Overview

Validation of SIS valves under IEC/ISA 61511 requires that the maximum permissible leakage rate and leak test detection equipment are specified and documented for each valve. Valve leakage requirements are identified under several classes within international standards. This webinar will cover valve leakage rates specification and specifically:

• standards requirements
• definition of leakage classes
• industry approaches to set leakage classes
• valve leakage specification workflow.
