What does it indicate when the 0.1 m³ dial moves during a dial test?

When the 0.1 m³ dial moves during a dial test, it indicates that the piping system is not gas tight. The purpose of the dial test is to assess the integrity of the gas piping. If the dial registers movement, this signifies that gas is escaping from the system, whether through leaks in the piping or connections.

A gas-tight system is one in which no gas escapes, and thus the dial would remain stationary. The movement of the dial directly reflects the presence of gas loss, which points to compromised components that need to be addressed for safety and compliance with regulatory standards. Recognizing this movement is critical for evaluating the safety of gas systems during inspections and maintenance.
