Vorschlag ... sowie einige militärtechnische Waffenanwendungen mit mittleren Zuverlässigkeitsanforderungen (Stufe C, MIL-PRF-55681).

This is the full sentence: Applications for the MR series include audio equipment, motor controls for a wide variety of market segments, security monitoring, access control, network and communications products as well as some non-established reliability military weapons and armament applications.

Bernd, your explanation seems to fit! Do you have an idea for a translation

Bernd Runge Feb 7, 2011:

non-established reliability (non-ER) scheint der gesuchte Begriff zu sein. Gemäß US-Mil-Standard XY werden Bauteile in high reliability, ER und non-ER unterteilt.

4.6.1.2.1 Non-ER capacitors (C-level). The manufacturer shall establish and maintain an inspection system to verify that capacitors meet the capacitance, DF, IR (at 25°C), visual/mechanical, and solderability requirements. Inline
or process control may be part of such system. The inspection system shall also include criteria for lot rejection and corrective actions. The inspection system shall be verified under the overall MIL-STD-790 QPL system.
NOTE: Since the non-ER (C-level) is the ER design without the mandatory conformance inspection and FRL assessment, this product is still expected to meet the environmental qualification type requirements (e.g., moisture resistance, thermal shock, etc).

Da müsste man den ganzen Satz gesehen haben.
