Notes:
1. For batches of less than 10 pieces, Cognizant Engineers may, in their sole discretion, reduce the sample size for the “lossy” test to 1 piece, subject to the quality of the test and the consent of the Customer.
2. Samples for retyping and refurbishing testing may be selected from the batch for “Appearance Testing – Detail Testing”.
3. Lead test samples can be selected from the batch for “Appearance Test – Detail Test”.
4. Open cover test samples can be selected from the batch undergoing “Retyping and Refurbishing Test”.
