UL TL-15 Safe Rating - Answers -Safes with an Underwriters Laboratory rating that
have passed standardized tests as defined in Underwriters Laboratory Standard 687
using tools and an expert group of safe-testing engineers. The safe rating label requires
that the safe be constructed of 1-inch solid steel or equivalent. The label means that the
safe has been tested for a net working time of 15 minutes using "common hand tools,
drills, punches hammers, and pressure applying devices." Net working time means that
when the tool comes off the safe, the clock stops. Engineers exercise more than 50
different types of attacks that have proven effective for safecracking.
UL TL-30 Safe Rating - Answers -This Underwriters Laboratory rating testing is
essentially the same as the TL-15 testing, except for the net working time. Testers get
30 minutes and a few more tools to help them gain access. Testing engineers usually
have a safe's manufacturing blueprints and can disassemble the safe before the test
begins to see how it works.
