Paragraph 6.4.2.1 General

For the purpose of measuring the noise emitted by lawnmowers when stationary and in motion, six measuring points shall be used, i.e. points 2, 4, 6, 8, 10 and 12. When measurements are taken for stationary mowers, the centre of the hemisphere shall coincide with the projection of the geometric centre of the lawnmower to the ground, pointing from measuring point 1 towards point 5. For moving measurements, the displacement axis shall pass through the positions of measuring points 1 and 5 (See Figures 1 and 2).
