Text as revised during the 15th LNG Task Force session.

The purpose of this 2018 study was to establish the scale of vehicles with manipulated odometers imported from Germany, to investigate how odometer manipulation can take place, and to identify bottlenecks in combating odometer manipulation in vehicles imported from Germany.

This presentation analyzes RD-ASEP model performance using test run data from Annex_9_test_runs where both left and right sound were measured. Current model shows 1.3% of measurements above L_exp; without the 2 dB margin this increases to 8.4%. Model overestimates at low speeds and underestimates at higher accelerations. Tyre rolling sound parameters have most influence on results and dominate most of the data set. Optimizing all 13 parameters reduces mean absolute error from 2.1 to 1.1 dB. More high acceleration measurements are needed to reliably calibrate the dynamic component.

This presentation, intended for discussion within TF Data Analysis RD-ASEP and not for conclusions, analyzes model performance using L_exp data from Annex_9_test_runs where both left and right sound were measured. Model performance varies across speed bins, with higher mean absolute error at low and high speeds. Adjusting theta_tr values improves mean absolute error across all speed bins. Testing without an envelope function results in more measurements exceeding expected values, requiring extra margins.

Email from the DETA secretary providing an update on the status of the DETA project and its eventual application to lighting products under the Simplification of Lighting Regulations.

Discussion document presenting general considerations for a C3 tyre abrasion test method. Topics addressed include objectives for reducing C3 tyre wear, quantification of C3 abrasion relative to overall and C1 abrasion, C3 tyre life including retreading effects, operational factors influencing tyre wear such as fleet optimization and load management, and environmental concerns regarding C3 microplastics and chemical requirements.
