Clarification of “Class III Not For Flight” label:
Note the "Class III Not for Flight’ decal applied to the grip. When an item returns from a mission, NASA inspects the equipment thoroughly. During this inspection they would looks for points of failure and either address them or *decommission the equipment.
An item may also be decommissioned if the equipment is made obsolete. When this decommissioning takes place, the NOT FOR FLIGHT decal would generally be applied and the unit would be taken out of service
