Industry, such standards will eventually be put in place. In Europe High Performance Doors must
meet the EN 13241-1 classification. Chart 2-1 differentiates the different class and criteria were
applicable.

2.2.3. Description of Criteria
The follow section gives a brief overview on the individual criteria’s of the EN Standards and how
to decipher the results.
Water permeability
o
Test that determines the water permeability and determines at what wind pressure the
door remains water tight
Example:
Class 1 = Water tight up to 30 Pa (.63psf) of pressure. At higher pressure,
water enters through the door. Refer to Chart 2-1 for the other Class pressure ratings.
Wind Load (resistance)
o
Test that determines to what wind pressure, in Pascal, the door resists in the closed
position.
Example:
Class 1 = the door resists in the closed position 300 Pa (6.3psf) of
pressure. Refer to Chart 2-1 for the other Class pressure ratings.
Wind permeability
o
The quantity of air, in m³/h/m² (ft³/m/ft²), which passes through the door, measured
pressure of 50 Pa (1psf).
Example:
Class 1 = a loss through the door of 24 m³ (14.13 ft³) of air per hour and m²
(ft²) of door.
144 m³/h (84.76ft³/m) of air will pass through a Class 1 door of 6 m²
(64.5ft²) in size.
Safety during opening
o
Test to check if the door creates no danger in terms of cuts, sliding, pressure, etc…
during operation
Mechanical resistance
o
Control of the mechanical aspect of the door.
Unintended movements
o
Control of the forces needed to manually open the door.
Thermal resistance
