ANSI/UL 263 (ASTM E119, ISO834) – Fire Tests of Building Construction and Materials
This cellulosic fire test is traditionally used to evaluate materials for use in the protection of modern day commercial structures. This test reaches 1000°F (537°C) after 5 minutes and gradually reaches a temperature of 2000°F (1093°C) after a period of 4 hours.
CAFCO FENDOLITE M-II is classified by Underwriters Laboratories for up to 4 hours protection in accordance with the cellulosic fire test and is listed within various UL Designs.
ANSI/UL 1709, Rapid Rise Fire Test of Protection Materials for Structural Steel
This fire test is provided to evaluate 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 E 119, 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 and CAFCO FENDOLITE TG are 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 XR704 , UL Design XR729 , UL Design XR730
BS 476, Parts 20-21: 1987 Appendix D – Hydrocarbon Heating Conditions
BS 476 Part 21:1987 is the British Standard method for determination of the fire resistance of load bearing elements of construction including Beams, Columns, Floors, and Flat roofs. CAFCO FENDOLITE M-II has undergone testing and meets the criteria for five limiting temperatures ranging from 662°F (350°C) to 1022°F (550°C). Thicknesses of CAFCO FENDOLITE M-II have been determined based on the required hourly rating and steel sections’ W/D (Hp/A) ratios.
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 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 has been issued a Lloyd’s Register Certificate after successfully completing this test.
ANSI/UL 1709 Rapid Rise Fire Test (following a Gas Explosion Test)
The above test serves to demonstrate the fire protection material’s ability to withstand a blast or explosion as well as the resulting pool fires. An ANSI/UL 1709 Rapid Rise Fire Test was conducted after the CAFCO FENDOLITE M-ll protected steel members were subjected to a gas explosion test (maximum overpressure of 3.11 bars).
CAFCO FENDOLITE M-ll has been successfully tested and meets the criteria of this combined test and carries a Lloyd’s Register Certificate.
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 that 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 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)
This test subjects fire resistive material to high velocity fire and a gas explosion replicating what often occurs 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 meets the criteria of this combined test and carries a Lloyd’s Register Certificate.
NFPA 58, Annex H- Procedure for Torch Fire and Hose Stream Testing of Thermal Insulating Systems for 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 International 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 has been successfully evaluated to this procedure and carries a Lloyd’s Inspection Certificate.
ANSI/UL 1709 Type 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 test sample was submerged in a liquid nitrogen bath and subsequently subjected to a UL 1709 type fire test. The results determined the CAFCO FENDOLITE M-ll material was resistant to freezing temperatures, prevented the steelwork from reaching embrittlement temperature, and will survive the thermal shock of a fire immediately afterwards.
Fire Protective Coating for LP-Gas Steel Storage Vessels and Process Structures (Class 4971)
Isolatek International has conducted three major tests on its CAFCO FENDOLITE M-ll fire resistive material according to the LP- Gas Steel Storage Vessel and Process Structures Class #4971 industry standard; fire testing, hose stream testing, and heat of combustion testing.
CAFCO FENDOLITE M-ll meets this standard and is approved by FM Global (Report No. 3040498) and is listed within the FM Approval guide.
GEIE GASAFE Program (LPG Storage Vessels)
Following a series of LPG tank explosions in Europe in the 1970’s, authorities took action to prevent these accidents and develop new protection standards. As a result, the GASAFE test program was formed. This program used scaled-down vessel models, which were evaluated in accordance with a hydrocarbon time-temperature curve with hose stream. It is generally known that the GASAFE application method is the preferred method since it was evaluated in accordance with a more realistic testing protocol for protection of LPG storage vessels.
CAFCO FENDOLITE M-II has been successfully tested in accordance with the GASAFE test program by CTICM and CSTB fire testing laboratories in Europe.
Rijkswaterstaat (RWS) Curve
Following a chain of major tunnel fires across Europe, the Ministry of Transport in the Netherlands developed the Rijkswaterstaat (RWS) curve, which is now the global standard for testing materials for use in tunnel fire protection. Materials that pass this test provide a means of effective fire protection for the concrete lining within tunnels to prevent concrete spalling under impact and thermal shock. The material is designed to inhibit the surface of the concrete lining from exceeding a temperature of 716°F (380°C) when subjected to fire exposure after a duration of two hours. This fire test represents the ignited contents of a 45,000 litre gasoline tanker spread over a surface area of 150 m².
Based on a series of full scale comprehensive fire tests, studies and analysis, the CAFCO FENDOLITE M-II system meets and exceeds the requirements and carries numerous Efectis Group Certificates.
Increased Time/Temperature Curve (HCinc)
This curve was developed to meet the French Ministry of Transport Regulations (CIRCULAIRE INTERMINISTERIELLE No. 2000-63 introduced in August 2000) and represents the temperatures generated in tunnel fires. The maximum temperature of the HCinc curve is 2372°F (1300°C) which is more severe than the standard BS 476 Part 21, UL 1709, and other hydrocarbon Time/Temperature curves.
