Non-volumetric leak testing can adversely affect product quality if the test gas is not inert.

Non-volumetric leak testing can adversely affect product quality if the test gas is not inert.

• A. It never affects product quality.
• B. It can adversely affect product quality if the test gas is not inert.
• C. It always ensures product integrity.
• D. It has no effect on product quality.

Answer: (B)

In non-volumetric leak testing, the gas used to probe for leaks should not react with the product or its packaging. If the test gas is not inert, it can chemically interact with materials, causing oxidation, corrosion, contamination, or residue formation during the test. These reactions can degrade product quality, alter material properties, or introduce contaminants, and they can also create misleading leak indications. That’s why using an inert test gas is important—the test measures physical leakage without changing the product. So the statement that it can adversely affect product quality if the test gas is not inert is the best answer.
