Vibration step stress shall begin at a chamber set point of 10Grms, as measured over a 2Hz to 2000Hz bandwidth and increases in 5Grms increments upon completion of a 15-minute dwell time and functional test. The vibration step stress is continued until the operational limit of the sample is determined or the chamber maximum (60Grms) is achieved. Attempt to determine destruct limit by continuing to step vibration up by 5Grms increments. Dwell for 15 minutes at each level, and then return to the operating limit. When the test is complete let the boards reach ambient conditions and retest the boards. Visually inspect the boards for missing and loose components. Log all test resust.

从振动一步一室压力设置点10Grms在2Hz计算,对2000Hz 5Grms增加带宽,提高了15竣工时间和功能测试。住压力是振动步骤直到运作极限的样品测定或商会(60Grms)。为了确定破坏极限,继续5Grms振动的一步。住了15分钟,然后返回操作的限制。测试完成让板及环境条件和样品。视力检查和松散的部件上失踪。记录所有的测试resust。
