BS EN 1158:1997 – Door co-ordinator devices

BS EN 1158:1997 – Door co-ordinator devices

This European standard specifies requirements for both separately mounted devices and mechanisms incorporated in door closers. There are additional requirements for devices for use on fire/smoke door assemblies. 
BS EN 1158:1997 classifies door furniture by using a 6-digit coding system.
Digit 1 – Category of use
Only one category is identified:
Grade 3: for all internal and external doors for use by the public, and others, with little incentive to take care, i.e. where there is some chance of misuse of the door
Digit 2 – Number of test cycles
Two test durations are identified:
Grade 5: 50,000 test cycles, for all other door coordinator devices
Grade 8: 500,000 test cycles, for door coordinator devices incorporated in, or for use in conjunction with, automatic swing door operators, and for devices incorporated in a door closer
Digit 3 – Test door mass/size
Five door mass grades and related coordinator sizes are identified according to table 1 of this European standard.
Door Co-ordinator Size Test Door Leaf Mass Recommended door leaf width max. mm Distance between hinge centrelines max. mm
3 60 950 1900
4 80 1100 2200
5 100 1250 2500
6 120 1400 2800
7 160 1600 3200



Digit 4 – Fire resistance
Two grades of fire resistance are identified for door coordinator devices manufactured to this European standard:
Grade 0: not suitable for use on fire/smoke door assemblies
Grade 1: suitable for use on fire/smoke door assemblies, subject to satisfactory assessment of the contribution of the door coordinator device to the fire resistance of specified fire/smoke door assemblies

Digit 5 – Safety
All door coordinator devices are required to satisfy the essential requirement of safety in use. Therefore, only grade 1 is identified.
Digit 6 – Corrosion resistance
Five grades of corrosion resistance are identified in accordance with BS EN 1670:2007
Grade 0: no defined corrosion resistance
Grade 1: mild resistance
Grade 2: moderate resistance
Grade 3: high resistance
Grade 4: very high resistance
