ASTM E-136

If a material passes this test, it is non-combustible.

ASTM E-119

Hourly rating of a wall when exposed to fire. Deter­mines how long that the wall holds back heat and flames and maintains its structural integrity.

ASTM E-184

Hourly rating for a sealant system for a penetration through a fire-rated (ASTM E119) assembly.

ASTM E-84

Test measures how fast flames spread in a fire tun­nel lined with the tested material, compared to red oak, which is given a flame spread of 100. This test classifies materials as Class I, II, or III (or A, B, & C) See flame spread in the three rows below.

Class I or A

Flame spread less than or equal to 25

Class II or B

Flame spread 26 to 75

Class III or C

Flame spread 76 to 200

FM 4880 or UL-1040

Like ASTM E-84 except the fire burns in a 90-degree corner of a wall assembly containing the tested material. These tests are designed to closer approximate actual performance of a material installed in a typical building assembly. The flame spread and smoke developed ratings also relative to Class I, II, and III assemblies.

UL 1715

Like the tunnel test and corner test except the fire burns in a room with its wall and ceiling assembly containing the tested material. The flame spread and smoke developed ratings also relative to Class I, II, and III assemblies.

UL181

Duct materials, duct-closure systems, and duct sealants so labeled pass UL fire-resistance tests.
