Differentiations of Flame Retardancy Performance

Fabric that is certified as FR has been topically treated in an immersion process with a chemical fire retardant after the fabric has been woven. All cottons and other natural fibers certified as flame retardant are FR topically treated. Some synthetic fabrics are also topically treated. Because the treatment is topical, it will wear out in time, and repeated cleanings will cause the flame retardancy to dissolve sooner. Most flameproofing chemicals are water soluble and will lso dissipate through dry cleaning.
Draperies made from FR fabrics should be re-tested periodically for flame retardancy, as retreatment may be required. For this reason, “FR” flame retardancy is certified for only one year. A Certificate of Flame Retardancy is furnished to customers upon request.
Fabric that has been certified as “IFR” or “PFR” has been woven from fibers that are noncombustible for the life of the fabric. For this reason, the fire retardancy of “IFR” and “PFR” fabrics will last for the life of the fabric and will not dissipate after cleaning. A Certificate of Fire Retardancy is furnished upon request.
Fabric labeled “NFR” is not. If “CBFP” is indicated for a fabric, that fabric can be treated for fire retardancy. Such treatment would include topical treatment in an immersion process, making the fabric “FR.” Some synthetics can be made fire retardant. IF “CNFR” is indicated for a fabric, that fabric cannot be treated for fire retardancy and, as such, should not be used in public venues. Among the types of fabrics that cannot be made fire retardant are certain synthetic and/or metallic fabrics.

“IFR” – Inherently Fire Retardant (aka Inherently Flame Retardant)
“PFR” – Permanently Fire Retardant (aka Permanently Flame Retardant)

“NFR” – Not Fire Retardant
“CBFR” – Can Be Made Fire Retardant
“CNFR” – Cannot Be Made Fire Retardant
