Which component must be tested and documented in the LPS?

The correct answer is that test item descriptions must be documented in the LPS (Lightning Protection System). This documentation is crucial because it provides a clear understanding of the specific components and their specifications within the system. By detailing the test item descriptions, personnel can verify that all necessary components have been properly assessed, ensuring that they meet safety standards and operational requirements. This clarity helps in maintaining consistency in testing procedures and facilitates future inspections or evaluations.

Additionally, having documented test item descriptions allows for effective communication among personnel involved in maintaining, inspecting, and updating the Lightning Protection System. It serves as a reference point that can help in identifying issues, making decisions regarding repairs or upgrades, and ensuring overall system reliability.
