# Commission Regulation (EC) No 631/2009 of 22 July 2009 laying down detailed rules for the implementation of Annex I to Regulation (EC) No 78/2009 of the European Parliament and of the Council on the type-approval of motor vehicles with regard to the protection of pedestrians and other vulnerable road users, amending Directive 2007/46/EC and repealing Directives 2003/102/EC and 2005/66/EC, Division

Extent: E+W+S+N.I.

Headform impactor tests shall be to the bonnet top. A minimum of eighteen tests shall be carried out with the headform impactor, six tests each to the middle and the outer thirds of the bonnet top at positions judged to be the most likely to cause injury. Tests shall be to different types of structure, where these vary throughout the area to be assessed.
Among the minimum of eighteen tests, at least twelve tests shall be carried out with the headform impactor within the ‘HPC1000 Zone’ and a minimum of six tests shall be carried out within the ‘HPC2000 Zone’ as set out in point 3.2.1.
The test points shall be located so that the impactor is not expected to impact the bonnet top with a glancing blow and then impact the windscreen or an A-pillar more severely.
The selected test points for the child/small adult headform impactor shall be a minimum of 165 mm apart, a minimum of 82,5 mm inside the defined side reference lines, a minimum of 82,5 mm forwards of the defined bonnet rear reference line.
Each selected test point for the child/small adult headform shall also be a minimum of 165 mm rearwards of the bonnet leading edge reference line, or rearward of a wrap around distance of 1 000 mm, whichever is more rearward at the selected test point, unless no point in the bonnet leading edge test area within 165 mm laterally would, if chosen for an upper legform to bonnet leading edge test, require a kinetic energy of impact of more than 200 J.
These minimum distances are to be set with a flexible tape held tautly along the outer surface of the vehicle. If a number of test positions have been selected and the test area remaining is too small to select another test position while maintaining the minimum spacing between tests, then less than eighteen tests may be performed. The positions tested by the laboratories shall be indicated in the test report.
However, the technical services conducting the tests shall perform as many tests as necessary to guarantee the compliance of the vehicle with the head protection criteria (HPC) limit values of 1 000 for ‘HPC1000 zone’ and 2 000 for ‘HPC2000 zone’, especially in the points near to the borders between the two types of zones.
