Under the conditions described above, compounds naturally present in the wine will not produce interfering peaks on the chromatogram of the sample solution.

As of 1 September 2017, new car models will have to pass new and more reliable emissions tests in real driving conditions ("Real Driving Emissions" – RDE) as well as an improved laboratory test ("World Harmonised Light Vehicle Test Procedure" – WLTP) before they can be driven on European roads.

14. Considers that the upcoming review of the type-approval framework directive must expand and specify the requirements for conformity of production so as to ensure that a sufficient and representative sample of new models, taken at random off the production lines, is tested annually using RDE tests to verify compliance with European pollutant and CO2 limit values; calls furthermore for improved in-service testing of vehicles already in use on the road – likewise on the basis of the RDE procedure – in order to verify in-service conformity of vehicles at different mileages as required under the Regulation; calls for an improvement of o ...[+++]n-road surveillance through periodic technical inspections to identify and repair vehicles which are found not to be in compliance with EU law;

21. Considers that the upcoming review of the Type Approval Framework Directive must consider expanding and specifying the conformity-of-production requirements in order to ensure that a sufficient and representative sample of new models taken off production lines at random are tested on an annual basis, using RDE tests to check their compliance with EU pollutant and CO2 limit values; calls, furthermore, for improved in-service testing of vehicles already in use on the road, also on the basis of the RDE procedure, in order to verify the in-service conformity of vehicles at different mileages as required under the regulation; calls for the imp ...[+++]rovement of on-road surveillance through periodic technical inspections to identify and repair vehicles which are found not to be in compliance with EU law;
