Revised vehicle emissions and testing requirements bring new challenges for automotive manufacturers
Comparisons of laboratory-based vehicle emissions test results with those from on-road testing show a significant gap between reported and actual fuel consumption and carbon dioxide (CO2) emissions. To address these issues, the Worldwide Harmonized Light Vehicles Test Procedures (WLTP) have been developed by a United Nations technical working group and will take effect in 2017 in the EU plus 10 additional countries. At the same time, the EU has adopted regulations that mandate so-called Real Driving Emissions (RDE) test procedures to more accurately evaluate vehicle performance under real-world conditions.
How TÜV SÜD is working to address the compliance challenge
To streamline the emissions testing process, and to optimally assist automotive manufacturers in coordinating testing for compliance with these new emissions testing requirements, TÜV SÜD has been working with partner testing laboratories in South Korea, China and Taiwan to more closely harmonise emissions testing procedures within round robin tests. Testing laboratories participating in this round robin program have adopted standardised policies and procedures to help ensure that individual tests are conducted consistently, regardless of the laboratory location. This rigorous approach helps to minimise the primary source of differing test results: human error.
