5. DETAILED REQUIREMENTS
5.1 Classification of defects. Defects are considered with regard to character and extent. Defects are classified and limited to fall within one or more of the following classes as specified in ANSI/ASQ Z1.4.
a. Critical. A critical defect is one that judgment and experience indicate could result in hazardous or unsafe conditions for individuals using or maintaining the product; or for major
end-item units of which the product is a component, such as ships, aircraft, or tanks; a defect that could prevent performance of their tactical function.
b. Major. A major defect is a defect, other than critical, that could result in failure or materially reduce the usability of the unit or product for its intended purpose.
c. Minor. A minor defect is a defect that does not materially reduce the usability of the unit or product for its intended purpose or is a departure from established standards having no significant bearing on the effective use or operation of the unit.
5.1.1 Unlisted defects. Unlisted defects, when deemed by the Inspector or Engineering to be such as to adversely affect the serviceability or strength of the fuel cell or fitting, are classified in accordance with the above criteria.
5.2 Use of tables. (See Table V for summary.)
5.2.1 Table I. Corrections of discrepancies listed in Table I are considered to be normal finishing operations and are not counted as defects when properly reworked prior to the time the fuel cell (or fitting) is submitted for acceptance or if the rework is accomplished prior to initiation of stand tests. An "X" in one or more of the columns below "Types of Fuel Cells" indicates the type of cell(s) or fitting(s), or the portion of the cell (interior, exterior) to which a particular inspection is considered applicable.
5.2.2 Table II. This table presents acceptance standards for various defects that may occur on fuel cells that are submitted by the manufacturer for acceptance by the procuring activity. This table is also used for inspection of stand or dissection tested fuel cells (see 5.2.3). The columns below "Type of Fuel Cells" indicate the applicability of each defect with regard to type of cell, fitting, or location of defect (interior, exterior) to which a particular inspection is
