MIL-R-193090
3.5.1 0ielectric strength. The relay shall withstand the application of an ac voltage of 700 volts rms at 60 Hz for a period of one minute between any relay terminal and the relay case, and between any coil terminal and any contact terminal without damage, arcing, or breakdown (see 4.3.4.1).
3.5.2 Insulation resistance. The insulation resistance between any terminal of the relay and the case, and between any coil terminal and any contact terminal, shall be not less than 100 megohms (see 4.3.4.2).
3.5.3 Contact resistance. The resistance across contacts 3 and 4 and contacts 7 and 8 when the relay coil is deenergized, and across contacts 2 and 4 and across contacts 6 and 8 when the relay coil is energized and the contacts are carrying rated current (see 3.4.5.1.1), shall not exceed 0.05 ohm (see 4.3.4.3).
3.5.4 Contact bounce. The relay shall not exhibit any characteristics of contact bounce or chatter three milliseconds after the contacts make or break (see 4.3.4.4).
3.5.5 Coil resistance. The coil resistance of the relay shall be 1,000 ohms ± 10 percent, when measured at a temperature of 68°F (20°C) (see 4.3.4.5).
3.5.6 Coil current.
3.5.6.1 Operate. The maximum current at which contact 4 transfers from contact 3 to contact 2 and contact 8 transfers from contact 7 to contact 6 shall be not greater than 6.3 mA. Under the conditions of vibration (see 3.6.1.2) and acceleration (see 3.6.3) contact 4 shall remain closed to contact 3 and contact 7 shall remain closed to contact 6 with a coil current increasing up to, but not exceeding 5.0 mA (see 4.3.4.6.1).
3.5.6.2 Release. The minimum current at which contact 4 transfers from contact 2 to contact 3 and contact 8 transfers from contact 6 to contact 7 shall be not less than 6.3 mA. Under the conditions of vibration (see 3.6.1.2) and acceleration (see 3.6.3) contact 4 shall remain closed to contact 2 and contact 8 shall remain closed to contact 6 with a coil current decreasing to, but not below, 3.15 mA (see 4.3.4.6.2).
3.5.7 Sensitivity (see 4.3.4.7).
3.5.7.1 Operate. The operating sensitivity shall be a nominal 40 mW.
3.5.7.2 Release. The release sensitivity shall be a nominal 5 mW.
3.5.8 Operating and releasing time.
3.5.8.1 Operating. The operating time, when the coil of the relay is energized from a nominal 10 V dc source, shall be not greater than 30 ms.
3.5.8.2 Releasing. The release time, when an energized coil is deenergized, shall be not greater than 10 ms.
3.5.9 Operating life. The relay shall be capable of meeting the performance and product characteristics specified herein after experiencing 100,000 contact transfers under the environmental conditions described in 4.3.1.
3.6 Environmental requirements. The relay shall meet the other applicable requirements of this specification during or after the tests defined or specified in 4.4.
3.6.1 Vibration. The relay shall meet the following vibration requirements.
3.6.1.1 Vibration, nonoperating. The relay shall show no damage and shall meet all the performance requirements and product characteristics of this specification after being tested as in 4.4.1.2.
3.6.1.2 Vibration, operating. The relay shall show no damage and shall meet all the performance requirements and product characteristics of this specification during and after the test specified in 4.4.1.3.
3.6.1.3 Vibration, transportation. The relay shall show no damage and shall meet all the performance requirements and product characteristics of this specification after being tested as in 4.4.1.4.
