Part 4.
                          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.
