Introducing Robot Classes

The updated CSA Z434 standard introduces two distinct classes of robots for workplace applications. Class 1 robots are designed for lower-risk environments. They’re smaller, lighter, and operate at reduced force and speed. This means fewer functional safety requirements and potentially lower integration costs. In contrast, Class 2 robots are larger, faster, and capable of higher force output, requiring more stringent safety measures.

Currently, most robots in industrial facilities, warehouses, farms, and greenhouses fall under Class 2. However, with these new classifications, we expect to see more Class 1 robots deployed for lighter-duty applications. This shift could offer businesses a cost-effective way to automate without compromising safety or cycle times.

Enhanced Guidance for Collaborative Applications

The update also expands requirements for collaborative robot applications, where humans and robots share the same workspace. Historically, humans were kept separate from robotic systems, but advances in safety technology now allow for true collaboration. The new standard provides detailed guidance on proximity monitoring, force limitations, and safe interaction protocols.

For example, if a robot in a distribution center picks an item and hands it to a human, the design must minimize risk during contact. Speed, force, and pressure outputs will be strictly limited, and end-effector design will play a critical role in reducing injury risk.

Key Updates You Need to Know

  • Cybersecurity Requirements: Secure access controls, network segmentation, and fail-safe behavior during communication loss.
  • Collaborative Safety Functions: Hand-guided control, speed and separation monitoring, power and force limiting.
  • Biomechanical Limits: Pressure and force thresholds for 29 body areas during human-robot contact.
  • Functional Safety Clarity: Emergency stop, protective stop, interlocking, reset, and mode activation requirements.
  • Measurement Protocols: Validating pressure and force for Power and Force Limiting (PFL) applications.
  • Risk Assessment: New protocols focused on robotic applications.
