Icom Quality and Reliability IMMERSION METHOD 512.4 The immersion test is performed to determine if radios can withstand immersion or partial immersion in water and operate as required during or following immersion. • Procedure I - Immersion. Procedure I (Immersion) primarily addresses leakage during immersion of encased radios. Depth of immersion is 1m. Duration of immersion is 30-minutes VIBRATION METHOD 514.5 Develop radios to function in and withstand the vibration exposures of a life cycle including synergistic effects of other environmental factors, radios duty cycle, and maintenance. Although verify that radios will function in and withstand the vibration exposures of a life cycle. • Procedure I - General vibration. Use Procedure I for those cases where a test item is secured to a vibration exciter and vibration is applied to the test item at the fixture/test item interface. Steady state or transient vibration may be applied as appropriate. SHOCK METHOD 516.5 Shock tests are performed to provide a degree of confidence that radios can physically and functionally withstand the relatively infrequent, non-repetitive shocks encountered in handling, transportation, and service environments, and determine the radio's fragility level, in order that packaging may be designed to protect the radio's physical and functional integrity. • Procedure I - Functional Shock. Procedure I is intended to test radios (including mechanical, electrical, hydraulic, and electronic) in its functional mode and to assess the physical integrity, continuity and functionality of the radios to shock. In general, the radios is required to function during the shock and to survive without damage to shocks representative of those that may be encountered during operational service. • Procedure IV - Transit Drop. Procedure IV is intended for radios either outside of or within its transit or combination case, or as prepared for field use (carried to a combat situation by man, truck, rail, etc.). This procedure is used to determine if the radios is capable of withstanding the shocks normally induced by loading and unloading when it is outside of its transit or combination case, or inside its transit or combination case. Such shocks are accidental, but may impair the functioning of the radios. Icom: High Quality, Exceptional Reliability, and Global Sustainability Immersion Test Vibration Test 12
