UL-1709, BS476: Part 21 - UL-1709

ANSI/UL 1709 Rapid Rise Fire Test of Protection Materials for Structural Steel

This fire test evaluates materials for use in petrochemical facilities and other similar structures that may be subjected to higher levels of heat generated by hydrocarbon-based fires. Unlike cellulosic-based fires, which are evaluated in accordance with test method ANSI/UL 263, ASTM E119, which reaches a temperature of 2000°F (1093°C) over a period of 4 hours, the ANSI/UL 1709 test method reaches 2000°F after five minutes and maintains that temperature over the duration of the test. Only materials tested and classified in accordance with UL 1709 can be used where the risk of a hydrocarbon fire exists.

CAFCO FENDOLITE M-II/P is classified by Underwriters Laboratories for up to 4 hours protection in accordance with the Rapid Rise Fire Test. The specific listing within the UL Fire Resistance Directory is UL Design XR725 >

2nd ANSI/UL 1709, Rapid Rise Fire Test of Protection Materials for Structural Steel (following initial ANSI/UL 1709 Rapid Rise Fire Test)

2nd ANSI/UL 1709, Rapid Rise Fire Test of Protection Materials for Structural Steel (following initial ANSI/UL 1709 Rapid Rise Fire Test) as above however subjecting CAFCO FENDOLITE M-II/P to Two Full Scale UL 1709 Fire Tests within a 24-hour period (tested, allowed to cool to ambient and re-tested).

ANSI/UL1709 Environmental Exposure Tests (Aging, High Humidity, Industrial Atmosphere, Salt Spray, Combined Wet/Freeze/Dry Cycling, Acid Spray and Solvent Spray)

In addition to the required ANSI/UL1709 environmental exposure tests (Aging, High Humidity, Industrial Atmosphere, Salt Spray and Combined Wet/Freeze/Dry Cycling), CAFCO FENDOLITE M-II/P has also been tested under the following conditions:

  • Acid Spray – Exposure of the material (with and without topcoat) to a hydrochloric acid /water fog spray.
  • Solvent Spray – Exposure of the material (with and without topcoat) to a spray applied solvent for 5 cycles. Each cycle consists of the application of the solvent, 6 hour dry time, re-application of the solvent, and dry time of 18 hours.

Gas Explosion Test (3-Bar Blast Overpressure)

Gas Explosion Test (3-Bar Blast Overpressure)

The above test serves to demonstrate the resistance and thermal performance of a fire resistive material subjected to a blast, either by fueled or explosive sources. Steel members protected with CAFCO FENDOLITE M-ll/P were subjected to a blast (having a nominal overpressure of 3 bars) in accordance with Spadeadam Site Test Procedure No. 108. The results following this extensive blast revealed little to no damage to the fire resistive material.

CAFCO FENDOLITE M-ll/P has been issued a Lloyd’s Register Certificate after successfully completing this test.

ISO 22899-1 Determination of the Resistance to Jet Fire

ISO 22899-1 Determination of the Resistance to Jet Fires of Passive Fire Protection Materials

Testing a material’s fire resistance under jet fire has arisen from the industry’s recognition there are fire scenarios more destructive than standard hydrocarbon pooled fires. The jet fire described in ISO 22899-1:2007 involves the sonic release of propane vapor which produces an intense fire ball. The test sample is exposed to a combined radiative and convective heat flux as well as significant erosive forces due to the velocity of the jet.

CAFCO FENDOLITE M-ll/P has been tested and meets the criteria for a J-120 rating in accordance with the ISO 22899-1 Jet Fire Test and is covered in a Lloyd’s Register Certificate.

ISO 22899-1 Jet Fire Test following Gas Explosion Test

ISO 22899-1 Jet Fire Test (following Gas Explosion Test)

This test subjects fire resistive material to high velocity fire and gas explosion replicating what often occurs in practice when a vapor cloud explosion results in a jet fire that produces intense heat and erosive forces from a pressurized fuel source.

CAFCO FENDOLITE M-ll/P meets the criteria of this combined test and carries a Lloyd’s Register Certificate.

NFPA 290 / 58 Annex H Torch Fire and Hose Stream

NFPA 290, NFPA 58, Annex H Standard for Fire Testing of Passive Protection Materials for use on LP- Gas Containers

Subjecting materials to a combination of torch and hose stream testing provides a simulated condition that mimics a fire event to a LP gas storage Vessel- including the potential impingement effects to the vessel when fighting the fire. Isolatek opted for extended torching time in this test to show that the material provides results which exceed the actual industry approval requirements.

CAFCO FENDOLITE M-ll/P has been successfully evaluated to this procedure.

Steel and Concrete Fire Protection Tank Farms - GASAFE - LPG Storage Vessels

Fire Protective Coating for LP- Gas Steel Storage Vessels and Process Structures (Class 4971)

Isolatek International has conducted three major tests on its fire resistive material according to the LP- Gas Steel Storage Vessel and Process Structures industry standard; fire testing, hose stream testing, and heat of combustion testing.

CAFCO FENDOLITE M-ll/P meets this standard and is approved by FM Global (Report No. 3040498) and is listed within the FM Approval guide.

ANSI/UL 1709 Rapid Rise Fire Test (following Liquid Nitrogen Immersion Test)

Exposing a fireproofed steel member to a ten minute cold splash of liquid nitrogen models the cryogenic conditions that can occur in a LNG loading facility. The CAFCO FENDOLITE M-ll/P test sample was submerged in a liquid nitrogen bath and then subjected to a UL 1709 type fire test. The results determined the CAFCO FENDOLITE M-ll/P material was resistant to freezing temperatures, prevented the steelwork from reaching embrittlement temperature, and will survive thermal shock of a fire immediately afterwards.

CAFCO FENDOLITE M-II/P carries a Lloyd’s Register Certificate covering this test.

“CAFCO® FENDOLITE® M-II/P is the most proven and time tested material used within petrochemical and industrial environments in the world.”

Fire protection materials installed within petrochemical and other industrial environments require
resilience to endure extreme conditions for prolonged periods of time. In order to survive these conditions,
fire resistive materials must be able to withstand exposure to solvents, oils, chemicals, mechanical abuse and
direct exposure to weathering conditions.

Through our sophisticated research and development team, Isolatek International develops all of our products
to meet and exceed industry specification guidelines.

Isolatek International utilizes the services of well-known independent third party testing laboratories to evaluate
all of our materials to ensure that owners and designers are receiving the exceptional durability that we publicize.
