ISO 7975 specifies an open-loop test procedure to examine the effect of braking on course holding and directional behavior of a vehicle. Specifically, the method determines how the steady-state circular response of a vehicle is altered by a braking action only. ISO 7975 is applicable to passenger cars as defined in ISO 3833 and to light trucks.
ISO 7975 on Passenger cars — Braking in a turn — Open-loop test method is applicable to:
Braking is the most important function of any vehicle. ISO 7975 gives test to examine the effect of braking on course holding and directional behaviour of a vehicle. Specifically, the method determines how the steady-state circular response of a vehicle is altered by braking action only. This can be used by you to improve braking performance.
The main purpose of ISO 7975 is to provide repeatable and discriminatory test results that can be helpful to testing facilities, car manufacturers and regulatory authorities.
BS ISO 7975:2019 is the fourth edition that cancels and replaces the third edition (ISO 7975:2006), which has been technically revised. The main changes compared to the previous edition are as follows:
