NFPA 701 Fire test to textiles and films- Test Requirements

Test Method 1

1) Fragments or residues of specimens that fall to the floor of the test chamber shall not continue to burn for more than an average of 2 seconds per specimen for the sample of 10 specimens.

2) The average weight loss of the 10 specimens in a sample shall be 40 percent or less.

 

Test Method 2

1. Performance Criteria.

 

1) When any specimen continues flaming for more than 2 seconds after the test flame is removed from contact with the specimen, the material shall be recorded as having failed the test.

 

2) When the length of char of any individual folded specimen exceeds 1050 mm (41.3 in.), the material shall be recorded as having failed the test.

3) When the char length of any single flat specimen exceeds 435 mm (17.1 in.), the material shall be recorded as having failed the test.

4)When at any time during or after the application of the test flame, any portions or residues of the material being tested break or drip from the specimen fall to the floor of the test apparatus, and continue burning for more than 2 seconds after reaching the floor of the test apparatus, the material shall be recorded as having failed the test.

 

2. Retest.

1) In the event that only one of the four folded specimens does not meet the criteria of Section 15.1, two new specimens cut in the same direction as the one that failed shall be tested.

2) If both of the new folded specimens meet all of the criteria, the material shall be recorded as having passed this test.

3) In the event that only one of the 10 flat specimens does not meet the criteria of Section 15.1, five new specimens cut in the same direction as the one that failed shall be tested.

4) If all five of the new flat specimens meet all of the criteria, the material shall be recorded as having passed this test.
