In an antifreeze system, what is the basis for determining additional test points?

In an antifreeze system, the determination of additional test points is based on the system's capacity, specifically measuring at intervals. The correct choice indicates that for every 100 gallons of antifreeze in the system, there is a requirement for additional testing points to ensure the system’s effectiveness and compliance with NFPA 25 standards.

This approach is important because it enables proper oversight of antifreeze concentration and ensures that all areas of the system are adequately maintained. The practice allows for a consistent and thorough inspection process to ensure that the antifreeze system is functioning correctly and adhering to safety regulations. Therefore, as the capacity of the system increases, more test points are necessary to monitor system performance appropriately, reflecting the need for increased diligence with larger systems.
