The design validation is to verify the design before it moves to the implementation stage. A functional Safety Assessment can be undertaken after implementation and must be undertaken after stage 3 before the system goes live of the safety life cycle. Stage 2-After the safety instrumented system has been designed.
With years of experience in applying standards in the process industry for a variety of customers we have developed a proven methodology and process for SIS.
What We Do
Pilz take a number of measures for the Design Validation including:
- Confirming the HAZOP/Risk Assessment in place
- Checking the SRS conforms to the requirements of the HAZOP/Risk Assessment
- Review the SIS to ensure it meets the SIL required
- Safety Integrity Level (SIL) Verification
- Review the Hardware selected
- Review the Electrical drawing and P&ID’s
- Software Review
- Ensuring Safety Lifecycle Structure and planning are in place
- The Design Validation ensures that the requirements of the SRS are captured in the design before it proceeds to the implementation stage and therefore minimises delays, costs and disruption associated with unforeseen anomalies in the design.
