MIL-R-10509J
4.6.4.2 Disposition of sample units. Sample units which have passed all the group B inspection may be delivered on the contract or purchase order, at the option of the supplier, provided the resistor terminals were not soldered during any of the tests.
4.6.5 Inspection of packaging. The sampling and inspection of the preservation, packaging, and container marking shall be in accordance with the requirements of section 5.
4.7 Methods of examinations and tests.
4.7.1 Visual and mechanical examination. Resistors shall be examined to verify that the materials, design, construction, physical dimensions, marking, and workmanship are in accordance with the applicable requirements (see 3.1, 3.3 to 3.4.1 inclusive, and 3.24 to 3.26 inclusive).
4.7.2 DC resistance. (see 3.7). Resistors shall be tested in accordance with method 303 of
MIL-STD-202. The following details and exception shall apply:
a. Measuring apparatus: Different types of measuring test equipment (multimeters, bridges, or equivalent) are permitted to be used on the initial and final readings of this test, provided the equipment is the same style, model, or if it can be shown that the performance of the equipment is equivalent or better.
b. Test voltage: Measurements of resistance shall be made by using the test voltages specified in table IX. The test voltage chosen, whether it is the maximum or a lower voltage which would still provide the sensitivity required, shall be applied across the terminals of the resistor. This same voltage shall be used whenever a subsequent resistance measurement is made.

c. Temperature: The dc resistance test specified in group I of table V shall performed at 25°C ±2°C.
For all other tests, unless otherwise specified herein, the temperature at which subsequent and
final measurements are made in each test shall be within ±2°C of the temperature at which initial measurement was made.
4.7.3 Seal (applicable only to hermetically sealed resistors) (see 3.8). Resistors shall be tested in accordance with method 112 of MIL-STD-202. The following details and exceptions shall apply:
a. Test condition letter: A.
b. After test: Resistors shall be cleaned in alcohol, or a degreaser, and allowed to dry thoroughly.
