BS EN 1154:1997 classifies door closers by using a 6 digit coding system.
1. Category of use
Two categories are defined.

2.Number of test cycles
only one categories are is identified.
Grade 8: 500,000 cycles

Where a door closer provides a range of power sizes both the minimum and maximum shall be identified. *Door size/mass in accordance with BS EN 1154:1997
Two categories are defined.
Grade 0 : Not suitable for use on fire/smoke door assemblies
Grade 1:Suitable for use on fire/smoke door assemblies, subject to satisfactory testing and assessment(See BS EN 1634 Part1: 2000)

Grade 0 : No defiined resistance.
Grade 1 : mild resistance
Grade 2 : moderate resistance
Grade 3 : high resistace
Grade 4 : very high resistance
BS EN 1155:1997 -The European Standard for the performance of electrically powered hold open devices for swing doors.
This standard again provides details on product types, classification by use,test cycles,door mass, corrosion resistance, as well as definitions, product performance requirements, test appartus, test mathods and marking of products.
BS EN 1155:1997 classifies products using the same 6 digit coding system as outlined in BS EN 1154:1997. The only difference being box 3 where BS EN 1154 refers to durability, BS EN 1155 refers to hold open power size.
