NFPA 701 (US) and European Fire Standards Differences

Fire Standards Distinction in Global Markets

In the US, NFPA 701 is required for curtains and similar hanging decorative materials [1].
A Class 1 certificate obtained in the EU does not substitute for NFPA 701 in the US [3].

NFPA 701 Test Methods and Acceptance Criteria

NFPA 701 includes two test methods [3].
Fabric weight and structural layer properties determine the selection of the test method [3].
Method 1 is applied to fabrics under 700 g/m² [3].
Method 2 is applied to heavier fabrics, vinyl-coated blackout fabrics and banners [3].
In the Method 1 test, 10 specimens measuring 150 x 400 mm are used [3].
To pass the test, flaming drip droplets falling to the floor of the test chamber must not burn for an average of more than 2 seconds [3].
