polyethylene film

Normative reference: EN 13206:2001

Film duration: determined following the procedure set forth by the normative reference EN13206, exposing plastic film in suitable devices equipped with specific lamps (which emit a radiation similar to that of the sun).
To determine film duration, the adopted criterion only considers material degradation obtained in a laboratory through accelerated artificial ageing (Weather-o-meter or Wom).
The duration of a covering material is proportional to the period of exposure to the artificial ageing beyond which mechanical properties are considered no longer efficient.
film classification based on accelerated artificial ageing
Film class Duration (hours)
N ≥ 400
A ≥ 1700
B ≥ 3200
C ≥ 4600
D ≥ 6000
E ≥ 7300
