It is based on document TRANS/WP.29/2000/28, not amended (TRANS/WP.29/703, para. 182). However, paragraph 10.6.2.3. was corrected by the secretariat, following a reminder provided by an expert from Japan.

Paragraph 7.4.1.3., amend to read:

" ......

When the abrasive anvil is used, evaluate the front, rear, sides and crown areas of the helmet, selecting within these general areas, sites on the outer surface which are likely to produce the greatest force and/or the greatest impulse where impulse is the integral of force with respect to time over the duration of the impact. Examples of such areas are those having the greatest radius of curvature (i.e. the flattest surface) or areas having more than one type of surface, for example a visor fixing cover plate or a painted shell partially overlaid by a fabric cover.
