The NT Fire 017 fire test originates from NordTest which aims to develop innovation and standards between Nordic countries. It is a particularly well-known fire test and is considered something of an industry standard. The SP testing lab in Sweden is perhaps the most highly regarded lab which performs this test.
There are several different types of test within the NT Fire 017, depending on the type of contents the safe is meant to protect.
NT FIRE 017-60 Paper: The safe is heated in a furnace for 1 hour to 945° C. During this time, the internal temperature of the safe may not rise by more than 150° C. Safes in this category provide one hour of protection for paper by keeping temperatures below 177° C, the point at which paper chars or combusts.
NT FIRE 017-90 Paper: The safe is heated to 1006° C over 90 minutes. During this time, its internal temperature may not increase by more than 150° C. Safes in this category provide 90 minutes of protection for paper by keeping temperatures below 177° C, the point at which paper chars or combusts.
NT FIRE 017-120 Paper: The safe is heated to 1049° C for 2 hours. The internal temperature of the safe may not increase by more than 150° C in this time. Safes in this category provide two hours of protection for paper by keeping temperatures below 177° C, the point at which paper chars or combusts.
