When we see “tested under laboratory conditions”, we often assume real-world conditions will lead to faster degradation of a product.

Why would you assume that? You're going to test a range of things, but you're likely most interested in the best and worst case. Lab conditions just means consistent conditions.

Because if a company is paying a lab to test its product for marketing numbers than there is a significant incentive for both the lab and marketing department to fudge the results upwards.
