Nonconformity (ISO def.)
A condition of any product or component in which one or more characteristics do not conform to requirements. Includes failures, deficiencies, defects, and malfunctions. [Synonym: Defect](TR43)(TR76)

Nonconformity Classifications
Critical: A Nonconformity that is likely to result in personal injury or potential hazard to the patient. This classification includes any nonconformity that compromises the integrity of the container, and risks microbiological contamination of a sterile product.
Major A: A Nonconformity leading to serious impairments, for example, a malfunction that makes the packaging unusable.
Major B: A Nonconformity leading to impairments of a lesser degree, for example, reduced efficiency in production.
Minor: A Nonconformity that does not impact product quality or process capability.
N/A: An imperfection classification that is less than the size, magnitude and impact of a nonconformity is considered not applicable. Therefore an imperfection that is considered to be non-applicable is acceptable.(TR43)Critical: A nonconformity that risks personal injury or potential hazard to the patient. Any nonconformity that risks container closure in¬tegrity is assigned to this classification.
Major A: A nonconformity leading to serious container impairments, e.g., a malfunction making packaging unusable.
Major B: A nonconformity leading to contain¬er impairments of a lesser degree, e.g., reduced efficiency in production.
Minor: A nonconformity that does not impact product quality or process capability.
N/A: Imperfections that are considered to be nonapplicable or nondefects and are therefore acceptable.(TR 76) -
Nondestructive
A method in which a passing sample can subsequently be utilized in additional analytical methods or processed to a final product. (TR86) -
Non-fiber Releasing
Refers to a filter that does not shed fibers into the filtrate. (TR26)
-
Nonfiber Releasing Filter
Nonfiber-releasing filter means any filter, which after any appropriate pretreatment, such as washing or flushing, will not release fibers into the component or drug product that is being filtered. All filters composed of asbestos are deemed to be fiber-releasing filters. (TR45)
-
Noninferiority
A comparison with the primary objective of showing that the result from one method is not inferior to the method being compared. This is usually demonstrated by showing that the true difference is likely to lie above the lower equivalence margin. (TR57)
-
Nonspecific Model Virus
A virus used for characterization of viral clearance of the process when the purpose is to characterize the capacity of the manufacturing process to remove and/or inactivate viruses in general (i.e., to characterize the general viral clearance capacity of the purification process.) (TR41)
-
Nonviable
A term used in reference to particulates that are not capable of living, growing, or developing and functioning successfully (“unable to divide” or “not capable of reproducing”). (TR13)
-
Normal Dose
The therapeutic dose of a product as given on the approved product labeling. (TR29) (TR49)
-
Normal Operating Range (NOR)
A defined range, within (or equal to) the Proven Acceptable Range, specified in the manufacturing instructions as the target and range at which a process parameter is controlled, while producing unit operation material or final product meeting release criteria and CQAs. (TR60) (TR60-2)
