Yep, although using angle grinders can possibly destroy what's inside. UL does have much more stringent standards. To quote the Wikipedia article on safes:
TL-15 - This is a combination-locked safe that offers limited protection against combinations of common mechanical and electrical tools. The safe will resist abuse for 15 minutes from tools such as hand tools, picking tools, mechanical or electric tools, grinding points, carbide drills and devices that apply pressure. While the UL 687 defines this as a "limited degree" of protection, that standard is used for commercial applications, and the TL-15 rating offers significantly better protection than many unrated safes.
