How are air test fittings utilized in damage investigation?

Air test fittings are crucial in damage investigation as they allow technicians to assess the integrity of the system being inspected. When fittings are loosened, the sound of air rushing in or out can indicate leaks or breaks in the system. This auditory evidence is instrumental in pinpointing the exact location and nature of the damage, as the sound patterns can reveal whether there is a significant defect.

This method relies on the physical properties of air and pressure, making it a practical approach that can quickly provide insights into system failures without the need for more complex or costly technology. It emphasizes the sound of the air movement to detect faults that may not be visually evident. Therefore, utilizing air test fittings by loosening them and listening for air is an effective technique in the context of damage investigation.
