MIL-R-5757J
6.1.1 Contact rating. The contact ratings of relays covered by this specification are based on load endurance tests which establish the relay capability to switch rated loads. For the purposes of this specification, contact load ratings are defined as follows:
a. Low level: 10 µA at 50 mV to 10 mA at 6 V.
b. Intermediate: 10 mA at 6 V to 100 mA at 28 V. c. High level: Above 100 mA at 28 V.
6.2 Acquisition requirements. Acquisition documents must specify the following:
a. Title, number, and date of the specification, date of the applicable specification sheet, and the PIN. b. Packaging requirements (see 5.1).
c. Special or additional identification marking requirements.
6.2.1 Manufacturer provided services. The manufacturer may provide the following optional value added services when specified in the order:
a. Hot solder dipping of terminals (see 3.4.7.5). b. Shortening of wire leads (see 3.4.7.2).
6.3 Qualification. With respect to products requiring qualification, awards will be made only for products which are, at the time of award of contract, qualified for inclusion in Qualified Products List QPL No. 5757 whether or not such products have actually been so listed by that date. The attention of the contractors is called to these requirements, and manufacturers are urged to arrange to have the products that they propose to offer to the Federal Government tested for qualification in order that they may be eligible to be awarded contracts or orders for the products covered

6.4 Shelf life. Relays conforming to this specification should be designed for a minimum of 7 years shelf life, following which the relays should be satisfactory for intended use without further conditioning.
6.5 Sealing. The following procedure is suggested as a guide; however, every effort should be made to utilize the most effective procedure consistent with the state of the art.
a. Evacuate to less than 200 microns.
b. Heat to maximum rated ambient temperature with continued evacuation (see 3.1).
c. Maintain heat and vacuum for 12 hours or longer, continuing the treatment until a maximum pressure of 80 microns is reached.
d. Turn off heaters and maintain pressure for 4 hours.
e. Close evacuation valve and fill chamber with the desired pressurizing gas. f. Seal relay before removing from chamber.
