Technical testing, analysis and consultancy services

Tender description

DVSA is planning to undertake a programme of market surveillance testing to primarily check the emissions performances of vehicles, as well as other type-approval testing on a wide range of vehicles, and vehicle components. The aims of the emissions investigation will be to check that in-service vehicles comply with the relevant emissions standards for their category and for evidence of cycle recognition devices. Attention will be paid to the range of pollutants and any disparities observed under the different test conditions. DVSA is putting in place a testing services framework which is being tendered under the OJEU (Official Journal of the European Union) contract notice number 2017/S 075-145107. DVSA is putting in place a separate framework arrangement to source future Data Analysis and Report Writing Services. From the laboratory results DVSA will require analysis for each vehicle of the emissions profile against the cold NEDC results, to check for the presence of possible cycle recognition strategies, other anomalous emissions characteristics and prohibited defeat devices. The emissions track results will be analysed in the same way to allow a comparison to the legislated emissions limits and, where appropriate, against the laboratory test results. The Real Driving Emissions (RDE) test results should be analysed to establish, where relevant, the conformity factors for NOx and particle number (PN) emissions as defined in RDE legislation as well as to highlight any anomalous emissions characteristics.
