Proof Test Procedures & Verification Service

aeSolutions provides Proof Test Procedure development and verification services to ensure Safety Instrumented Functions (SIFs) perform as required and continue to meet their intended Safety Integrity Level (SIL). Our structured, lifecycle-based approach aligns with IEC 61511 and focuses on developing practical, effective testing strategies that validate system performance and uncover hidden failures.

​

Our Proof Testing & Verification Capabilities Include:

• Development of proof test procedures aligned with IEC 61511 requirements

• Identification of test coverage to detect dangerous undetected failures

• Verification of proof test intervals and alignment with SIF design assumptions

• Evaluation of instrumentation, logic solvers, and final elements performance through functional testing

• Documentation of step-by-step test procedures for field execution

• Review and optimization of existing proof test practices and intervals

• Support for test execution, results documentation, and performance tracking

​

aeSolutions works closely with your engineering, operations, and maintenance teams to develop and validate proof test procedures that are practical, executable, and aligned with real-world operating conditions. Whether supporting new system commissioning or improving existing testing programs, our expertise helps ensure your safety systems remain compliant, effective, and aligned with your facility’s design assumptions.
