Impact resistance
Impact resistance of Ecophon products is tested according to EN 13964:2014 (ceiling products) and DIN 18032-3 (wall panels).Both methods feature a predefined ball being shot at the product. However, the ball characteristics, applied speed as well as classification system differs depending on the standard. |
Suspended ceilings are tested and classified according to the table below:
Class | Impact velocity (m/s) | Suitable application area |
1A | 16,5 +/- 0,8 | High velocity sport halls such as hand ball or tennis courts. |
2A | 8,0 +/- 0,5 | Where low energy ball games take place such as volley ball or soft ball |
3A | 4,0 +/- 0,5 | Where low levels of impact resistance is needed such as corridors in schools or day care centres. |
DIN18032-3 only features one level with set requirements that the product must fulfil in order to pass.
