considered applicable.
5.2.3 Table III. This table lists inspections and defects that are unique to stand tested fuel cells. For stand tested cells, the inspections listed in Table III are conducted in addition to the inspections in Table II. Stand tests are normally conducted in fixtures lined with indicator paper. The "stains" referred to in Table III, are stains showing on an indicator paper when cells are defective. If an alternate method of leak detection is used for stand tests, equivalent criteria
are used for defect classification. Leaks that cannot be attributed to physical damage or shown to be a unique case are classified as a critical defect.
5.2.4 Table IV. Table IV lists additional defects that are applicable to dissection tested fuel cells. These inspections are conducted on dissection tested cells in addition to the inspections in Table II. Item 6 in Table IV is applicable to replacement fuel cell fittings that are subjected to dissection tests on a sampling basis as well as to dissection tested cells.
5.2.5 Table V. Table V summarizes the contents of 5.2 and 5.3.
5.3 Action to be taken on identified defects. (See Table V for a summary of these actions.)
5.3.1 Minor defects. Discrepancies classified as minor defects are considered acceptable without rework provided they do not exceed the following limits:
a. Fuel cell interior - One defect per 10 square feet of total cell area. Where an accumulation of minor defects is not greater than the limits specified in the table, they will be considered one defect. For example, an accumulation of five 1/4-inch blisters in any one 5-foot length of splice (Table II, defect 1a) is counted as one minor defect.
b. Fuel cell exterior - Not greater than limits specified in table.
c. Installed fuel cell fittings - Minor defects in installed fittings are counted and included when determining acceptability of fuel cells without rework in accordance with 5.3.1, a and b.
d. Replacement fuel cell fittings - Replacement fittings submitted for acceptance are considered as acceptable without rework if minor defects are not greater than the following:
(1) Fittings with bolt circles of 6 inches or less - two minor defects permitted.
(2) Fittings with bolt circles larger than 6 inches - three minor defects permitted.
For non-circular fittings, consider bolt circle to be the largest dimension of the fitting. Minor defects greater than the criteria listed above are considered a major defect and reworked prior to acceptance.
5.3.2 Major defects. Major defects in fuel cells or replacement fuel cell fittings submitted for acceptance under a production contract are corrected using an approved rework procedure
