Are Pre-Service tests performed after an apparatus is placed into service?

Pre-Service tests are typically conducted before an apparatus is placed into service, not after. The purpose of these tests is to ensure that all systems and equipment function correctly and safely prior to their operational deployment. This testing phase allows for the identification and correction of any potential issues that may exist, providing confidence that the apparatus will perform as expected under real conditions.

Performing these tests only after the apparatus has been placed into service would not serve the intended purpose of verifying readiness and operational integrity. Additionally, while ongoing maintenance checks are important for ensuring long-term reliability, they are distinct from Pre-Service testing, which focuses on initial validation of new equipment. Therefore, the correct answer aligns with the standard protocols regarding the timing of these tests in relation to the apparatus status.
