This can be operable by credentials (i.e. card, code, biometric).
The MDF according to this document is combined with locks according to EN 12209, EN 14846, prEN 15685 or may be a part of an emergency exit device according to EN 179, EN 1125 or EN 13637.
The MDF may be standalone or linkable to an external control system.
The document would allow classifying the MDF upon several characteristics such as category of use, durability, environmental, security, and type of operating device.
The suitability of the MDF for use on fire or smoke-door assemblies is determined by fire resistance tests conducted in addition to the performance testing specified by this document.
1.2   Exclusions
This document does not cover:
-   mechatronic cylinders according to EN 15684;
-   electromechanical operated locks and striking plates according to EN 14846.

1.1   Allgemeines
Dieses Dokument gilt für an der Tür angebrachte mechatronische Türbeschläge (MDF, en. mechatronic door furniture), die die Möglichkeit eröffnen, den Schließ  und/oder Öffnungsvorgang durch eine elektronische Freigabeberechtigung zu steuern. Das kann durch Berechtigungsnachweise erfolgen (d. h. Karte, Code, biometrisch).
Der diesem Dokument entsprechende MDF wird mit Schlössern nach EN 12209, EN 14846, EN 15685 kombiniert oder kann Teil eines Notausgangverschlusses nach EN 179, EN 1125 oder EN 13637 sein.
Der MDF kann eigenständig ausgeführt sein oder mit einem externen Steuersystem verbunden werden.
Das Dokument würde es ermöglichen, die MDF mittels mehrerer Eigenschaften, wie etwa Gebrauchskategorie, Dauerfunktionstüchtigkeit, Umweltbeständigkeit, Schutz und Typ der Betätigungsvorrichtung zu klassifizieren.
Die Eignung des MDF für die Verwendung an Feuer  oder Rauchschutzeinbauten wird durch Prüfungen des Feuerwiderstands bestimmt, die zusätzlich zu den in diesem Dokument festgelegten Leistungsprüfungen durchgeführt werden.
1.2   Ausnahmen
Dieses Dokument behandelt nicht:
-   mechatronische Schließzylinder nach EN 15684;
-   elektromechanisch betätigte Schlösser und Schließbleche nach EN 14846.

Introduction

The development of building hardware to include electrically and electronic operations and control has

introduced a large number of products on the market.

For locks and door furniture, the range of electrical or electronic components to be fitted to existing

mechanical locks or door furniture to a complete Mechatronic Door Furniture (MDF) has increased.

Also, complete units with lock and door furniture in unique combination to MDF occur frequently.

Typically, MDF is installed directly on the door leaf and includes all functions like operating the follower

of the lock, reading and decoding the credential and power.
Following components and units are covered by this document.

Type A: Handle or knob operated door furniture with electrically operated actuator, reading unit for

credential and power supply to be combined with a mechanical operated lock where the lock meets

EN 12209 or EN 15685.

Type B: Handle or knob operated door furniture with reading unit for credential and power supply to be

combined with electrically operated locks where the lock meets EN 14846.

This document does not cover electrically operated locks or striking plates in combination with an access

control system not fitted on the door.
This document provides the MDF with requirements for:
— category of use to ensure the performance during its normal use;
— durability to ensure good performance during lifetime;
— specification for system management;
— suitability for use on fire resistant/smoke controlled doors;

— environmental resistance for good performance during lifetime in different environmental

conditions;
— security for different types of credentials;
— attack resistance to ensure use on Burglary resistant doors;
— product information to give summary of the performance.

The performance tests incorporated in this document are considered to be reproducible and as such will

provide a consistent and objective assessment of the performance of these devices throughout CEN

Member States.

It is assumed that MDF will conform to the legal regulations i.e. RED – Radio Equipment Directive

2014/53/EU.

On occasion, there could be a need for additional functions within the design of the MDF. Purchasers

should convince themselves that the products are suitable for their intended use. This is particularly

important when the operation of such additional functions is safety-related. Accordingly, this document

includes assessment of such features when they are included in the MDF design.

The grading 1 and 2 for category of use gives the performance aimed for product to the residential market

and grades 3 and 4 focus more on commercial building application see also 7.2.
When the MDF is fitted to the door there shall be no sharp edges.

NOTE This requirement would typically be satisfied by edges that are broken by a chamfer of 0,5 mm

maximum × 45° or by a radius of 0,5 mm minimum.

In the area of rotation of the lever handle or knob, the head of any visible fastening element shall be level

with or below the surface of the backplate or rose after fitting. However, raised head screws may stand

proud of the furniture plate by the domed height of the screw head.

Any fastening element that secures the lever handle or knob to the spindle shall not project above the

surface by more than 1 mm after fitting.

The design of MDF shall ensure that, after fitting, it is not possible for the fingers of a user to be trapped

between lever handle or knob and backplate or rose over the full range of rotation of the lever handle or

knob.

4.2.2 Axial strength of MDF and fixing

The MDF shall resist an axial force F1 indicated in Table 1 for the different grades without breaking any

component.

The MDF shall be operable and have a maximum permanent deformation δ1 indicated in Table 1 at the

reference point after de-loaded the force.
The test shall be done in accordance with 6.2.2.
4.2.3 Requirement for free play

The maximum total movement of all knobs, thumb turns or lever handles mechanically connected to the

MDF shall not exceed the value specified in Table 1.
See Figure 2. (6.2.3)
The test shall be done in accordance with 6.2.3.
4.2.4 Free angular movement or misalignment

Where applicable the free angular movement or misalignment of the MDF shall not exceed the value

specified in Table 1.
The test shall be done in accordance with 6.2.4.
4.2.5 Operating torque
4.2.5.1 Unsprung and spring assisted lever handles

The torque M1 required to return the unsprung or spring assisted lever handle back to its intended “at-

rest” position shall be not greater than the value specified in Table 1.

After the durability test the spring-assisted lever handles only, the torque M2 required to rotate the lever

handle to a minimum angle of 40° from its intended “at-rest” position shall not exceed the value specified

in Table 1.
The test shall be done in accordance with 6.2.5.1.
4.2.5.2 Unsprung knobs

The return torque M3 value for unsprung knobs shall in either direction not be greater than the value

specified in Table 1.
The test shall be done in accordance with 6.2.5.2.
4.2.5.3 Spring loaded lever handles or knobs

For spring loaded handles, knobs or thumb turns, the torque M4 required to rotate the lever handles,

knobs or thumb turn through an angle α of 60° 0°/+5° or through the angle of rotation possible by the

design shall not be more the value specified in Table 1.

After the durability test and after removal of the torque, the lever handle or knob shall return to its

recorded “at-rest” position within angle φ according to the value specified in Table 1.

The test shall be done in accordance with 6.2.5.3.

4.2.6 Rotational torque strength

The MDF shall resist rotational torque M5 specified in Table 1 and shall show no failure of any component

and the lever handles or knobs shall still be operational after the test.

Lever handles or knobs shall not deform permanently more than a distance δ4 according to Table 1 as

measured at the reference point after de-loaded the torque.
The test shall be done in accordance with 6.2.6.
4.2.7 Minimum lever or knob torque transfer
4.2.7.1 Minimum lever torque transfer
The MDF shall be able to transfer the torque specified in Table 1.

If a MDF is equipped with a lever on the outside and this MDF is protected by a mean to prevent damage

in case of excessive torque M6 is applied to the lever, the mean shall be able to transfer a minimum torque

as specified in Table 1.
Compliance is checked by the test methods given in 6.2.7.
