Long-term storage shall be as specified in paragraph A.4.5, Appendix A of JAXA-QTS2110.

4.5

Change to Tests and Inspectionsa) Insulation Resistance(Standard) Insulation resistance in accordance with test method 302 of MIL-STD-202
is specified as follows. “If the instrument reading indicates that an insulation resistancemeets the specified limit (2 min.), and is steady or increasing, the test may beterminated before the end of the specified period (2 min.)“(Shortening of test time) From the test result and verification result, it was verified thatthe instrument reading increases or become stable within 2 minutes from the start ofvoltage application. Therefore, when the above condition is met and the measurement
reaches the 10-times of 10 thousand MΩ as a minimum (which is more than 100thousand MΩ), the test may be terminated before 2-minute passes.
