Which load cases belong in our FR10 housing-tool comparison?

I have two proposals for transferring aluminium housings into inspection nests. Both quote the housing mass, but one has longer fingers and an adapter the other does not use. The hose fittings are absent from both totals. I cannot infer suitability from that comparison. More precisely, I need the tool suppliers and our integrator to agree what they are assessing: complete assemblies, held positions, movement and release. Should I request one worst-case load figure, or separate cases that remain tied to their actual geometry?
