Test Procedure Development Methodology
The DTP subgroup is tasked with creating a worldwide harmonized test procedure for light-duty vehicles. This involves synthesizing input from all WLTP DTP subgroup members, developing, and validating the test procedure through validation, confirmation, and round-robin tests. The DTP will work independently through subgroups on specific issues, while ensuring overall coordination and consistent drafting. SI units will be used, and criteria including emissions, CO2, and fuel consumption will be emphasized. The goal is to enable future European legislation to reference the defined procedures transparently.

Test Procedure Development Methodology The DTP subgroup will undertake the following tasks: Devise a methodology for the development of a worldwide harmonized light-duty test procedure; Synthesize input from all WLTP DTP subgroup members; Develop and validate a world harmonized light-duty test procedure (activities to include validation, confirmation and round-robin tests).

Test Procedure Development Methodology Working methods Separation of tasks between DHC and DTP is required. Working subgroups will be required to address specific issues. Subgroups will work independently and report to the main DTP group. Main WLTP-DTP group will be responsible for overall coordination of the subgroups, consistent drafting of the procedures, and resolution of generic issues. WLTP-DTP-01-11

Test Procedure Development Methodology Requirements for the DTP Default test procedures of the WLTP-GTR must be defined with sufficient accuracy that future European legislation can refer to them in an editorially transparent and consistent manner. - per EU input WLTP-GTR will be an international document and as such should reflect ISO standards.
