Release of PAK pass-by 1.9

Tightening legal requirements for exterior noise emissions, an increasing model diversity, and limited availability of resources and time make a flexible and robust system solution necessary for pass-by measurements.

The new version 1.9 of the PAK pass-by application contains besides the ongoing updates of already integrated standards for the tire roll noise and idle noise measurements various implementations of further standards. Users always test worldwide with PAK pass-by application according to the latest legal requirements for all vehicle types. With PAK pass-by, users can evaluate with one system the exterior noise across multiple country-specific standards.

The most important new standards at a glance:

  • UNECE-R51.03 Revision 3 Supplement 1 Annex 3 for the vehicle classes M2>3500kg, M3, N2 and N3
  • UNECE-R51.03 Revision 3 Supplement 2/3 Annex 7 for the vehicle classes M1 and N1
  • US CFR 49 Part 571.141 (FMVSS141) Minimum Sound Requirements for Hybrid and Electric Vehicles

Improvements around usability, reliability, and performance round off the new version.
