Emergency Exit Doors Constructed According to The EN 1125

BS EN1125 Panic Exit Devices

It is desirable that doors at final exit in public buildings,places of intertainment, shops etc should be fitted with panic devices operated by a horizontal bar or touch bar. the emphasis for products coverd by this standard on safe exit rather than security.

Providing details on product types, classification by use, test cycles, door mass, corrosion resistance as well as defiinition, product performance requirements, test apparatus, test methods and marketing products.

 

The main purpose of the performance requirements of this standard is to give safe and effective escape through a doorway with minimum effort and without prior knoeledge of the device i.e for locked doors on escape routes where panic situation can be for seen.

 

BS EN 1125 applies to – Type Push Bar panic Bolts & Type B Touch Bar Panic Bolts

 

BS EN 1125 Classifies panic exit devices by using a 9 digit coding system, each digit referring to a particular feature of the product measured against the standards performance requirement.  
 

1.Category of use
Only one category is identified.

Grade 3 : Hight frequency of use by people with little incentive to a careful appliacation. where accidents or misuse are possible

 

2.Durability

Two categories are defined.

 
Grade 6 : 100,000 tested cycles

Grade 7 : 200,000 tested cycles
 

3.Test Door Mass

Two categories are defined.

Grade 5 : up to 100kg
Grade 6 : up to 200kg

 

4.Fire Resistance

Two grades of fires resistance are identified:

Grade 0 : Not approved for use on fire/smoke doors

Grade 1 : Suitable for use on fire/smoke door assemblies subject to satifactory assessment of the contribution of the panic/emergency device to the fire resistance of specified fire/smoke door assemblies.

5.Safety

All panic and exit device have a critical safety function therefore only grade 1 is identified .
 

6.Corrosion resistance

Two grades of corrosion resistance are identified according to EN 1670.

 

Grade 3 : High corrosion resistance

Grade 4 : Very high corrosion resistance
 

7.Security
Only one category of security is identified grade 2:

Panic devices are primarily for the operation of a door from the inside. Safety consideration will always be given over security.

 

8: Projection of device 

Two categories are identified.

Grade 1: projection up to 150mm(standard projection)

Grade 2: projection up to 100mm(low projection)

 

9: Type of device 

Two categories are identified.

Type A : push bar operations

Type B : touch bar operations

 

 

BS EN 179 Emergency Exit Devices

This standard covers devices to be used in emergency situations where people are familiar with the emergency exit and its hardware and therefore a panic situation is most unlikely to devlop.lever handle operated escape locks or push padsmay therefore be use.

BS EN 179 applies to - TypeA lever handle operated emergency devices- Type B push pad operated emergency device.

IBS EN 179 classifies emergency exit devices by using a d digit coding system, each digit refering to a particular feature of the product measured against the standards performance requirement.

The particular features in BS EN 179 are identical to BS EN 1125, with two diffrences affecting digit 7 - security and digit 9 - type of device.

Digit 7-Security 

Products covered by BS EN 179 have 3 identified catagories and have the opportunites of greater security than devices covered by BS EN 1125. This is because BS EN 179 devices are subject to testing with doors under greater pressure.Three catagories are defined.

Grade 2:1000N

Grade 3:2000N

Grade 4:3000N

Digit 9-Type of device 

Two categories are identified.

Type A : lever handle operations

Type B : push pad operations

 

CE Marking

CE marking is the easiest and safest route to providing compliance with the latest UK Construction Products Regulations for hardware used on fire,smoke and escape doors.

C.E. marking indicates that the product has been 3rd party performance/fire tested where application and is produced in a factory which has satisfactory production control systems. All of these have to be assessed by an authorised certification organisation.
