All of the components of the fire door assembly must bear a listing agencies label (with the exception of ball-bearing hinges which meet the basic build requirements of ANSI 156.2 and NFPA 80) to ensure the components have been tested to meet the fire rating requirements.
EN 16034 is a set of European standards which specify the technical performance characteristics for fire resistant and smoke control products, such as fire doors. Compliance with this standard requires to fulfill the requirements of the Construction Product Regulation [1] for construction products (short CPR).
UL published its first standard, "Tin Clad Fire Doors", in 1903. In 1906, UL established a Label Service for certain product categories that require more frequent inspections. Products that passed UL's testing and regular inspections were given a UL label, which eventually evolved into the UL Mark.
The organization was founded in 1989 [2] by a group of window and door industry professionals in response to mounting pressure from local and national governments to standardize energy efficiency ratings for windows and doors. Before NFRC standardized energy efficiency ratings, each manufacturer developed their own methods.
Components and systems subject to certification fire testing include fire rated walls and floors, closures within them such as windows, fire doors, fire dampers, structural steel, and fire stops. Fire tests are conducted both on active fire protection and on passive fire protection items. There are full-scale, small-scale and bench-scale tests.
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.
