A cleaning verification (CV) is passed when the material used is matches or lighter than the CV card.

• A. Heavier than the CV card
• B. Matches or lighter than the CV card
• C. The CV card must be chemical
• D. Verify by measurement device

Answer: (B)

Cleaning verification uses the CV card as a reference standard for acceptable residue. The idea is that the surface you’ve cleaned should be no more contaminated than the CV card. If the material you used for verification shows the same amount of residue or less, it meets the standard and passes. If it shows more residue than the CV card, it fails because it exceeds the allowed level. The CV card is just a benchmark, not required to be chemical, and the pass criterion is based on this relative comparison rather than requiring a specific measurement device.
