EN ISO 13849-1 Seminars

Service Detail from Schmersal Inc.

Hazard analysis and implementing machine safety is becoming more complicated. We're here to help.

Risk Assessment to EN ISO 13849-1
ISO 13849 is a global harmonized standard relating to the risk assessment, design, and performance of safety control systems on machinery. This standard is accepted world-wide as the principle safety control design guideline and it represents a major change in the philosophy of hazard analysis and design of safety related parts of machine control systems.

During this 7 hour seminar we will review in detail:

  • Why was ISO13849 Created
  • How do we apply it to a machine
  • Understanding Performance Levels Categories
  • Common Cause Failures
  • Diagnostic Coverage
  • MTTFd (Mean Time To Dangerous Failure)
  • PFHd (Probability of Dangerous Failure Per Hour)
  • Symbolic Blocks
  • Fault Exclusions
  • Validation
  • Maintenance
  • Documentation
  • Calculating Safety Functions
