This device class designator shall be a single letter identifying
9、 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 Device performance documentation K Highest re
10、liability class available. This level is intended for use in space applications. H Standard military quality class level. This level is intended for use in applications where non-space high reliability devices are required. G Reduced testing version of the standard military quality class. This level
11、 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). E Designates devices which are based upon one of the
12、 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 system performance. D
