About ISO/TS 15066 (Collaborative Robot Safety)

This event covers the compliance, engineering, and verification requirements defined by ISO/TS 15066.

ISO/TS 15066 supplemented ISO 10218 with the detailed requirements for collaborative robot operation — most notably the biomechanical force and pressure limits for power-and-force-limited contact and the protective separation distance math for SSM; its content is absorbed into the 2025 editions of ISO 10218.

What it regulates

The four collaborative methods, quasi-static and transient contact thresholds per body region, measurement methodology for contact validation, and SSM distance computation.

Who must comply

Cobot application integrators validating contact cases with force/pressure measurement devices; still cited widely during transition to the 2025 10218 editions.

Key requirements of ISO/TS 15066

  • Body-region pain-onset limit tables (pressure and force, quasi-static vs transient)
  • PFL application design: contact case identification and mitigation
  • SSM protective separation distance formula and its terms
  • Hand-guiding and SMS operational requirements

Key concepts: ISO/TS 15066

Contact case matrix
The enumeration of foreseeable contact events (body region × robot feature) each validated against limits.
Protective separation distance
The SSM minimum distance accounting for robot and human speeds, stopping performance, and detection latency.
Quasi-static contact
Clamping/crushing contact where a body part is trapped — governed by the lower force/pressure limits.
Transient contact
Free impact without trapping, allowed higher short-duration limits.

Frequently asked questions: ISO/TS 15066

Is TS 15066 still applicable?

Its requirements live on inside ISO 10218-1/-2:2025; during transition, citing either is common, and the biomechanical tables remain the reference data set for PFL validation.

How are PFL limits verified in practice?

With calibrated biofidelic force/pressure measurement devices placed at identified contact points while the robot executes worst-case motions; results per body region must stay under the tables, else speed, geometry or padding changes are iterated.
