The impact response spectrum refers to the maximum acceleration response curve generated by the
equipment under specified impact excitation. Impact response spectrum II means that the duration of
semi-sine impact response spectrum is 6 ms.
The static payload refers to the capability of the packed equipment to bear the weight from above in
the stipulated stack method.
