Method of test
A window or external pedestrian door set should be tested to assess impact resistance of the internal and external surfaces. The method of test is described in EN 13049. The tyre impactor described in EN 12600 is used to impact the infill at:
Classification
Guidance on appropriate levels of performance for use in the UK are given in CWCT TN75. The following classes are recognised across Europe:
| Class | Associated drop height |
| 1 | 200 mm |
| 2 | 300 mm |
| 3 | 450 mm |
| 4 | 700 mm |
| 5 | 950 mm |
CE Marking
UK Regulations give requirements for barriers to prevent falls from height but there is no impact requirement:
| Location | npd allowed |
| England and Wales | Probably |
| Scotland | Probably |
| Northern Ireland | Probably |
Note that Specifiers may still require CE marking.
