I have brass parts to quote on in work and one part specifies a
"Solder coating 300 to 500 microinches" that must pass a solderability test per mil-std-202, method 208. The other part calls for a Tin Solder Coating 0.0078 to 0.0127mm. I have no idea what this finish is, I know it is used in the electronics industry but we are mostly involved in the semi conductor and medical industries.
Any help would be appreciated.

The solder coating you may be looking for should be covered under MIL-T-10727
(ASTM B545 [affil. link to spec at Techstreet]
) or AMSP81728.
