Commercial furniture fire ratings exist to slow the spread of fire, giving occupants time to evacuate. Regulations vary by country, building type, and occupancy level.
Non-compliant furniture can result in failed inspections, insurance issues, and potentially catastrophic liability in the event of a fire.

British Standard, widely used across Europe for commercial seating
US: CAL 117-2013
California standard, becoming de facto US commercial standard
EU: EN 1021-1/2
European standard for resistance to cigarettes and match flames
Maritime: IMO
International Maritime Organization standards for ships

How Furniture Achieves Fire Ratings
Inherently FR Fabrics
Fibers like modacrylic are fire-resistant by chemistry. Most durable option.
FR-Treated Fabrics
Chemical treatments applied to standard fabrics. May need retreating after cleaning.
FR Interliners
Fire-blocking layer between fabric and foam. Allows use of standard fabrics.
FR Foam
Modified foam that resists ignition. Used with FR fabric or interliner.

Specification Best Practices
Verify Local Requirements
Check with building control or fire authority before specifying.
Request Test Certificates
Suppliers should provide documentation proving compliance.
Specify Complete System
Fire rating requires the fabric-interliner-foam combination, not just fabric.
Plan for Cleaning
FR treatments can wash out. Use certified cleaning methods.
Frequently Asked Questions
Is FR furniture more expensive?
Typically 10-25% more than non-FR equivalents due to specialized materials and testing requirements.
Can I add FR treatment to existing furniture?
Yes, post-treatment is possible but less reliable than factory-applied treatments. Full reupholstery with FR materials is preferred.
Do fire ratings expire?
The rating doesn't expire, but treated fabrics may lose effectiveness after multiple cleanings. Retest or retreat after 5-7 years.
What happens if I use non-compliant furniture?
Failed inspections, insurance coverage issues, and potential criminal liability if fire causes injury or death.
