APPENDIX A

A.3.  SUBMISSION

A.3.1  Sample.  A sample consisting of 40 sample units, each of the lowest and highest resistance values having a resistance tolerance of 1 percent, in each style and characteristic for which qualification is sought, shall be submitted.  If the lowest resistance value is below the critical value listed in table A-I,

and the highest resistance value is above the critical value, then 40 sample units of the critical value shall also be submitted.  If approval for a lower tolerance is desired, an additional 10 samples unit, each of the

lowest resistance tolerance for which approval is sought, shall be submitted to the inspection of group I in

table V.  At the option of the supplier, a sample consisting of 40 sample units, each of the lowest and highest resistance values having a lower (tighter) resistance tolerance than 1 percent in each style and characteristic for which qualification is sought shall be submitted.

TABLE A-I.  Critical resistance values.

A.4.  EXTENT OF QUALIFICATION

A.4.1  Extent of qualification.  The resistance range included in the qualification of any one resistor style and characteristic will be between any two adjacent resistance values which pass the qualification inspection.  Qualification will cover only the resistor types covered by description of 3.1.  Separate submissions are required for each type protective enclosure or coating used.  Qualification of one characteristic is basis for qualification of another characteristic, as indicated in table A-II.  Also, qualification of the lower resistance tolerances will qualify the higher resistance tolerances in accordance with table A-III.
