UNECE WLTP COP task-Force Revision on testing Frequency DRAFT Mandate of the CoP Taskforce The CoP Taskforce shall: .. introduce a harmonised procedure (e.g. statistical approach, sampling frequency etc.) to demonstrate Conformity of Production (CoP) for the Type 1 test in GTR 15 the Type 4 test in GTR 19, and the future UN Regulation WLTP; … Current EU: 1 sample per 5000 vehicles in an IP-family; at least once per year risk assesment necessary to analyze a sufficient number but  high burden for small and large families << and >> 5000 vehicles / year 1

Limit number of samples per year for large families UNECE WLTP COP task-Force Revision on testing Frequency DRAFT Proposal: Allow for COP-families under certain conditions for small families, e.g. Split IP-families due to exceedance of max. range (30g/km) Same engine, same drivetrain, same emission character but different engine power Same engine, same gearbox but 2WD/4WD Separate IP-families only due to gear ratios difference Extend to 2 year-period to finish the sample for <1000 veh/y … Limit number of samples per year for large families 2
