- 3.4.6 QUALIFICATION - NO TEST CONSIDERATIONS
| 3.4.5 FUNCTIONAL TESTING REQUIREMENTS For all Payloads, separation detection circuits must be functionally verified before and after dynamic tests to ensure that a Payload does not inadvertently activate during ascent. Subject to SpaceX review, it is acceptable for this test to be coupled with the required vibration tests referenced in Table 3-15. 3.4.6 QUALIFICATION - NO TEST CONSIDERATIONS Static load qualification requirements maybe met in the absence of testing only in the cases where ALL of the following conditions are met and approval is formally granted following a pretest SpaceX review. The structure is entirely metallic and there are no fiber-reinforced or bonded components in the primary load path The structural design has simple load paths and the failure modes are well-defined The structure is similar in configuration and load conditions to a previously test-verified unit with good post- test correlation to models Development and/or component testing has been performed on critical and difficult-to-analyze elements of the structure and good correlation has been demonstrated In cases where approval is granted, positive structural margins must be analytically demonstrated to the allowable ultimate load at 2.0 times the limit load and the allowable yield load at 1.6 times the limit load. For approval to be granted, the Customer must provide rationale as to how all four no-test conditions are met at the time the request is made.
