Table 1: —Minimum Design and Test Factors for Metallic Structures

• Structure has to be assessed to prevent detrimental yielding during its design service life, acceptance, or proof testing. ** Propellant tanks and SRM cases only.

The strength qualification requirements under a protoflight verification approach may be satisfied with a dedicated flight-like qualification unit developed for strength testing but not intended to be used as a flight unit. For this type of strength qualification program, workmanship verification is required for the first flight build as specified in 4.2.1b.
