The removal of components within a source system for repair and reinstallation shall be treated as new work for testing whenever work involves?

When removal of components within a source system for repair and reinstallation involves cutting and brazing, it is considered new work for testing due to the potential modifications made to the system's integrity and connections. Cutting and brazing can alter the configuration and structure of the piping, which may affect the performance and safety of the medical gas system.

Moreover, this process can introduce new joints and areas that require pressure testing to ensure they meet safety and performance standards. This is necessary to prevent leaks and ensure the system operates within regulatory guidelines. Testing is crucial after such modifications to guarantee that the system is sealed correctly, compliant with applicable codes, and functioning safely for patient use.

Other activities like cleaning, deburring, or simply removing components may not significantly alter the overall integrity of the system in the same way that cutting and brazing does. Therefore, they do not necessitate the same level of testing and scrutiny as cutting and brazing work does following a repair.
