Implementation Guide for Standard EN16005 in Power-Operated Sliding Doors

 

1. AIM

The aim of this memorandum is to establish a summarised guide for the implementation of Standard EN16005, Power operated pedestrian doorsets – Safety in use – Requirements and test methods, in the configuration, sale and installation of Manusa's power-operated pedestrian sliding doors.  

 

2. LEGAL AND REGULATORY FRAMEWORK

A power-operated sliding door is a machine and, as such, falls within the scope of application of the Machines Directive. 

Compliance with the directive may be implemented via the application of the harmonised standard EN16005: Power operated pedestrian doorsets – Safety in use – Requirements and test methods.

EN16005 came into force and is harmonised with the Directive since April 2013. The following countries are bound to comply with it: Germany, Austria, Belgium, Denmark, Spain, Finland, France, Greece, Holland, Ireland, Iceland, Italy, Malta, Norway, Portugal, Czech Republic, Sweden, Switzerland and United Kingdom.

After the publication of these standards, the aforementioned countries must revoke the specific regulations they had in force. Specifically, the following standards will disappear: 

  • Germany: DIN 18650 

  • United Kingdom: BS 7036

 

3. OVERVIEW OF MANUSA'S CONFORMITY MEASURES 

The aim of the EN16005 Standard is to increase the safety standards in the use of power-operated pedestrian doorsets. 

To this end, the Standard defines a set of requirements, the most important of which are listed below: 

3.1 Design of the Operator and the Sensors (Standard sections 4.3, 4.4) 

Electrical drives shall fulfil the requirements of EN 60335-2-103 for electrical safety.  

 

 Furthermore, safety related parts of the control system shall comply with EN 13849-1 Performance Level “c”. In the case of doorsets without a break-out function located in emergency exits or escape routes, the opening control systems shall comply with Performance Level “d”. This means that the drive systems shall be reliable and fail-safe (see note).

design of the operator

NOTE: According to EN13849, a performance level “c” means that the probability of failure per hour is less than 3 in 1 million and, for performance level “d”, the probability of failure per hour is less than 1 in 1 million.

3.2 Automatic Activation System (4.5)

The door may be activated by a sensor, a floor mat or by hand (push button, push&go system, etc.). If activated by a sensor, the detection zone should be a minimum of 1 m in front of the plane of the doorset.

In the case of power operated doorsets on escape routes or emergency exits without break-out function, the interior detection zone of the sensor shall be not less than 1.5 meters.

3.3 Avoidance of danger points (4.6)

Danger points are essentially located in edges A and B of the leaf, where there are crushing, shearing, impact and drawing-in hazards. Danger points shall be safeguarded up to a height of 2,5 m above the floor by several means, depending on whether the protection is needed during the opening or the closing cycles.

3.3.1 Protection in the closing cycle (4.6.1, 4.6.2.2)

The following may be used:

     - Sensors

They may be PSPE (by pressure, with contact) or ESPE (without contact).

When a large proportion of the users are elderly, infirm, disabled persons, young children or people with reduced mobility, any contact of the doorset with the user is unacceptable and, therefore, in these cases ESPE sensors shall always be required.

If sensors are used, the area to be protected must be equal to the clear opening width by a minimum width of 200 mm at both sides of the door, which shall be tested using a "CA" reference body:

 

According to the Standard, the traditional protection systems in the closing area by means of one or two photocells are valid (refer to section 4.6.8 regarding ESPE), but the following requirements must be taken into consideration:

a) In order to detect the reference body in the whole area referred to in the previous paragraph, the upper photocell must be located at a height of 600-700 mm and, if only photocells are used, they shall be located at both sides of the door (interior and exterior):

 

 

They may also be combined with AIR-type sensors: for instance, an AIR sensor on one side and a photocell on the other.

b) These devices shall not be used when a large proportion of the users are elderly, children, disabled persons or people with reduced mobility since, potentially, they might not prevent contact on the exterior up to the required height of 2.5 m.

     - “Low energy” movement (4.6.4)

Low energy movement means that the kinetic energy of a doorset in motion shall not exceed 1.69 J. The kinetic energy depends on the mass of the doorset and its maximum speed; therefore, at low energy the speed of the leaves is limited. The maximum static force shall not exceed 67 N.

