Common use of Test sequence Clause in Contracts

Test sequence. The test sequence shall be started. The test shall be performed in the order of the measuring points 1 to 8 of paragraph 3.6. 1. During each mode of the test cycle after the initial transition period, the specified speed shall be held to within ± 1% of rated speed or ± 3min-1 whichever is greater except for low idle which shall be within the tolerances declared by the manufacturer. The specified torque shall be held so that the average over the period during which the measurements are being taken is within ± 2% of the maximum torque at the test speed. For each measuring point a minimum time of ten minutes is necessary. If for the testing of an engine longer sampling times are required for reasons of obtaining sufficient particulate mass on the measuring filter the test mode period can be extended as necessary. The mode length shall be recorded and reported. The gaseous exhaust emission concentration values shall be measured and recorded during the last three minutes of the mode. The completion of particulate sampling must be coincident with the completion of the gaseous emission measurement and should not commence before engine stabilization as defined by the manufacturer, has been achieved. The fuel temperature shall be measured at the inlet to the fuel injection pump or as specified by the manufacturer, and the location of measurement recorded.

During each mode of the test cycle after the initial transition period, the specified speed shall be held to within ± 1% 1 per cent of rated speed or ± 3min-1 3 min-1 whichever is greater except for low idle which shall be within the tolerances declared by the manufacturer. The specified torque shall be held so that the average over the period during which the measurements are being taken is within ± 2% 2 per cent of the maximum torque at the test speed. For each measuring point a minimum time of ten minutes is necessary. If for the testing of an engine longer sampling times are required for reasons of obtaining sufficient particulate mass on the measuring filter the test mode period can be extended as necessary. The mode length shall be recorded and reported. The gaseous exhaust emission concentration values shall be measured and recorded during the last three minutes of the mode.
