ACCEPTANCE CRITERIA Introduction The following acceptance criteria shall be employed to evaluate the paper's conformance to specification. Paper that does not meet all specification values shall be accepted with no discount providing that the minimum acceptable Product Quality Index (PQI) of 70 is met. The PQI for a specific paper is determined by assigning demerits to each deficient quality characteristic based on test results. The demerits assigned will vary with the category of deficiency. A minor defect shall be assigned 4 demerits, a major defect 12 demerits, and a critical defect 36 demerits. Definitions Minor Defect. Any deficiency from specified values which does not materially reduce the usability of the paper for its intended purpose; or require special procedures for printing or processing. Major Defect. Any deficiency from specified values, other than critical, that could result in failure, or materially reduce the usability of the paper for its intended purpose; or may require special procedures for printing or processing, or is a significant deviation from specifications, established standards, or average process capability, or may materially affect the appearance of the product. Critical Defect. Any deficiency from specified requirement that judgment and experience indicate would result in the paper being unusable for its intended purpose; or is a serious departure from specifications, established standards, or average process capability. The equation for the calculaton of the Product Quality Index is as follows: Product Quality Index is equal to 100 minus the sum of the assessed demerits for each paper characteristic or property. i=N Expressed mathematically, PQI=100- Ci i=1 where C=characteristics or properties Paper having a PQI of 70 or better shall be accepted at the contracted price as meeting the intent and requirement of the specification. That having a PQI below 70 shall be considered as critically defective, subject to outright rejection.
