Mechanical resistance

Standard : NF EN 1886: 2006
Ventilation of buildings - Air handling units - Mechanical performances

Role : Assessment of the resistance capacity of the casing under pressure and in negative pressure

The mechanical resistance to deflection of the casing corresponds to the greatest distortion of the panels under a given pressure or negative pressure, as the difference in terms of distance between a reference plane situated outside the unit in nil pressure and the external surface subjected to the test pressure. The deflection determines the mechanical resistance.

Result:
D1

The air handling units have been assessed at the best performance level for mechanical resistance by TUV Nord.
