该试验适用于DMT/PMT验证时期的产品可靠性测试，建议采用一次抽样可靠性试验(Sequential Reliability Testing)。

一次抽样可靠性测试设计及评估方法：

• 首先确认产品Spec.规定的MTBF值及信赖度水平(1- α)

• 依照下列公式与测试计划给予的时间要求确定测试样品的数量及测试时间-The test applies to DMT/PMT verification during reliability testing, reliability testing suggested a sample (Sequential Reliability Testing). Reliability testing a sample design and evaluation methods: •　First, to confirm product Spec. MTBF value and reliability required level (1- α) •　Test Plan in accordance with the following formula and the time required to determine the number of test samples and testing time
