GTR 15: Proposal to amend sub23 nm particle provisions of the draft Amendment 6
|
|
Reference Number: GRPE-81-10
|
|
Proposal from the Particle Measurement Programme informal group to: - Modify the existing solid PN measurement methodology having a 50% cut-off size at 23 nm (SPN23) in order to allow the use of catalyzed volatile particle remover (VPR) and introduce minor improvements, and
- Include as a second option a solid PN measurement methodology with a 65% cut-off size at 10 nm (SPN10).

GRPE-81-12 | Brake emissions protocol status update and proposal
|
Brake emissions protocol status update and proposal
|
|
Reference Number: GRPE-81-12
|
|
The first part of the PMP Brake Protocol for measuring brake particle emissions and addresses items using a new WLTP-Brake Cycle in conjunction with an inertia dynamometer test. The PMP Brake protocol will include three sections aiming to provide a comprehensive protocol for testing facilities: - Inertia Dynamometer Protocol to Measure and Characterise Brake Emissions Using the WLTP-Brake Cycle;
- Part 2: Minimum Requirements and Guidelines for Sampling and Measurement of Brake Emissions for Particle Number and Particle Mass;
- Part 3: Reporting Test Results from Brake Emissions Testing.
