  The PIP-II project's LB650 cavities could potentially be vulnerable to
mechanical deformation because of the geometric shape of the cavity due to
reduced beta. The mechanical property of the niobium half-cell was measured
following various heat treatments. The 5-cell cavities were tested in a
controlled drop test fashion and the real-world road test. The result showed
that the 900 $\deg$C heat treatment was compatible with cavity handling and
transportation during production. The test provides the bases of the
transportation specification and shipping container design guidelines.
