Overview
ISO 20957-6:2021 - "Stationary training equipment - Part 6: Treadmills" specifies additional safety requirements and test methods for treadmills, to be applied together with ISO 20957‑1 (the general requirements for stationary training equipment). It covers both power-driven and manually driven treadmills and addresses foreseeable misuse, significant hazards, and safety verification for units manufactured after publication. The standard applies to mechanical classes S, H and I and accuracy classes A, B and C.
Key Topics
The standard focuses on practical safety and verification topics for treadmill design, manufacturing and testing, including:
- List of significant hazards relevant to treadmill operation and maintenance
- Classification by machine type and accuracy class (S, H, I; A, B, C)
- Safety stop (emergency stop) requirements, characteristics and actuator testing
- Transmission elements and rotating parts protection and testing
- Immobilization method and stability in training and folded positions
- Static strength and endurance testing of the running surface and structure
- Handrails, foot rails and running surface design and load tests
- Acceleration limits and verification for power-driven units
- Heart rate control mode requirements and testing where provided
- Folding treadmills: locking mechanisms, inadvertent release and handling-force tests
- Temperature rise, noise and electrical safety testing and limits
- Marking, test report and additional instructions for use required for conformity
Applications
Practical uses of ISO 20957-6:2021 include:
- Product design and development teams using the standard as a safety checklist for treadmill features (emergency stop, handrails, folding locks, running-surface strength).
- Manufacturers preparing type-testing, conformity documentation and product marking for CE or other market access.
- Test laboratories and conformity assessors executing the standard’s specified test methods (endurance, stability, acceleration, noise, electrical checks).
- Procurement specialists and facility managers (gyms, rehabilitation centers) specifying equipment that conforms to recognized safety standards.
- Compliance officers and risk managers reducing liability by ensuring foreseeable misuse and significant hazards are addressed.
