Shrinkage after Ageing Impact Resistance |
ISO 8256 | Minimum 50% of the value before artificial ageing | 23+2ºC da |
Water Tightness Test | TS EN 607 | No deformation | Water is circulated at 50+2ºC for 15 min, at 15+2ºC for 10 min. Water flow rate must be 18 L/min. |
For necessary tests, a system is engendered with joining rain gutters and fittings.
