3.4 ENVIRONMENTAL VERIFICATION TESTING Customer must verify the compatibility of the Payload with the maximum predicted environments defined in Section 3.3. SpaceX will review the Customer’s chosen verification approach as well as test results during Mission integration to ensure Mission safety. 3.4.1 VERIFICATION APPROACH SpaceX allows two approaches to environmental verification testing Fleet Qualification and Flight Unit Protoqualification. Fleet Qualification A qualification unit is subjected to testing at qualification levels and every flight unit is tested to acceptance test levels. The acceptance tests must be performed at the fully integrated Payload assembly level, even if the Payload consists of multiple smaller Payload Constituents. Qualification can be performed at the Payload Constituent level. With this approach the qualification test validates the structural design while the acceptance tests) validate workmanship. Flight Unit Protoqualification: Each Payload flight unit is subjected to protoqualification test levels. Testing must be performed at the fully integrated Payload assembly level, even if the Payload consists of multiple smaller Payload Constituents. With this approach the protoqualification test validates both structural design and workmanship. Every Payload flying on a SpaceX Rideshare Mission must undergo either fleet qualification or flight unit protoqualification environmental verification testing. Payloads using a fleet qualification approach must submit evidence that the qualification unit is sufficiently similar to the flight unit. The environments verification approach in this section is designed to ensure the safety of Co-Payloads and the Launch Vehicle. Tests that are Advised are designed to ensure on-orbit health and functionality of the Payload but are not required in order to fly on a SpaceX Rideshare Mission. Tests that are Required must be completed by the Customer to ensure mission safety through Payload separation.
