NFPA 701:2004&2009是美国消防协会公布的关于阻燃织物和薄膜材料燃烧试验的标准。该标准在美国具有广泛的应用，适用于公共场所的窗帘，幕布等不要求耐水的悬挂织物。测试采用垂直燃烧方式进行，根据产品克重是否超过700g/m2和产品是否进行表面涂覆将产品测试具体分为两类，详见如下：
Method 1：
Scope：（1）Table Skirts
(2) Table Linens
(3) Display booth separators
(4) Textile wall hangings
Not apply to the specimens having an areal density greater than 700g/m2 (21 oz/yd2)
Not apply to the Vinyl-coated fabric.

Method 2:
Apply to the specimens having an areal density greater than 700g/m2
(21 oz/yd2)
Apply to the Vinyl-coated fabric.
Apply to the plastic films.

If the sample is claimed to durability to cleaning or weathering, then Original sample and the cleaned or weathered sample should be tested for flame propagation.

Method 1:

initial
1.5m *full width
5 working days
After 5 washes
1.5m *full width
7 working days
After 3 dry cleanings
1.5m *full width
7 working days
After accelerated water leaching
1.5m *full width

Specimen: 400*150mm *10 pcs
The specimen is vertically hanged. The specified gas flame shall be applied to the center of the lower edge of the specimen for 45 seconds.

Criteria:

(1) The fragments and residues that fall to the floor of the test chamber shall not continue to burn for more than an average of 2 seconds.
(2) The average weight loss of the 10 specimens in a sample shall be 40 percent or less.

Method 2:

8 working days

Specimen: Flat sheet : 125*1200mm * 10 pcs

Foldable: 610 *1200mm *4 pcs

Fail 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, the material shall be recorded as having failed the test.
(3)
When the char length of any single flat specimen exceeds 435mm, the material shall be recorded as having failed the test.
(4)
The fragments and residues that fall to the floor of the test chamber shall not continue to burn for more than 2 seconds.
