I'd avoid these straw men, trust your customers to understand risk management.

Great, I'd love to see this risk modeling. Which sets of components would need to fail in order for a sample to be destroyed? Which components have failed? How often? Are the failures correlated?

What legal risks exist for the customer in your industry? When things go wrong in that way, how does it happen?

Do samples degrade over time? How fast? What is their viability rate?
