I don't think any company explicitly claims their implementation handles X failure scenarios, certainly not in the EULA or license. You could possibly pick apart their documentation, but I think the warranty clause in most licenses would cover the product. This may not apply to regulated products dealing with health/safety/defense, and IANAL. Either way, best to assume most companies are lying through their teeth about any feature until you or someone you trust has validated it.
