9、applies for any combination of operating temperature and voltage. 2/ Recycle time is defined as the maximum time that power must be removed from the input terminals to assure that the next timing cycle will be completed within the specified timing tolerance. (Units can be recycled during timing or a
10、fter time-out.)

14、dition, relays shall be marked with the ESDS identifier as specified in MIL-STD-1285. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-R-83726/22F 5 ESDS protection program: An ESDS protection program shall be implemented within 6 months of the da
15、te of revision C to this document. The manufacturer shall establish and maintain an ESD control program in accordance with MIL-STD-1686 for mission critical equipment. Evidence of such compliance shall be verified by the qualifying activity of this specification as a prerequisite for qualification a
16、nd continued qualification. This program shall be documented by an ESD control plan which must be under document control. As a minimum, this plan must address the identification of ESDS sub-components and end items, facilities, training, design protection, handling procedures, marking, cleaning, pre
17、servation, packaging, and quality assurance. A model ESD control program is available from the qualifying activity and may be used as a guideline. Further guidance for ESD control is available from the EOS/ESD Association and the Electronics Industry Association (EIA). This requirement is applicable
18、 to all manufacturers who handle ESDS component parts and materials in the relay manufacturing or testing process. This requirement is not limited to manufacturers qualifying ESDS end items. ESDS verification: As a part of qualification or qualification after redesign, ESD testing shall be done in a
19、ccordance with method 3013 of MIL-STD-883 modified to test at 16,000 volts. Testing at lower voltage levels is not required. This testing shall be accomplished as part of the group III for qualification inspection as as part of the group C inspection. ESDS preservation and packaging: Relays shall be
20、 preserved and packaged in such a manner as to ensure that the integrity of ESD sensitive relays is not diminished. ESD sensitive relays shall be preserved and packaged in accordance with the requirements of MIL-STD-1686. Part or Identifying Number (PIN): Consists of the prefix M83726/22-, a four-di
21、git dash number denoting the length of one complete cycle (expressed in milliseconds), and a suffix letter W for relays with less stringent EMI requirements and a suffix letter A for relays with more stringent EMI requirements. M 83726/22 - 1001 W or A Military designator Specification sheet Dash nu
22、mber Suffix letter Examples The first three digits of the dash number are significant; the fourth digit is the number of zeros to follow the first three digits. The time delay is expressed in milliseconds and converted to seconds. M83726/22 - 1000W - Time delay repeat cycle 1 per 100 ms for printed-
23、circuit type mounting. M83726/22 - 2500A - Time delay repeat cycle 4 per second with flange mounting. Conformance inspection: Performance of group B and group C testing is not applicable.
