Description (English):

Specifies method of measuring the performance of service braken, based on measured deceleration and on measured stopping distance, and of parking brakes of vehicles. Applies to: tractors and self-propelled vehicles having a maximum design speed exceeding 6 km/h; trailed vehicles designated for use at speeds exceeding 6 km/h, comprising trailers, towed machines and implements. Annex A gives a specimen test report for tractors and self-propelled vehicles; annex gives a specimen test report for trailed vehicles.

Abstract

Overview

ISO 5697:1982 specifies standardized methods for determining the braking performance of agricultural and forestry vehicles. It covers procedures to measure the performance of service brakes (using measured deceleration or stopping distance) and parking brakes for:

tractors and self‑propelled agricultural/forestry vehicles with maximum design speed > 6 km/h, and
trailed vehicles (trailers, towed machines and implements) intended for use at speeds > 6 km/h.

The standard defines test sequences (cold, fade, recovery), required test conditions and reporting formats (Annex A for tractors/self‑propelled vehicles; Annex B for trailed vehicles).

Key topics and requirements

Two primary measurement methods:
- Method based on measured deceleration (decelerometer data).
- Method based on measured stopping distance (distance from brake application to full stop).
Service brake test sequence: cold performance (Type 0), fade tests (Type 1 and Type 2 where applicable) and optional recovery tests (Type 3). Tests are performed first on the laden vehicle, then on the unladen vehicle.
Parking brake test: defined procedure to verify the ability to hold the vehicle stationary on a slope.
Test site and conditions: dry, clean concrete/bituminous surface with good adhesion; longitudinal slope ≤ 1% and side slope ≤ 3%; wind velocity
