Verification:

Periodic inspection:  Groups B and C inspections are not applicable. Group A.

a.  Group A1:  Run-in (applicable to -003 low level relays only).  This subgroup may be waived at the discretion of the qualifying activity if fully tested MIL-PRF-39016/6 relays are used internally.

b.  Group A2:  100 percent.

c.  Dielectric withstanding voltage:

(1)  Tests to be conducted at sea level rating only.

(2)  Duration of application:  5-10 seconds at a 10 percent increase in the dielectric strength voltage. Qualification:  See table I or table II as applicable.