Additionally, protection may be installed in the closing cycle:

     - Limitation of impact forces (4.6.1, 4.6.7)

In general, limitation solutions for impact forces may be used to prevent crushing or impact hazards.

The Standard details the values of dynamic forces depending on leaf movement and the permissible times. A static closing force up to 150 N is allowed.

When photocell units are used as protection sensors, an impact force limitation system may be used to guard the area above the detection threshold of the reference body, up to the minimum required height of 2.5 m.

3.3.2 Protection in the opening cycle (4.6.2.1)

Protection against crushing, impact, drawing in and shearing during the opening cycle of the leaves may be implemented as follows:

a) Shearing and drawing-in protection:

     - Safety distances

There are two options available as specified in the following figures:

                                                            

  • Option 1: S = 8 mm, Y = 0 mm
  • Option 2: S > 8 mm, Y = 25 mm

 

 

b) Crushing and impact protection:

     - Safety distances

Sufficiently dimensioned safety distances:

     - Limitation of the impact force

It may also be implemented by limiting the impact force. In order to ensure that no additional measures are required, the following safety distance shall also be verified:

The Standard details the values of dynamic forces depending on leaf movement and the permissible times. A static closing force up to 150 N is allowed.

     - Barriers or Guards

Alternatively, for crushing and impact hazards, barriers or guards may be used (for example, fixed double leaves) to prevent access to the movement area during the opening cycle of moving leaves:

     - Sensors

Alternatively, ESPE or PSPE sensors may be installed to reduce the opening speed of the leaves.

If sensors are used, the area to be protected must be equal to the clearance area by a minimum width of 200 mm at both sides of the door. This shall be tested using a standard reference body:

When a large proportion of the users are elderly, infirm, disabled persons, young children or people with reduced mobility, any contact of the leaf with the body of the user is unacceptable. In these cases, applying the safety distances and force limitations will not suffice, and the use of ESPE sensors, barriers or guards shall be required.

     - “Low energy” movement (4.6.4)

Similarly to the opening cycle, low energy movement means that the kinetic energy of a doorset in motion shall not exceed 1.69 J, and the maximum static force shall not exceed 67 N. The kinetic energy depends on the mass of the doorset and its maximum speed; therefore, at low energy the speed of the leaves is limited. This increases opening times.

3.4 Additional requirements for doorsets in escape routes and emergency exits (4.7.2)

As a general rule, if a "locked" mode of operation is available, the mode of operation shall be protected, e.g. by an access code or a key. Optima Selector must be installed safe from malicious or unauthorized interventions.

3.4.1. Doorsets without break-out function:

As we pointed out above, both the opening drive electronics and the interior activation sensors need to comply to EN13849 Performance level “d”, and they shall be configured to activate at a minimum distance of 1.5 meters from the doorset.

The system shall guarantee the following:

- In the case of activation signals, doorsets with a clear opening width of up to 2 meters shall open by at least 80% of the clear opening width within 3 s (Opening time for larger doorset widths shall be calculated proportionally).

- The opening of the doorset shall be guaranteed by a fail-safe system in accordance with Performance Level “d” of EN13849, which shall check the operation of the doorset every 24 hours.

- Any electrical faults preventing normal operation of the doorset shall be detected within 15 s and cause the doorset to automatically open, at the latest after 5 s, and remain in the open position (except when in the security-locked position).

- If the opening process is performed via battery, the system shall monitor the battery to verify that there is sufficient charge to open the door at least once.

3.4.2. Doorsets with break-out function:

In those cases, the requirements are as follows:

- Its is only necessary to install an operator and sensors which comply to EN 13849 Performance Level “c”.

- The total force required to release the break-out function shall not exceed 220 N.

- A pictogram shall be fitted on all doors with a break-out function.

3.5 Testing (5, 4.7.2.3)

According to the Standard, doorsets shall be subjected to operation and durability tests at ambient temperature and at extreme temperatures. Emergency exits shall be subjected to a minimum durability test of 1 million cycles.

3.6 Maintenance (4.2, 5.3)

Doorsets shall undergo routine maintenance to guarantee safety, long-term reliability and efficient operation. Maintenance shall be performed according to the manufacturer's instructions, and the correct operation of the doorset shall be checked with a minimum recommended frequency of one year.
