With two major caveat that make it way less practical: - those tests aren’t against ageing pans. To be the safest, you’d need to buy pans on a short cycle - chipping is still dangerous (physical degradation, including regular wear) Basically, there is a specific case (new, perfectly intact, low-regular temperatures only) where it’s probably safe, and everything else is potentially harmful.
