MIL-R-19365 Resistor, Adjustable, Wirewound, PowerThis specification covers power, adjustable, wirewound, resistors for use in electrical, electronic, communication, and associated equipment. These resistors have a resistance range of 1 ohm to 15,000 ohms, inclusive, and a resistance tolerance of ┬▒5 percent. The power ratings cover a range of 11 watts to 210 watts, inclusive. These power ratings are applicable only when the maximum resistance is engaged in the circuit. When only a portion of the resistance element is engaged, the power rating is reduced in approximately the same proportion as the resistance.

APPENDIX A

PROCEDURE FOR QUALIFICATION INSPECTION

A.1.  SCOPE

A.1.1  Scope.  This appendix details the procedure for submission of sample, with 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 appendix. A.3.  SUBMISSION

A.3.1  Sample.  A sample consisting of 12 coated or enclosed sample units, of the styles specified in column 1 of table A-I of the highest resistance value and using a nominal diameter wire of .004 inch (0.10 mm), shall be submitted for each style for which qualification is sought.  If the same coating and material are not used, a separate submission shall be furnished for each coating and material for which qualification is sought.  Four uncoated or unenclosed sample units shall also be submitted in each style specified in column 1 of table A-I.  If enclosures are used in lieu of coatings, four enclosures shall also be furnished.  Sample units shall be submitted complete with supplementary insulation and mounting hardware normally used for mounting the resistors.  The submitted samples shall be representative of the supplier's normal production.

TABLE A-I.  Style qualification.

A.4.  EXTENT OF QUALIFICATION

A.4.1  Extent of qualification.  Qualification of a particular style and resistance value will qualify a range of resistance values from the smallest value listed in the style (see A.3.1) to the resistance value tested.  In addition, qualification of one style will be the basis for qualification of another style (or styles), as specified in table A-I.
