Overview
ISO 9283:1998, "Manipulating industrial robots - Performance criteria and related test methods," defines standardized performance criteria and test methods for manipulating industrial robots. It helps manufacturers, integrators and end users specify, measure and report key robot performance characteristics so that robot capabilities can be verified, compared and documented in a consistent way.
Key topics and technical requirements
- Performance characteristics covered: pose accuracy and pose repeatability; multi‑directional pose accuracy variation; distance accuracy and distance repeatability; position stabilization time; position overshoot; drift of pose characteristics; exchangeability; path accuracy and path repeatability; path accuracy on reorientation; cornering deviations; path velocity characteristics; minimum posing time; static compliance; weaving deviations.
- Test conditions: robots must be mounted and prepared per the manufacturer’s instructions; tests normally use a manufacturer‑specified warm‑up (except drift-from-cold tests).
- Environment and units: tests should be conducted under stated operating and environmental conditions (ambient testing temperature recommended at 20 °C ± 2 °C). Units: mm for length, seconds for time, rad/deg for angles.
- Instrumentation and uncertainty: measurement equipment must be calibrated; dynamic response (sampling rate) must be sufficient for path and overshoot measurements. The total measurement uncertainty shall not exceed 25% of the magnitude of the measured characteristic.
- Loads and comparison testing: tests are performed with test loads equal to 100% of rated load (mass, center of gravity, inertia as specified). For valid comparisons between robots, parameters such as test cube size, load, velocities, paths and cycles must be identical; Annex A provides specific parameters for comparison tests.
- Coordinate systems and measurement: measured poses and orientations are reported in a common base coordinate system (see ISO 9787). Measurement points must be defined relative to the robot mechanical interface.
Applications and who uses this standard
- Robot manufacturers - to develop and verify performance specifications and to provide standardized test reports for customers.
- System integrators and OEMs - to validate robot suitability for specific tasks (welding, painting, machining, assembly).
- Quality, acceptance and test laboratories - for type testing, acceptance testing and comparative benchmarking of robot models.
- Procurement and R&D teams - to compare candidate robots objectively using consistent test parameters.
- Safety and compliance engineers - to document performance attributes referenced by other robot standards.
