Proof Test
Periodic test verifying safety function operates correctly when demanded.
Key Takeaways
- Periodic test verifying safety function operates correctly when demanded.
- Advanced-level topic in Safety Systems
Detailed Definition
Periodic test verifying safety function operates correctly when demanded. This term is essential for understanding safety systems in industrial automation and PLC programming. It represents a key concept that professionals encounter regularly in their work with control systems and automation projects.
Safety engineering is unforgiving, and Proof Test is part of the structured approach to making industrial machinery safe. Periodic test verifying safety function operates correctly when demanded.
Compliance with EN ISO 13849-1 or IEC 61511 means that Proof Test contributes to a calculation of system reliability, not just a yes/no statement of safety. Engineers use tools like Siemens SISTEMA or Pilz PAScal to aggregate components into a function-level performance level.
Insurance, OSHA inspectors, and machinery-directive auditors all expect Proof Test to be addressed by both engineering and paperwork. The two combined are the safety case; either alone is insufficient.
