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.升級(jí)試驗(yàn)項(xiàng)目、為法及要求一般按表2 中的規(guī)定，或按航天器要求，但不能少于表2的項(xiàng)目。非另有規(guī)定，升級(jí)試驗(yàn)應(yīng)針對(duì)檢驗(yàn)批百分之百進(jìn)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.

2.一般情況下，密封器件在老煉試驗(yàn)之前，在每個(gè)檢驗(yàn)批中抽取2只樣品進(jìn)行DPA；篩選試驗(yàn)后從合格品中抽取1只樣品進(jìn)行DPA。DPA項(xiàng)目分別按表4的規(guī)定。如果進(jìn)行CA分析的試驗(yàn)包括DPA試驗(yàn)項(xiàng)目，同檢驗(yàn)批DPA可不重復(fù)進(jìn)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.
