EN13049Windows - Soft and heavy body impact - Test method, safety requirements and classification


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:

  • The centre of the infill
  • The corner of the infill
  • The mid-point of the longest edge



    Guidance on appropriate levels of performance for use in the UK are given in CWCT TN75. The following classes are recognised across Europe:

    ClassAssociated drop height
    1200 mm
    2300 mm
    3450 mm
    4700 mm
    5950 mm


    CE Marking

    UK Regulations give requirements for barriers to prevent falls from height but there is no impact requirement:
