Fire Retardant Testing

Firefree's coatings have passed the fire industry's most stringent tests for fire retardants. The first level of fire retardant testing is the ASTM E 84 (NFPA 255, UL 723) Steiner Tunnel Test which measures horizontal flame spread and smoke development over a 10 to 30 minute test period.

As the industry's understanding of fire grew, it became apparent that the greatest fire spread is vertical flame spread. As the initial materials burn, the flames will travel vertically and gases will collect at the ceiling. These gases ignite causing flashover, a fireball explosion that will burst into other parts of the structure.

Firefree 88 was the first coating to pass the most comprehensive and stringent, next generation, fire retardant tests: (i) the vertical flame spread/flashover (UBC 26-3/FM 4880/UBC 8-2 room corner tests) and (ii) the Factory Mutual 4975 hydrocarbon ceiling test, all of which have passed on a wide variety of materials including wood, cellulose ceiling tiles and gypsum board, depending on which Firefree coating needed to be used for a specific assembly.

ASTM E-84 (NFPA 255, UL723) Steiner Tunnel Test

The ASTM E-84 test is used as a means of measuring flame spread and smoke over a horizontal surface for a period of 10 minutes with an 80kw energy source, resulting in either a class A, B or C rating. Firefree Class A and Firefree 88 have successfully tested to meet all code requirements accepted in accordance with ASTM E-84.

FIREFREE CLASS A

ASTM E84 (NFPA 255, UL 723)

QAI Laboratories, IAS accredited fire testing laboratory, and CALFIIRE Approved Testing Laboratory

Results:

Firefree Class A achieved a testing result for flame spread index of ≤25, with a minimal thickness of 6 mils (.006 inch) dry application.

Firefree Class A also meets the requirement for fire and smoke characteristics used in plenum spaces with a minimal thickness of 10 mils (.010 inch) because of its smoke index reading of 30 (less than 50).

ASTM E84 (NFPA 255, UL 723) – EXTENDED 30 MINUTE

QAI Laboratories, IAS accredited fire testing laboratory and CALFIRE Approved Testing Laboratory

Test Criteria:

Achieve a listed flame spread index of 25 or less and show no evidence of significant progressive combustion when the test is continued for an additional 20-minute period.

Results:

Firefree Class A achieved a testing result for flame spread index of ZERO (0) and smoke development index of ZERO (0), with a minimal thickness of 20 mils (.020inch) dry application.

In addition to the testing performed, although it is not required by the test standard, char damage measurements were taken to effectively show the high performance level of the coating. Based on the results obtained from the 30 minute extended test, the wood materials tested showed minimal char damage, showing FFA's ability to assist in maintaining the structural integrity of the wood materials in a fire situation.

British Standard 476 Part 6 & 7

This test determines the performance of a product when it is subjected to the conditions of the test specified in BS 476 Part 6 and 7 "Fire tests on building materials and structures, method for fire propagation for products".

BS 476: Part 6: Specifies a method of test, the result being expressed as a fire propagation index that provides a comparative measure of the contribution to the growth of fire made by an essentially flat material, composite or assembly. It is primarily intended for the assessment of the performance of internal wall and ceiling.
BS 476: Part 7: Specifies a method of test for measuring the lateral spread of flame along the surface of a specimen of a product orientated in the vertical position, and a classification system based on the rate and extent of flame spread. It provides data suitable for comparing the performances of essentially flat materials, composites, or assemblies, which are used primarily as the exposed surfaces of walls or ceilings.

UBC Standard No. 26-3, Room Fire Test Standard for Interior of Foam Plastic Systems (FM 4880/ NFPA 286)

This test was originally designed to evaluate a product's ability to reduce or eliminate fuel contribution, flame spread and prevention of flashover within a room. The test is performed inside an 8'x12' room with 8' ceilings using an ignition source consisting of a 30-pound wood crib. The walls and ceiling of each room was paneled with plywood, which is commonly found in building structures, as many buildings have wood paneling in their interiors. Additionally, wood is highly combustible, thus making the test a worst-case scenario.

This test standard is designed to evaluate a product's ability to reduce or eliminate fuel contribution, flame spread and prevention of flashover of foam products within a room. The test is performed inside an 8'x 12' room with 8' ceilings using an ignition source consisting of a gas powered sand burner generating a 50kw heat source for 5 minutes and 160kw for 10 minutes. The walls and ceiling of each room are coated with 3 inches of foam on the walls and 51/2 inches of foam on the ceiling, with a foam coating thickness variation of plus or minus ½ inch. This stringent test standard has been adopted by NFPA as a result of the dramatic foam fires that have occurred and continue to occur with the increased use of foam products in building structures.

Firefree 88 has been tested in accordance to Room Corner Test on the following substrates:

UBC 8-2, Room Corner Test

This test was originally designed to evaluate a product's ability to reduce or eliminate fuel contribution, flame spread and prevention of flashover within a room. The test is performed inside an 8'x12' room with 8' ceilings using an ignition source consisting of a gas powered sand burner generating a 40kw heat source for 5 minutes and 150kw for 10 minutes. Firefree 88 was tested on numerous highly volatile wood substrates shown below and, in each case, the test showed no material flame spread, smoke development or room flashover. We have tested at The University of California / Forest Laboratories on the following substrates:.

5/8" Douglas fir
1/2" Masonite board siding
Cedar shingles
1/4" Mahogany paneling
7/16" Oriented Strand Board siding

FM 4975 Hydrocarbon Ceiling Test

This test measures the rate at which fire will travel on a ceiling and shows a product's ability to prevent smoke, flame spread and heat release across an expansive ceiling area such as would be found in a large industrial building. In the tests we used highly combustible substrates to show the product's ability to perform on other substrates, which are less combustible. To our knowledge, no other coating has ever passed this test for this range of substrates. The following substrates were tested at Factory Mutual Laboratories:

1x4 Douglas Fir T&G
1/2" cellulose ceiling ties
1/2" gypsum
