Which test is performed after installation to ensure the system operates as intended before it becomes active?

• A. Verification Test
• B. Validation Test
• C. Commissioning Test
• D. Acceptance Test

Answer: (D)

Acceptance testing is the formal check done after installation to prove the system works as intended under real operating conditions and meets the contract and design criteria before it is allowed to operate. This stage provides the owner’s sign-off and often involves demonstrating that performance, safety, and interlocks meet the specified requirements, ensuring readiness for activation. Verification tests focus on confirming that each component was built and installed according to the design documents, typically verifying conformance to specifications. Validation tests assess whether the system meets the user’s needs in the intended environment, which is broader than just meeting design criteria. Commissioning tests cover the startup and integration process to bring the system to an operational state, often during the transition from installation to active use.
