1.2.3 Device class designator. This device class designator shall be a single letter identifying the product assurance level.
All levels are defined by the requirements of MIL-PRF-38534 and require QML Certification as well as qualification (Class H, K,
and E) or QML Listing (Class G and D). The product assurance levels are as follows:
Device class
K
H
G
Device performance documentation
Highest reliability class available. This level is intended for use in space
applications.
Standard military quality class level. This level is intended for use in applications
where non-space high reliability devices are required.
Reduced testing version of the standard military quality class. This level uses the
Class H screening and In-Process Inspections with a possible limited temperature
range, manufacturer specified incoming flow, and the manufacturer guarantees (but
may not test) periodic and conformance inspections (Group A, B, C and D).
1/ Due to the nature of the 4 transistor design of the die in these device types, topologically pure testing is important,
particularly for high reliability applications. The device manufacturer should be consulted concerning their testing
methods and algorithms.

Designates devices which are based upon one of the other classes (K, H, or G)
with exception(s) taken to the requirements of that class. These exception(s) must
be specified in the device acquisition document; therefore the acquisition document
should be reviewed to ensure that the exception(s) taken will not adversely affect
