Fire retardant cables

Fire retardant cables are used in fire safety, fire detection and fire alarm systems and other applications where specifications require cables with specific performance in the event of a fire.

 

Flame retardant cables are designed with the objective of limiting the generation and spread of fire and smoke.

The below list is typical of the standards to which apply to fire retardant cables

 -        EN 50267-2-1:Common test method for cables under fire conditions- tests on gases evolved during combustion of materials from cables - procedures - Determination of the amount of halogen acid gas

-        EN 50267-2-3:Common test methods for cables under fire conditions - Tests on gases evolved during combustion of materials from cables - Procedure 2-3: Procedures - Determination of degree of acidity of gases for cables by determination of the weighted average of pH and conductivity

-        EN 60332-3: Tests on electric and optical fibre cables under fire conditions - Part 3: Test for vertical flame spread of vertically mounted bunched wires or cables
