NFPA 701 Test Range

Test method 1: suitable for table skirt, all kinds of curtains (curtain, stage curtain, shade cloth), tablecloth, decorative curtain, etc., it is suitable for testing single-layer fabric and multi-layer curtain, not suitable for samples with local density greater than 700g/m², for example, ethylene coated fabrics shall be tested with test method 2.

Test method 2: suitable for fabric with flat surface and area density greater than 700g/m², including multi-layer fabric, film, plastic curtain, etc., suitable for ethylene coated fabric, suitable for shade, tent, waterproof cloth and similar building fabric banner.

NFPA 701 Test Requirements

Test method 1

1 After removing the ignition source, the combustion time of the specimen shall not exceed 2 seconds.

2 The average mass loss of the sample burning shall not exceed 40 percent.

Test method 2

1 After removing the ignition source, the combustion time of any single sample shall not exceed 2 seconds.

2 The burning time of any single sample shall not exceed 2 seconds after dropping to the bottom of the test box when burning test.

3 The standard for the scorching length of the folded specimen depends on the type of specimen.

The NFPA 701-2 flammability tester is designed according to the requirements of test method 2, the general requirements and test steps of the test method are as follows.

General Requirements for Testing

1 Shear the test samples in the dispersed region of the material and cut the long edges along the longitudinal direction of the material.

2 For the unfolded samples, suspension naturally unfold. For the material to be folded up, fold the sample 4 times along longitudinally, and the size of each folding part is the same. For multilayer materials, they must be stitched together along four sides and longitudinal centerline by a needle.

3 Test samples should be baked in a furnace between 1 hour and 3 hours before testing

4 The flammability test should be carried out within 2 minutes after the sample is removed from the furnace.

Test step

1 Sample fixing: Folded parts of the folded sample shall be separated by 12±3 mm through the pole, the bottom center shall be 100±10 mm above the burner, and the bottom center of the plane sample shall be 100±10 mm above the burner. Use a fixed rod to pass through the sample and fix the sample with a clip.

2 Combustion test: igniting the burner, adjusting the flame state to 280±12mm, acting on the sample for 2 minutes, then evacuate the burner.

3 Record the burning time that after the material falling on the bottom of the test box, and the precision is 0.5s. Record the combustion time of the sample after the flame was removed, and the precision is 0.5s. Record the length of the charred part after all flames are extinguished.
