10. Gasket shall provide a reliable seal between the relay and mating socket that will meet the environmental, operational, and interface requirements of the relay with the mating socket. The gasket shall have shore
hardness 20 ±5, thickness .072 ±.008, recessed .047 ±.005 in to bracket. Gasket material according to AMS 3332
has been considered acceptable.
11. Gasket shall provide a reliable seal between the relay and mating socket that will meet the environmental, operational, and interface requirements of the relay with the mating socket. The gasket shall have shore hardness 20 ±5, thickness .062 ±.005 flush with bracket. Gasket material according to AMS 3332 has been
considered acceptable.
