Categories and number of cycles of self-closing fire curtains
According to EN 16034
The issue of self-closing cycling is covered in EN 16034: Pedestrian doorsets, industrial, commercial, garage doors and openable windows - Product standard, performance characteristics - Fire resisting and / or smoke control characteristics. Specifically, the product characteristic 'Durability of self-closing against degradation'. This characteristic is ensured by a cycling test, where a total of 6 classes are defined with the codes from 0 to 5. The frequency of use as well as the approximate number of cycles should be proposed by the fire-engineer in the design of the fire protection system.
The Category of use, the number of test cycles to be carried out in order to assign a use category for the self-closing class is given in the following table:
Category of use | Cycles |
---|---|
C5 | ≥ 200 000 |
C4 | ≥ 100 000 |
C3 | ≥ 50 000 |
C2 | ≥ 10 000 |
C1 | ≥ 500 |
C0 | 1 to 499 |
