Overview
ISO 8710:2010 - "Motorcycles - Brakes and brake systems - Tests and measurement methods" defines uniform, repeatable test methods and measurement parameters for the service and, where applicable, parking brake systems of road‑going two‑wheeled motorcycles (3‑3), motorcycles with sidecar (3‑4) and tricycles (3‑5). The standard establishes global procedures for dynamic and failure tests to assess braking performance. It excludes motorcycles with a maximum speed under 25 km/h and vehicles specially equipped for disabled riders.
Key topics and technical requirements
- Test types specified
- Dynamic tests: dry stop (single control and all-service controls), high speed, wet brake, heat fade, parking brake.
- Failure tests: partial failure (for split service brake systems) and power-assisted brake system failure.
- Defined measurement parameters
- Test speed (V), stopping distance (S), mean fully developed deceleration (MFDD), peak braking coefficient (PBC), and wheel lock (slip ratio = 1.00).
- Test site and environmental controls
- Surface: clean, dry, level, nominal PBC = 0.9 for dynamic tests.
- Wind: average ≤ 5 m/s; Ambient temperature: 4 °C to 45 °C.
- Test lane widths specified for two‑wheelers and wider vehicles (sidecar/tricycle).
- Vehicle preparation and loading
- Tyre pressures per manufacturer, engine idle settings, mass-in-running-order and laden mass definitions, instrumentation and burnishing procedures.
- Reporting and equivalence
- Test sequences, control application methods, brake temperature measurement, and a specimen test result sheet are included. Methods are stated to be equivalent to corresponding procedures in UNECE Global Technical Regulation No. 3.
Practical applications - who uses ISO 8710:2010
- Motorcycle manufacturers (OEMs) - for design validation, type approval testing and production verification of brake systems.
- Test laboratories and certification bodies - to perform standardized dynamic and failure tests for regulatory compliance and customer certification.
- Regulators and type‑approval authorities - to harmonize approval criteria and ensure consistent braking safety across markets.
- Brake component suppliers and R&D teams - to validate component performance (calipers, discs, pads, boosters) under repeatable conditions.
- Safety engineers and consultants - for forensic testing, performance benchmarking and development of maintenance/test protocols.
