Textual Amendments

F1 Substituted by Commission Directive 98/12/EC of 27 January 1998 adapting to technical progress Council Directive 71/320/EEC on the approximation of the laws of the Member States relating to the braking devices of certain categories of motor vehicles and their trailers (Text with EEA relevance).

A. Compressed-air braking systems U.K.

2. CAPACITY OF ENERGY SOURCES U.K.

2.3. Conditions of measurement U.K.

2.3.1. In all cases the speed of the compressor shall be that obtained when the engine is running at the speed corresponding to its maximum power or at the speed allowed by the governor. U.K.

2.3.2. The auxiliary equipment reservoirs shall be isolated during the tests for determining the periods T ₁ and T ₂ . U.K.

2.3.3. On motor vehicles constructed to tow trailers, the trailer shall be represented by a reservoir whose maximum relative pressure p (expressed in bars) is that which can be supplied through the feed circuit of the towing vehicle and whose volume V (expressed in litres) is given by the formula p × V = 20 R (R being the permissible maximum load, expressed in metric tonnes, on the axles of the trailer or semi-trailer).] U.K.
