6. Measurements to be made on the vehicle ...
6.2. The speed curve which will be used in the test procedure described in Appendix 4 must be obtained from the longitudinal accelerometer at the 'B'pillar on the side struck. ... When multi-axial accelerations at a point are to be measured, each acceleration transducer axis should pass within 10 mm of that point, and the centre of seismic mass of each accelerometer should be within 30 mm of that point.
