The hand of door for mortise locks is defined as:
if the door is closed and the hinges are visible on the right/left, then the door is right/left hand. The door is therefore hinged on the right/left and according by definition of DIN right/left.
Or: if you grasp the handle with your right hand and latch and deadbolt show to the left, then it is right hand. If you grasp the handle with your left hand latch and deadbolt show to the right, it is a left hand.
Rim locks
The hand of door for rim locks is defined as:
if the door is closed and the hinges are visible on the right/left, then the door is right /left hand. The door is therefore hinged on the right/left and according to the definition DIN “right/left".
In addition to the designation “left” and “right”, it is to be indicated whether the locks are intended for inward or outward opening doors.
Sliding door mortises
The hand of door for sliding door mortises is the same for right and left. Sliding rim door locks different for left and right doors.
