Appendix 2 MEASUREMENT OF SMOKE OPACITY

1. INTRODUCTION U.K.

1.1. This Appendix describes the requirements for measuring the opacity of exhaust emissions. U.K.

2. SYMBOL OF THE CORRECTED ABSORPTION COEFFICIENT U.K.

2.1. A symbol of the corrected absorption coefficient shall be affixed to every vehicle conforming to a vehicle type to which this test applies. The symbol shall be a rectangle surrounding a figure expressing in m^–1 the corrected absorption coefficient obtained, at the time of approval, from the test under free acceleration. The test method is described in section 4. U.K.

2.2. The symbol shall be clearly legible and indelible. It shall be fixed in a conspicuous and readily accessible place, the location of which shall be specified in the Addendum to the type-approval certificate shown in Appendix 4 to Annex I. U.K.

2.3.

Figure IV.2.1 gives an example of the symbol. U.K.

Figure IV.2.1

The above symbol shows that the corrected absorption coefficient is 1,30 m^–1. U.K.

3. SPECIFICATIONS AND TESTS U.K.
