Robot Safety Certifications 2026

Safety certification is what separates a lab prototype from a deployable product. This guide explains the standards that govern robots in 2026 — industrial arms, cobots, AMRs, and medical robots — and how functional safety, CE marking, and FDA clearance actually work.

1. Why Certification Exists

Standards translate "the robot must be safe" into testable engineering requirements. They protect people, enable market access (you often cannot sell without them), and provide a defensible basis for a design.

2. The Foundation: Risk Assessment

• ISO 12100: the base machinery-safety standard — hazard identification and risk reduction.
• ISO 14971: the equivalent risk-management standard for medical devices.
• Every certification path starts here: identify hazards, estimate risk, reduce it, document.

3. Industrial Robots: ISO 10218

• ISO 10218-1: safety requirements for the robot (the arm itself).
• ISO 10218-2: the robot system and integration (cell, guarding, application).
• 2025 revision: the updated ISO 10218 consolidated collaborative requirements.
• Key ideas: safeguarded space, protective stops, safety-rated functions.

4. Collaborative Robots: ISO/TS 15066

• What it adds: the detailed collaborative-operation requirements for cobots.
• Four modes: safety-rated monitored stop, hand guiding, speed & separation monitoring (SSM), power & force limiting (PFL).
• PFL biomechanical limits: maximum contact force/pressure per body region.
• Reality check: a "cobot" is only collaborative after validated contact-force testing for the specific application.

5. Mobile Robots: ISO 3691-4

• What it covers: driverless industrial trucks and AMRs.
• Requirements: safety-rated scanners, protective stop/slow zones, speed limits.
• Sensing: certified LiDAR (e.g. SICK/Pilz) with monitored fields.
• Applies to: warehouse and logistics AMR fleets.

6. Functional Safety: ISO 13849 & IEC 61508/62061

# Functional safety quantifies how reliable a safety function is.
# ISO 13849 uses Performance Level (PL) a..e:
#   PLd / PLe  -> typical for robot protective stops & SSM
#
# IEC 61508 / 62061 use Safety Integrity Level (SIL) 1..3.
#
# Determined by: severity x frequency x avoidability of the hazard.
# A safety function's architecture (category B,1..4), MTTFd, and
# diagnostic coverage together yield the achieved PL.

7. CE Marking (Europe)

• Machinery Regulation 2023/1230: replaces the Machinery Directive (transition into 2027).
• Process: apply harmonized standards, compile a technical file, issue a Declaration of Conformity, affix CE.
• Notified body: required for certain higher-risk machinery categories.
• CE is self-declaration for most robots — but the technical file must be real and defensible.

8. US: OSHA, ANSI/RIA & NRTL

• ANSI/RIA R15.06: the US adoption of ISO 10218 for industrial robots.
• ANSI/RIA R15.08: covers industrial mobile robots (AMRs).
• OSHA: enforces workplace safety; references consensus standards.
• NRTL listing (UL/TÜV): electrical safety certification for the US market.

9. Medical Robots: FDA & IEC 60601

• IEC 60601: electrical safety for medical electrical equipment.
• IEC 62304: medical device software lifecycle.
• FDA 510(k) / De Novo / PMA: US clearance/approval pathways by risk class.
• EU MDR 2017/745: the European medical device regulation.

10. A Practical Path to Certification

• 1. Risk assessment (ISO 12100 / 14971) — the foundation for everything.
• 2. Identify applicable standards for your robot type and market.
• 3. Design safety functions to the required PL/SIL.
• 4. Validate & test — measure forces, verify stops, document.
• 5. Compile the technical file and declare conformity (engage a notified body / NRTL as needed).

Key Takeaways

Robot safety certification builds on a risk assessment (ISO 12100 / ISO 14971), then applies the standards for your class: ISO 10218 + TS 15066 for industrial and collaborative arms, ISO 3691-4 for AMRs, and IEC 60601 for medical robots. Functional-safety standards (ISO 13849 PL, IEC 61508 SIL) quantify how reliable each safety function must be, and CE marking or FDA clearance gates market access. Treat certification as a design input from day one — retrofitting safety is far more expensive than engineering it in.
