This rating is the requirement in data safes and vault structures for protecting digital information on magnetic media or hard drives. Temperatures inside the protected chamber must be held below 125 °F (52 °C) for the time period specified, such as Class 125-2 Hour, with temperatures up to 2,000 °F (1,090 °C) outside the vault.
Also, test results for heat, smoke, and combustion product release from NFPA 286 are suitable for use as input into fire models for performance-based design, whereas results from NFPA 255 are not. [4] Flame spread rating number is not the rate at which the flame actually spreads along the surface and is not an indication of the fire resistance ...
NFPA 80 allows a maximum door undercut of 3/4 inch, however fire doors are tested with smaller clearances in accordance with NFPA 252. [6] Corridors have a fire rating of one hour or less, and the fire doors in them are required by code to have a fire rating of 1/2 or 1/3 hour, the intent of which is mainly to restrict smoke travel.

A more recent industrial standard is the European EN 13501-1 - Fire classification of construction products and building elements—which roughly replaces A2 with A2/B, B1 with C, B2 with D/E and B3 with F. B3 or F rated materials may not be used in building unless combined with another material that reduces the flammability of those materials.
A fire test is a means of determining whether fire protection products meet minimum performance criteria as set out in a building code or other applicable legislation. Successful tests in laboratories holding national accreditation for testing and certification result in the issuance of a certification listing .
"NFPA 704: Standard System for the Identification of the Hazards of Materials for Emergency Response" is a standard maintained by the U.S.-based National Fire Protection Association. First "tentatively adopted as a guide" in 1960, [ 1 ] and revised several times since then, it defines the " Safety Square " or " Fire Diamond " which is used to ...
The term fire-retardant as applied to organic (i.e., containing carbon) materials, is intended to refer to reduced fire hazard, as all will burn under certain circumstances. The tests used specified in building codes , such as NFPA 701, are more correctly flame resistance tests, which test a fabric's ability to resist ignition with the flame ...
Fire rating - Fire walls are constructed in such a way as to achieve a code-determined fire-resistance rating, thus forming part of a fire compartment's passive fire protection. Germany includes repeated impact force testing upon new fire wall systems. Other codes require impact resistance on a performance basis [6]
