1.1 Purpose. Testing the water drainage of vehicle tailgates in the estate (station wagon) and minivan. 1.2 Foreword. The opened tailgate on the estate (station wagon) and minivan generally does not cover the opening area of the body, ensuring that running water cannot permeate the interior. However, any water escaping from the corners of the tailgate or lower panels can impede loadingor unloading. The aim is to prevent rain or water on a wet vehicle from dripping from the tailgate, or to restrict this to within reasonable limits.
