Holiday test or a Continuity test is one of the non destructive test method applied on protective coatings to detect unacceptable discontinuities such as pinholes and voids.
The test involves checking of an electric circuit to see if current flows to complete the electrical circuit.
A Holiday test or Continuity test is performed by applying low voltage (connected in series with an LED or noise-producing component such as a piezoelectric speaker) across the chosen path.
If the electrical flow is detected then the test area is termed as conductive indicating presence of discontinuities such as pinholes and voids.
This test is commonly used in the offshore industries where piping and structures are coated with nonconductor coatings.

What is the code that require a Pipe Hydro Test Package?
The code that typically requires a Pipe Hydro Test Package is the ASME B31.3, which governs the design and construction of process piping. This code mandates hydrostatic testing as a means to verify the integrity and leak-tightness of piping systems. Additionally, other codes such as ASME B31.1 for power piping may also have similar requirements. Compliance with these codes ensures safety and reliability in piping systems under operational conditions.

Can gas piping be bonded to the electrical grounding system?
Gas piping should not be bonded to the electrical grounding system. It should have a separate bonding connection that complies with local building codes. Bonding gas piping to the electrical grounding system can create safety hazards and is not recommended.
