Existing C1 tyre-abrasion test methods cannot be directly applied to C3 tyres because vehicles equipped with C3 tyres are used differently. Japan is developing a vehicle test method using WHVC mode and plans to develop a drum test method based on test conditions and results. Test conditions will convert vehicle driving conditions representing the world into indoor drum test settings. C2 test method uses driving mode based on WLTP with fixed test load details, with verification tests using reference tyres. For C3, driving modes and test conditions are under preliminary investigation, with verification tests to be planned.

Presentation to explain Japan’s preference for using a gauge to ensure a 60° angle over the procedure based on the bumper beam to determine the target impact area for the lower legform.

Explanation of Japanese concerns over differences in the behaviour of the Flex-PLI lower legform impactor in an angled impact compared with a human being based on THUMS analysis in relation to the bumper beam proposal for determining the impact area of the test.

JASIC view urging quick adoption of the bumper test area using a 60° threshold in line with the currently available technology (as opposed to delaying initial implementation while researching and validating further refinements).

Review of a research program to define optimal sound limit values for reversing warning systems considering acceptability (noise environment) and detectability (pedestrian safety).

Presentation of summary and conclusions from a literature review on the biomechanics of minor neck injuries resulting from rear-impact accidents.

Report on consideration of Computational Fluid Dynamics method as a means to simulate aerodynamic drag.

Update from the WLTP New Issues Task Force subgroup on the Computational Fluid Dynamics method for simulation of aerodynamic drag.

Technical report on the development of a uniform light vehicle emissions and fuel-consumption test cycle to represent typical driving characteristics around the world in order to enable the use of a globally harmonized type-approval procedure by 2014.
