APPENDIX A
PROCEDURE FOR QUALIFICATION APPROVAL
A.1 SCOPE
A.1.1 Scope. This appendix details the procedures for submission of samples for qualification inspection of
resistors covered by this specification. The procedure for extending qualification of the required sample to other
resistors covered by this specification is also outlined herein. This is a mandatory part of the specification. The
information contained herein is intended for compliance.
A.2 APPLICABLE DOCUMENTS
A.2.1 Government documents.
A.2.1.1 Specifications, standards, and handbooks. The following specifications, standards, and handbooks form a
part of this document to the extent specified herein. Unless otherwise specified, the issues of these documents are
those cited in the solicitation (see 6.2).

A.2.2 Order of precedence. In event of a conflict between the text of this document and the references cited
herein (except for related associated specifications, specification sheets, or MS sheets), the text of this document
takes precedence. Nothing in this document, however, supersedes applicable laws and regulations unless a specific
exemption has been obtained.
A.3. SUBMISSION
A.3.1 Sample. A sample consisting of 42 highest values 1/ and 42 lowest values, 1/ coated or enclosed resistors
in each style, with the lowest resistance tolerance for which qualification is desired, shall be submitted in accordance
with section 4 of this appendix. In addition, 14 sample units of any resistance value shall be submitted and subjected
to the tests of groups II and 10 sample units shall be submitted to group VIII. Four uncoated or unenclosed resistors
(Two at the highest value and two at the lowest value), shall also be submitted in each style. 2/ If enclosures are
used in lieu of coatings, four enclosures shall be furnished.
A.4. EXTENT OF QUALIFIACTION
A.4.1 Resistance values. The extent of qualification of resistance values for each style shall range between the
highest and lowest values qualified.
A.4.2 Tolerances. The extension of qualification between tolerances shall be in accordance with table A-I:
A.4.3 Styles. The extension of qualification between styles can be accomplished by submitting the largest physical
size for which qualification is sought as shown in table A-II. Similar enclosure materials and construction must be
utilized for cross qualification.
⎯⎯⎯⎯⎯⎯
1/ One additional sample unit of each resistance value shall be submitted to permit substitution for the allowable
defect in group 1 inspection.
2/ The uncoated and unenclosed resistors shall be individually packaged to preclude damage in shipment.
