REQUIREMENTS 3.1 Item requirements. The individual item requirements shall be
18、in accordance with MIL-PRF-38535, appendix A for non-JAN class level B devices and as specified herein. Product built to this drawing that is produced by a Qualified Manufacturer Listing (QML) certified and qualified manufacturer or a manufacturer who has been granted transitional certification to M
19、IL-PRF-38535 may be processed as QML product in accordance with the manufacturers approved program plan and qualifying activity approval in accordance with MIL-PRF-38535. This QML flow as documented in the Quality Management (QM) plan may make modifications to the requirements herein. These modifica
20、tions shall not affect form, fit, or function of the device. These modifications shall not affect the PIN as described herein. A “Q“ or “QML“ certification mark in accordance with MIL-PRF-38535 is required to identify when the QML flow option is used. 3.2 Design, construction, and physical dimension
21、s. The design, construction, and physical dimensions shall be as specified in MIL-PRF-38535, appendix A and herein. 3.2.1 Case outlines.
