Test parameters. Test parameters, as specified in Table A4/1, shall be measured at a constant frequency of 1.0 Hz or higher and recorded and reported in accordance with the requirements of paragraph 10. of Annex 7 at a sampling frequency of 1.0 Hz. If ECU parameters are obtained, these may be obtained at a substantially higher frequency but the recording rate shall be 1.0 Hz. The PEMS analysers, flow-measuring instruments and sensors shall comply with the requirements laid down in Annexes 5 and 6.
