A power-operated door is such that it is likely to injure or trap a person, eg by excessive opening or closing force, or damage or deterioration (Note 1).

Test bar dimensions:

Section of height 60mm, width 30mm with corners radiused to 5mm and tapered at one end over a length of 300mm from a thickness of 30mm to a thickness of 5mm (Figure 5-1-1). Surface to be smooth but shall not be treated with polish or lubricated.

Note 1

A power-operated door may be deemed acceptable in terms of potential injury or entrapment of a person due to excessive closing force if:

a) the door is located at the left-front of the vehicle within the driver’s clear view from his seat (without using mirrors or CCTV), and is opened and closed by means of a driver-operated control, or
