11.2 Certification
11.2.1 The certification procedures are detailed in Regulation (EC) 631/2009 (22nd July
2009).
11.2.2 The upper legform shall be certified before the test programme.
11.2.3 The foam sheet 2 from which the pieces of foam shall be taken shall be certified before
the test programme.
11.2.4 The upper legform shall be re-certified after a maximum of 20 impacts.
11.2.5 The upper legform shall be re-certified at least once every 12 months regardless of the
number of impacts it has undergone.
11.2.6 If the upper legform exceeds any of its CACs then it shall be re-certified
11.3 Bumper Lead
This is defined as the horizontal distance between the Bonnet Leading Edge Reference Line and
the Upper Bumper Reference Line. The bumper lead may vary across the front of the car;
therefore, the bumper lead must be measured separately at all selected bonnet leading edge
impact points.
11.3.1 Position a vertical straight edge in contact with the Upper Bumper Reference Line
positioned longitudinally to align with the Bonnet Leading Edge impact point.
11.3.2 Measure the horizontal longitudinal distance from the Bonnet Leading Edge Reference
Line to the vertical straight edge. This is the bumper lead at that point. Alternatively a
3D measuring arm can be used to establish this distance. Record the Bumper Lead for
each impact point.
11.4 Bonnet Leading Edge Height
This is defined simply as the vertical height above the ground of the Bonnet Leading Edge
Reference Line. This line follows the contours of the bonnet and its height may vary across the
front of the car, therefore, the bonnet leading edge height must be measured separately at all
