Figure 6-2: Equipment for sampling the gases and measuring their volume6.5.3.2. A connecting tube between the device and the exhaust gas sampling system. Thistube, and the device shall be made of stainless steel, or of some other material, whichdoes not affect the composition of the gases collected, and which withstands thetemperature of these gases.6.5.3.3. A heat exchanger capable of limiting the temperature variation of the diluted gases inthe pump intake to ± 5 °C throughout the test. This exchanger shall be equipped witha preheating system able to bring the exchanger to its operating temperature (with thetolerance of ± 5 °C) before the test begins.6.5.3.4. A positive displacement pump to draw in the diluted exhaust mixture. This pump isequipped with a motor having several strictly controlled uniform speeds. The pumpcapacity shall be large enough to ensure the intake of the exhaust gases. A deviceusing a critical flow venture (CFV) may also be used.6.5.3.5. A device (T) to allow continuous recording of the temperature of the diluted exhaustmixture entering the pump.6.5.3.6. Two gauges; the first to ensure the pressure depression of the dilute exhaust mixtureentering the pump, relative to atmospheric pressure, the other to measure thedynamic pressure variation of the positive displacement pump.6.5.3.7. A probe located near to, but outside the gas-collecting device, to collect, through apump, a filter and a flow meter, samples of the dilution air stream, at constant flowrates throughout the test.
6.5.3.8. A sample probe pointed upstream into the dilute exhaust mixture flow, upstream ofthe positive displacement pump to collect, through a pump, a filter and a flow meter,samples of the dilute exhaust mixture, at constant flow rates, throughout the test.The minimum sample flow rate in the two sampling devices described above and inparagraph 6.5.3.7. shall be at least 150 litre/hour.6.5.3.9. Three way valves on the sampling system described in paragraph 6.5.3.7. andparagraph 6.5.3.8. to direct the samples either to their respective bags or to theoutside throughout the test.6.5.3.10. Gas-tight collection bags6.5.3.10.1. For dilution air and dilute exhaust mixture of sufficient capacity so as not to impedenormal sample flow and which will not change the nature of the pollutantsconcerned.6.5.3.10.2. The bags shall have an automatic self-locking device and shall be easily and tightlyfastened either to the sampling system or the analysing system at the end of the test.6.5.3.11. A revolution counter to count the revolutions of the positive displacement pumpthroughout the test.Note 2Note 3Note 4Good care shall be taken on the connecting method and the material or configurationof the connecting parts because there is a possibility that each section (e.g. theadapter and the coupler) of the sampling system becomes very hot. If themeasurement cannot be performed normally due to heat-damages of the samplingsystem, an auxiliary cooling device may be used as long as the exhaust gases are notaffected.Open type devices have risks of incomplete gas collection and gas leakage into thetest cell. It is necessary to make sure there is no leakage throughout the samplingperiod.If a constant CVS flow rate is used throughout the test cycle that includes low andhigh speeds all in one (i.e. part 1, 2 and 3 cycles) special attention should be paidbecause of higher risk of water condensation in high speed range.6.5.4. Driving schedules6.5.4.1. Test cyclesTest cycles (vehicle speed patterns), for the Type I test consists of up to three partsthat are shown in annex 5. Depending on the vehicle class (see paragraph 6.3.) thefollowing test cycle parts have to be run:Class 1:Class 2:Subclass 2-1:Subclass 2-2:part 1, reduced speed in cold condition, followedby part 1 reduced speed in hot condition.part 1, reduced speed in cold condition, followedby part 1 reduced speed in hot condition.part 1 in cold condition, followed by part 2 in hotcondition.
