What Fire Rating Standards should EJS conform to?
There are several approved testing authorities. Some of the most widely accepted are: 1. BS-476 Parts 20 and 22: 1987 – Fire Tests on Building Materials and Structures. 2. UL-2079 – Standard for Tests for Fire Resistance of Building Joint Systems. In addition, joints employing rubber seals in below ground applications should incorporate *Vamac seals rather than the standard units normally supplied. *Vamac joints have been specifically designed for projects where a high degree of fire resistance and low toxic smoke emission is required. Such installations include underground rail terminals, basement levels of air terminals, hospitals and other areas where personnel (or passengers) work (or transit) below ground level. Vexcolt’s *Vamac synthetic rubber extrusions have been tested and approved to the latest London Underground Limited Engineering Standard E1042:A4 September 2000′ Engineering Standard for the fire safety performance of materials used underground’.
