The routine up-screening test consists of the up-screening test on sealing devices as shown in Table 2 and DPA test in Table 4. Details are as follows:

1.升级试验项目、为法及要求一般按表2 中的规定，或按航天器要求，但不能少于表2的项目。非另有规定，升级试验应针对检验批百分之百进行。

1.The up-screening test items, methods and requirements shall generally follow the specifications in Table 2; or follow the specific requirements on spacecraft, on the premise that the tests specified in Table 2 shall be conducted at a minimum. One hundred percent of the inspection lot shall be subject to the up-screening test, unless otherwise specified.

2.一般情况下，密封器件在老炼试验之前，在每个检验批中抽取2只样品进行DPA；筛选试验后从合格品中抽取1只样品进行DPA。DPA项目分别按表4的规定。如果进行CA分析的试验包括DPA试验项目，同检验批DPA可不重复进行。

2. Generally, before carrying out burn-in test on sealing devices, 2 samples should be selected from each inspection lot to conduct DPA; 1 sample should be selected from the qualified products upon the screening test is finished to conduct DPA. DPA items shall follow requirements in Table 4. In case the CA analysis test has already included DPA test items, DPA is no longer necessary for the same inspection lot.
