SCA1194
The shock spectrum shown in figure 5-8 represents the maximum expected
shock environment for the spacecraft adapter having a diameter of
the 1194 mm and a Marmon clamp separation system.
The shock spectrum corresponds to a tension of 30 kN in the spacecraft
adapter clampband and is defined for a location 12.7 cm (5 in) from the
separation plane on the spacecraft side of the interface.
The strength capability of the SCA1194 spacecraft adapter with this
clampband tension is given in section 6.1.
