Annex 10 - Appendix 2 Methodology for the assessment of AES
              For the purposes of assessing the AES, the approval authority shall verify at least whether the requirement laid down in this Appendix are fulfilled.

              1. The increase of emissions induced by the AES shall be kept at the lowest possible level:

                  (a) The increase of total emissions when using an AES shall be kept at the lowest possible level throughout the normal use and life of the vehicles;

                  (b) Whenever a technology or design that would allow for improved emission control is available on the market at the time of the AES preliminary assessment it shall be used with no unjustified modulation.

              2. When used to justify an AES, the risk of sudden and
