3. 1. CRITICAL DEFECT:
▪ “A critical defect is a defect that judgment and experience indicate is likely to result in hazardous or unsafe
conditions for individuals using, maintaining or depending upon the product.” . Zero tolerance will be
applied to the acceptable quantity of critical defects found within a shipment. A critical defect will
automatically render the inspection as rejected.
2. MAJOR DEFECT:
▪ “A major defect is a defect, other than critical, that is likely to result in failure or to reduce materially the
usability of the unit of product for its intended purpose.” In simple terms, a major defect is likely to result
in product failure, either initially or within a short period of time. A major defect will result in the end-
user rejecting and returning the product. AQL chart will be followed for Major defects—including critical
measurement points that are out of tolerance .
▪ “A minor defect is a defect that is not likely to reduce materially the usability of the unit of product for its
intended purpose.” In other words, a minor defect may cause some end-user dissatisfaction but may not
cause the end user to reject and return the product. AQL chart will be followed for Minor defects—
including non-critical measurement points that are out of tolerance.
