3 Terms and definitions

For the purposes of this document, the terms and definitions given in GB 11551, GB 15086 and GB 38031 and the following apply.

3.1 door: a hinged or sliding door on the side or rear of the vehicle, opened and closed to let occupants in and out. Note: folding doors, roller doors and simple doors that are easy to fit and remove are excluded. [Source: GB 15086-2013, 2.1, modified]

Note 1: when the door lock is engaged it restrains the door, and the door can be opened by operating the door handle. Note 2: unlatching is either electrical, where the lock is released by an electrically driven mechanism, or mechanical, where it is released by a mechanical mechanism only.

3.4 outer door handle: a handle-like operating mechanism near the door or door frame for unlatching the door lock from outside the vehicle. Note: according to its connection to the door lock, it is either an electrically unlatched or a mechanically unlatched outer door handle.

3.5 inner door handle: an operating mechanism near the door or door frame for unlatching the door lock from inside the vehicle. Note: according to its connection to the door lock, it is either an electrically unlatched inner door handle (including the electronic button type) or a mechanically unlatched inner door handle.
