UN R13-H — Braking for M1 and N1 vehicles
Assess braking performance against the relevant vehicle category.
Explore the scopeWhat does it cover?
UN R13-H concerns braking of M1- and N1-category vehicles. It excludes vehicles with a low design speed and certain special vehicles, and states that approval of electronic stability control (ESC) and brake assist systems (BAS) falls outside its scope. It therefore separates braking assessment from approval of those related functions.
Who is it for?
Passenger-car and light-commercial-vehicle manufacturers, and braking-system and testing teams.
Which subjects are addressed?
- M1 and N1 braking scope
- Low-speed exclusion
- Distinction from ESC/BAS approval
- Technical requirements and approval
Common question
Does this regulation approve ESC and BAS?
No. Its scope excludes vehicle approval for ESC and BAS. Assess those functions under the relevant provisions separately.
