UL is offering functional safety certification, and the Control Engineering Machine Control has advice on functional safety certification, with a place to leave your views and questions.

In addition to evaluating products for functional safety, UL also said it would:

  • Develop Validation Plans
  • Develop Safety Requirements Specification (SRS)
  • Develop Failure Modes and Effects Analysis (FMEA)
  • Develop Failure Modes, Effects, and Diagnostic Analysis (FMEDA)
  • Develop Safety Plans
  • Develop Software FMEA/Software Hazard and Operability (HAZOP) Analysis
  • Develop integrated test plan, including identifying appropriate environmental conditions for testing (such as humidity, EMI, vibration, etc.)
  • Create safety manual
  • Develop safety case, including development of risk analysis
  • Draft functional safety management plan
  • Calculate or verify Safety Integrity Levels (SIL), Performance Level (PL), or Class, etc.

UL will also provide:

  • Functional Safety Component Recognition Mark
  • Functional Safety Listing Mark
  • Functional Safety Test Reports
  • IEC 61508 Introductory Training
  • IEC 61800-5-2 Functional Safety in Motor Drives Training
  • 3-year Functional Safety Certificate
  • Type examination report
