MIL-R-10509J

4.7.13 Life (see 3.18). Resistors shall be tested in accordance with method 108 of MIL-STD-202 . The following details and exceptions shall apply:

a. Method of mounting: Resistors shall be mounted and soldered on light weight terminals (see figure 4). The effective length of each terminal shall be 1 inch (25.4 mm). Resistors shall be so arranged that the temperature of any one resistor will not appreciably influence the temperature of any other resistor. There shall be no circulation of air over the resistors other than that caused by the heat of the resistors.
