Two documents for two sets of responsibilities
ISO published the third edition of ISO 10218-1 and the second edition of ISO 10218-2 on February 5, 2025. Together they replace the 2011 editions of the main international safety standard for industrial robots. Part 1 covers the robot as partly completed machinery and is aimed mainly at manufacturers. Part 2 covers the complete robot application or cell and assigns requirements to integrators across design, commissioning, operation, maintenance and decommissioning.
That split reflects how industrial automation is actually delivered. A safe robot arm can become part of an unsafe cell if the end effector, workpiece, layout, guarding or control logic creates a new hazard. Conversely, an integrator cannot compensate for every weakness in the underlying machine. The two documents establish a chain of responsibilities rather than treating a robot's certification as the end of the safety process.
What changed after fourteen years
According to the Association for Advancing Automation, which participated in the revision work, the 2025 editions make functional-safety requirements more explicit. They also incorporate collaborative-application material that previously sat in ISO/TS 15066 and bring guidance for manual loading, unloading and end effectors into the main framework. New robot classifications are paired with safety requirements and test methods.
The revision also addresses cybersecurity where it can affect safety. That does not turn ISO 10218 into a general information-security standard. It recognizes a narrower engineering fact: if a networked control function can be altered, disabled or given unsafe commands, a cyber failure can become a physical hazard. Integrators must consider that link within the application's risk assessment.
Collaborative operation is often misunderstood as permission to place any so-called cobot beside a person. The revised framework still requires the complete application to be assessed. Tooling, payload, speed, accessible crushing points and foreseeable misuse can make an otherwise force-limited arm hazardous. The label on the robot does not validate the final cell.
Scope is deliberately limited
ISO 10218 applies to industrial environments where access is controlled and operators are working adults. Its published scope excludes medical, healthcare, consumer, law-enforcement, military, airborne and space robots, as well as robots that transport people. Separate standards and regulations govern many of those systems.
The documents also do not erase process hazards. Welding, lasers, machining, hot material and chemicals introduce risks beyond robot motion. Part 2 requires the integrated application to address its significant hazards, but specialist machinery and process standards may still be necessary.
Practical consequences for a robot cell
For manufacturers, the new edition affects safety-related control functions, documentation, validation and the information supplied to integrators. For integrators, compliance requires evidence about the full application: defined operating modes, protective measures, stopping behavior, access control, recovery procedures and validation under foreseeable conditions.
An existing cell does not instantly become unsafe because a new edition was published. ISO's Part 1 scope states that it is not applicable to robots manufactured before publication, and local law determines how standards are adopted. However, organizations designing new systems or materially modifying old ones now have a newer consensus reference. National adoptions, such as the 2025 U.S. revision of ANSI/A3 R15.06, translate the international work into local practice.
The real significance is procedural. Fast-moving perception and AI software can change what a robot attempts, but safety still depends on defined limits, verified functions and a risk assessment of the complete application. The 2025 revision gives that work a more current common language.
