Fire Tests

Testing of Contego’s intumescent paint is performed by the most recognized independent labs in the industry with each being ILAC audited, accredited and certified fire testing laboratories.  All tests apply to both Contego RFB and CON-RFB brands.

While Contego does a number of tests in its own laboratories and with foreign laboratories, the only tests posted on its Website are tests that meet these stringent standards.

Contego is the only intumescent latex paint manufacturer that uses triple redundant quality control analysis on random batches using spectroflouroscopic FTIR analysis to map the chemical signature.

There are other ways Contego goes beyond the testing activities of other fire retardant paint manufacturers. For example, all of its steel testing is done to nine stated standards simultaneously – UL, ULc, ASTM, NFPA, UBC, ANSI and CEN, ISO and BSS for the international markets served.  Also, Contego publishes each of these tests on the website in their entirety – not just a one paragraph summary.  Full photo documentation, whenever provided by the fire testing laboratory is also provided to its clients.

Contego can be found at UL.com as a Classified product. Contego includes UL-263, UL-723, ULc-S101, ULc-S102 as some of the many different standards to which it tests substrates.  Contego has been tested by UL and bears the UL mark as a Classified product; UL is an important part of Contego’s quality control program.

ASTM is the globally recognized leader in the development and delivery of international voluntary consensus standards as the actual basis for building code is typically from ASTM International (“ASTM”, formerly known as the American Society for Testing and Materials).  Today, some 12,000 ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade and build consumer confidence.

In April 2013, the Contego International passed the first of its expected European tests, the British Standard / European Standard BS EN 13501-1.  This is another flame spread and smoke production test similar to the standard in the U.S. offered by ASTM E-84.  The test utilized a very thin, one coat application of the HS paint to Oriented Strand Board (OSB), therefore requiring up to 50% less product than its competitors to achieve the same result. The result of this newest test is a B-s1,d0 rating, putting Contego in league with the highest rated passive fire barrier products in the world, and allows Contego to apply the CE mark to its label similar to the UL mark currently displayed.

All of Contego’s tests are performed by the finest and most recognized fire testing laboratories, all of which are ILAC audited, accredited, and certified. Contego is the only intumescent paint  manufacturer that uses triple redundant quality control analysis of batches using spectrofluoroscopic FTIR analysis to map the chemical signature.

Most of the tests you will find in the links below were performed by UL, Intertek, Materials Analytical Services, MAGI, and KTA. Contego is unique in that all its data, regardless of which laboratory tested its products or when, is highly consistent, contributing to its nearly universal acceptance for virtually any structural design.

UL-263/ASTM E119 “Full Scale Fire Test for Light Gauge Steel Decking, Concrete, and Beams”

Test Name: ASTM-E119/UL-263/UBC 7.1/NFPA 251/ANSI A2.19
Location: Intertek Laboratories
Test Date: 04.16.2009

This was a full-scale fire resistance test of beams and decking with 4” of concrete. The concrete was then loaded with an additional 1038 lbs using hydraulic jacks. The test went to 174 minutes restrained for the lighter beams and decking and 176 minutes for the heavier sections.

Beams & Columns at Omega Point, Revised at Intertek

Test Name: ASTM E119-00a
Location: Omega, revised at Intertek
Test Date: 07.08.2005, revision date 8.17.2017

This was a test of various structural steel column sizes with different coating thicknesses. The lightest of the series was a W8x31 with only 50 mils of Contego, which lasted just over 1 hour. The heaviest specimen, a W12x106 with 74 mils never failed.

Beams & Columns at Intertek

Test Name: ASTM E119-00a
Location: Intertek
Test Date: 07.08.2005

In this test, we examined the fire resistance of eight different columns with various thicknesses of the Contego coating to determine a range of possible application methods. Steel size ranged from a W8x31 to a W12x106. Coating thickness ranged from 50 mils (dft) to 76 mils (dft). The results ranged from 1 hour for the lightest steel with the thinnest coat to greater than the 2 hour limit with the heaviest steel and the second thickest coating.

W10x49 Over application at Omega

Test Name: ASTM E119-00a
Location: OPL
Test Date: 07.21.2003

This test was designed to demonstrate the negative effects of over applying Contego’s Fire Barrier Latex. With 95 mils (dft) the full scale W10x49 went to 87:48, less than similar tests with a proper thickness – proof that you can have too much of a good thing.

.250 Plate at V-Tech

Test Name: ASTM E119-00a
Location: VTEC
Test Date: 04.07.2003

We tested .250 plate steel after welding a flange to the midpoint to compromise the durability. (Flanges are the weak link for almost all intumescents). 73 mils (dft) of coating were applied and the test went to 2:06:00 when the average of the thermocouples exceeded the maximum allowable temperature. The char layer was 6″ thick and completely blanketed the flange.

Here we evaluated the effect of a top coat of acrylic enamel using a highly flammable Rust-O-Leum alkyd based paint. The test proved that top coating actually enhances Contego’s fire resistance by 25% to 32% consistently. Similar testing with other substrates provides similar or identical outcomes.

Location: Underwriters Laboratories
Test Date: 01.03.2007

This is a standard flame spread and smoke production test. Contego was applied thinner than normally recommended, 2 coats at a spread rate of 145 sq. ft. per gallon, versus our specified 2 coats at 130 sq. ft. per gallon. Regardless, the tests results show an averaged outcome of 0 flame spread and 0 smoke production. Contego gets better flame spread and smoke production results on Douglas Fir plywood than other intumescents get on steel.

ASTM E-119 – 08 “Standard Methods of Fire Tests of Building Construction & Materials” 

While concrete is obviously noncombustible, it still builds up thermal energy quickly and then explodes. When the cold side ruptures, the wall collapses.

In this test, which was performed at Guardian Laboratories in New York, we demonstrate that you can protect a concrete block wall for more than 3 hours with a super thin coat of Contego. Even with a top coat, Contego provides protection that you can trust.

ULc-S101/UL-263  “Full Scale on Structural Steel – 3 hours”

Location: Intertek Laboratories, Coquitlam, BC CANADA
Test Date: 01.20.2012

This was a full scale test using two sizes of beams and decking with 4” of concrete. The concrete was placed in segmented panels with a 1” gap to avoid the supportive effect that would happen with one contiguous pour. It was then loaded with an additional 1038 lbs/lf using hydraulic jacks. The test went to 174 minutes restrained for the lighter beams and decking and 176 minutes for the heavier section.
