INTRODUCTION This Annex lays down the rules for testing and/or checking braking systems and exhaust emissions during a technical roadside inspection. The use of equipment is not mandatory during roadside inspections. However, it will enhance the quality of inspections and, where possible, it is recommended. Items that may only be checked by the use of equipment have been marked with an (E). Where a method of inspection is given as visual, it means that in addition to looking at the items, the inspector should, if appropriate, also handle them, evaluate noise or use any other appropriate means of inspection without the use of equipment. 2.

Exhaust emissions 8.2.1 Petrol engine emissions 8.2.1.1. Exhaust emission control equipment Visual inspection. (a) Emission control equipment fitted by the manufacturer absent or obviously defective. (b) Leaks which could significantly affect emission measurements. 8.2.1.2. Gaseous emissions (E) Measurement using an exhaust gas analyser in accordance with the requirements (7). Alternatively, for vehicles equipped with suitable on-board diagnostic systems, the proper functioning of the emission system can be checked by appropriate reading of the OBD device and checks on the proper functioning of the OBD system in place of emission measurements at engine idle in accordance with the manufacturer’s conditioning recommendations and other requirements (7) and taking account of appropriate tolerances. Alternatively, measurement using remote sensing equipment and confirmed by standard test methods. (a) Either, gaseous emissions exceed the specific levels given by the manufacturer; (b) or, if this information is not available, the CO emissions exceed, 1. for vehicles not controlled by an advanced emission control system, — 4,5 %, or — 3,5 %, according to the date of first registration or use specified in requirements (7) 2. for vehicles controlled by an advanced emission control system, — at engine idle: 0,5 %, — at high idle: 0,3 %, or — at engine idle: 0,3 % (5) — at high idle: 0,2 %, according to the date of first registration or use specified in requirements (7). (c) Lambda outside the range 1 ± 0,03 or not in accordance with the manufacturer’s specification. (d) OBD read out indicating significant malfunction. (e) Remote sensing measurement showing significant non-compliance. 8.2.2 Diesel engine emissions 8.2.2.1. Exhaust emission control equipment Visual inspection. (a) Emission control equipment fitted by the manufacturer absent or obviously defective. (b) Leaks which could significantly affect emission measurements. 8.2.2.2. Opacity (E) (a) Exhaust gas opacity to be measured during free acceleration (no load from idle up to cut-off speed) with gear lever in neutral and clutch engaged. (b) Vehicle preconditioning: 1. Vehicles may be tested without preconditioning although for safety reasons checks should be made that the engine is warm and in a satisfactory mechanical condition. 2. Precondition requirements: (i) Engine shall be fully warm, for instance the engine oil temperature measured by a probe in the oil level dipstick tube to be at least 80 °C, or normal operating temperature if lower, or the engine block temperature measured by the level of infrared radiation to be at least an equivalent temperature. If, owing to vehicle configuration, this measurement is impractical, the establishment of the engine’s normal operating temperature may be made by other means, for example by the operation of the engine cooling fan. (ii) Exhaust system shall be purged by at least three free acceleration cycles or by an equivalent method. (c) Test procedure: 1. Engine and any turbocharger fitted, to be at idle before the start of each free acceleration cycle. For heavy-duty diesels, this means waiting for at least 10 seconds after the release of the throttle. 2. To initiate each free acceleration cycle, the throttle pedal must be fully depressed quickly and continuously (in less than one second) but not violently, so as to obtain maximum delivery from the injection pump. 3. During each free acceleration cycle, the engine shall reach cut-off speed or, for vehicles with automatic transmissions, the speed specified by the manufacturer or if this data is not available then two thirds of the cut-off speed, before the throttle is released. This could be checked, for instance, by monitoring engine speed or by allowing a sufficient time to elapse between initial throttle depression and release, which in the case of vehicles M2, M3, N2 or N3 should be at least two seconds. 4. Vehicles shall only be failed if the arithmetic means of at least the last three free acceleration cycles are in excess of the limit value. This may be calculated by ignoring any measurement that departs significantly from the measured mean, or the result of any other statistical calculation that takes account of the scattering of the measurements. Member States may limit the number of test cycles. 5. To avoid unnecessary testing, Member States may fail vehicles which have measured values significantly in excess of the limit values after less than three free acceleration cycles or after the purging cycles. Equally to avoid unnecessary testing, Member States may pass vehicles which have measured values significantly below the limits after less than three free acceleration cycles or after the purging cycles and taking account of appropriate tolerances. Alternatively, measurement using remote sensing equipment and confirmed by standard test methods. (a) For vehicles registered or put into service for the first time after the date specified in requirements (7), opacity exceeds the level recorded on the manufacturer’s plate on the vehicle; (b) where this information is not available or requirements (7) do not allow the use of reference values, — for naturally aspirated engines: 2,5 m–1, — for turbo-charged engines: 3,0 m–1, or, for vehicles identified in requirements (7) or first registered or put into service for the first time after the date specified in requirements (7), — 1,5 m–1 (6). (c) Remote sensing measurement showing significant non-compliance.
