APPENDIX A
PROCEDURE FOR QUALIFICATION INSPECTION
A.1. SCOPE.
A.1.1 Scope. This appendix details the procedure for submission of sample, with related test results, for
qualification inspection of resistors covered by this specification. The procedure for extending qualification required
sample to other resistors covered by this specification is also outlined herein. This appendix is a mandatory part of
the specification. The information contained herein is intended for compliance.
A.2. APPLICABLE DOCUMENTS. This section is not applicable to this document.
A.3. SUBMISSION
A.3.1 Sample. A sample shall be submitted with shafts 2.5 inches long except for locking bushing type resistors
which shall be submitted with their longest shaft length (see table III).
A.3.1.1 Qualification sample when qualification is sought for resistors with and without electrical off position. For
qualification of standard bushing, or two hole mounting types, eight sample units without an electrical off position and
with the highest nominal total resistance value for which qualification is sought, and four sample units in the same
style with electrical off position symbol 2 (see 1.2.1.1) and with the applicable nominal total resistance value specified
in table A-I shall be submitted. When resistor style RP05, RP06, and RP07 (see 3.1) are submitted, four additional
sample units without an electrical off position with the highest nominal total resistance value for which qualification is
sought shall also be submitted. To receive qualification of the locking bushing type resistors when standard bushing
type resistors are submitted, four additional sample units of locking bushing type resistors in the same style and
without electrical off position shall be submitted. These sample units shall consist of two with the highest nominal
total resistance value for which qualification is sought and two with the applicable nominal total resistance value
specified in table A-I. One additional sample unit of each style shall be submitted to permit substitution for the
TABLE A-I. Nominal total resistance
