Full title and description
ISO 8866:1991 - Road vehicles — Test procedures for braking effectiveness of motorcycles (including mopeds) — The standard specifies uniform test procedures and conditions for measuring braking performance of two‑wheeled motor vehicles to determine stopping distances, deceleration, and brake system effectiveness.
Abstract
This International Standard provides standardized test procedures for assessing the braking effectiveness of motorcycles, including mopeds. It defines vehicle conditions, test surfaces, speed profiles, braking maneuvers, instrumentation and methods for reporting braking performance such as stopping distance and deceleration. The aim is to provide repeatable, comparable results for vehicle manufacturers, approval authorities and testing organizations.
General information
- Status: Published standard (1991)
- Publication date: 1991
- Publisher: International Organization for Standardization (ISO)
- ICS / categories: 43.060 (Road vehicles engineering); 03.120 (Transportation)
- Edition / version: 1st edition (1991)
- Number of pages: Approximately 16–24 pages (typical for ISO test procedure documents)
Scope
ISO 8866:1991 covers test methods and procedures to evaluate the braking performance of motorcycles and mopeds under defined conditions. It establishes the required vehicle preparation, test track surface characteristics, initial speeds, braking maneuvers (controlled and emergency stops), measurement points, and reporting format so that braking effectiveness can be assessed consistently across different laboratories and road vehicle types within the two‑wheeler category.
Key topics and requirements
- Definition of vehicle categories covered (motorcycles, mopeds) and required pre‑test conditions (mass, load, tyre pressure).
- Specification of test surfaces and environmental conditions to ensure reproducibility.
- Required braking maneuvers (e.g., full emergency stop, controlled stop) and starting speeds for tests.
- Instrumentation and measurement methods for stopping distance, mean fully developed deceleration, and brake system response time.
- Procedures for repeated runs, data averaging and reporting of test results.
- Safety precautions for test drivers and vehicle setup during braking tests.
Typical use and users
ISO 8866:1991 is intended for vehicle manufacturers, type‑approval authorities, independent test laboratories, research institutions and motorcycle safety organizations. Typical uses include type approval testing, comparative assessment of braking systems, regulatory compliance checks, and research into braking performance and rider safety.
Related standards
Standards related to motorcycle braking and vehicle testing include ISO standards on road vehicle testing procedures, national and regional regulations for vehicle braking performance, and other international standards addressing tyre testing, deceleration measurement and brake system components. It is often used alongside more recent or region‑specific regulations and standards for motorcycle safety testing.
