HVIA progresses key VSB6 changes with the National Heavy Vehicle Regulatory – including formal request to remove removal of ‘tipper stability’ calculation
HVIA has formally requested that the NHVR remove the contentious ‘tipper stability’ calculation from the upcoming VSB6 update.
This request follows extensive consultation with members, including at the most-recent round of HVIA state committee meetings.
The stability calculation appears in Part 12 of Section J of the updated version of VSB6 (version 3.2), set to be in-force from the revised date of February 1, 2024. The full text of VSB6 Section J is available here.
The calculation has proven to be contentious for several reasons, which include its complexity, level of detail, and the need for a unique data set that covers tyre stiffness, suspension characteristics, and chassis torsional stiffness, which is difficult to obtain.
HVIA supports initiatives to improve the safety of specific sectors of the industry through design requirements, but the chosen pathways must be workable.
Adam Ritzinger, HVIA’s Chief Technical Officer, is working with NHVR representatives on alternatives, and will also e-mail affected members this week to seek feedback on a specific alternative option proposed by the NHVR.
Please contact Adam on 0437 901 669 or firstname.lastname@example.org to discuss further.
