3.3.2
chin buckle
device arranged near the chin to adjust the tightness of the strap
3.4

3.5
basic plane of the human head
plane at the level of the center of the external ear openings and the lower edge of the right (or left) eye socket
Note: See plane O-O' in Figure 1.
Key:
1——plane O-O’;
2——the center of the external ear openings;
3——the lower edge of the right (or left) eye socket.

3.7
reference plane of the testing headform
plane on the headform, with a distance (X) above and parallel to the basic plane of the testing headform, where such distance (X) is determined by the headform size
Note: See Figure 2.
3.8
headform size
length of the curve formed by the intersection of the reference plane and the outer surface of the headform, which can be divided into standard headforms in four sizes
Note: See Figure 2.
3.9
protection class
