NFPA 701 - New fire lab equipment

Centexbel performs fire tests on curtains destined for the USA


NFPA 701 - Fire Tests for flame Propagation of Textiles and Films

NFPA 701 is a method to determine the burning behaviour of curtains and has been performed in the USA since many years. In the meantime, the method has been drastically adapted.
The standard includes a small-scale and a large-scale test. The largest demand is for the small-scale test (method 1).

Centexbel runs this test for many years, and now we have purchased the most recent equipment to keep up with the changes.

NFPA 701 (Small Scale) testing measures the ignition resistance of a fabric after it is exposed to a flame for 12 seconds. The flame, char length, and flaming residue are recorded. The fabric will pass the test if all samples meet the following criteria:

  1. an after flame of less than 2.0 seconds
  2. a char length of less than 6.5”
  3. the specimen does not continue to flame after reaching the floor of the test chamber
