Cellulosic – ANSI/UL263 (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 and CAFCO FENDOLITE TG are classified by Underwriters Laboratories for up to 4 hours protection in accordance with the cellulosic fire test and is listed within various UL Designs.
Hydrocarbon – UL1709, Underwriters Laboratories – Rapid Rise Fire Tests 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/UL1709 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 >
Hydrocarbon – BS 476, Parts 20-21: 1987 Appendix D – Hydrocarbon Heating Conditions
BS476 Part 21 1987 is the British Standards 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 section’s W/D (Hp/A) ratios.
Hydrocarbon – 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 BS476 Part 21, UL 1709 and other hydrocarbon Time/Temperature curves.
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 150m².
Based on a series of full scale comprehensive fire tests, studies and analysis, the CAFCO FENDOLITE M-II system meets and exceeds the requirements.
Three Bar Overpressure Blast Explosion Testing with Subsequent Hydrocarbon Fire Testing
To determine the ability of fire protection materials to withstand a blast or explosion, a series of blast overpressure tests, followed by a hydrocarbon fire test is essential in order to determine the durability of the material. These tests are carried out by means of applying the fire resistive material to steel members and subjecting them to blast overpressure testing directly followed by a hydrocarbon fire test.
Isolatek International subjected CAFCO FENDOLITE M-II to this test at Advantica Spadeadam Test Facility in the UK. The tests were independently witnessed by Lloyd’s Register of Shipping. Three separate tests were conducted, peaking at 3.11 atmospheres (6580 psf). The specimens survived without any damage. After the tests were complete, the members successfully were subjected to hydrocarbon fire testing in accordance with UL1709.
Three Bar Overpressure Blast Explosion Testing with Subsequent Jet Fire Testing
Of utmost importance is substantiating the integrity of a fire resistive material or system to withstand a blast or explosion prior to subsequent exposure to the erosive forces of a high velocity jet fire. Subjecting the material to Three Bar Overpressure Blast Explosion Testing with Subsequent Jet Fire Testing replicates 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. This test recognizes the destructive erosive nature from potential gas releases and associated intense heat flux resulting from the ignition of a gas release.
CAFCO FENDOLITE M-II has been tested for three bar overpressure blast resistance and jet fire resistance according to ISO 22899-1 (J30).
Lloyd’s Register – Jet Fire Test
Fire protection material resistance to Jet Fire is an essential test for evaluating the protection of steel structures within petrochemical and similar industrial industries. This type of testing has evolved from the recognition of more destructive fire scenarios than those involved in standard hydrocarbon fueled pool fires. This test simulates the more intense heat and mechanical forces due to a pressurized fuel source.
CAFCO FENDOLITE M-II has undergone a large scale Jet Fire test and exceeds the requirements resulting in Lloyds Register Type Approval Certificate – SAS F110166.
LPG Storage Tanks
Factory Mutual (FM) – LPG Storage Vessels and Process Structures:
In order to meet the Factory Mutual requirements Liquefied Petroleum (LP) gas steel storage vessels and process structures, CAFCO FENDOLITE M-II has been tested and is approved by Factory Mutual Research Corporation resulting in Approval Report No. 3040498 along with the listing within the FM Approval guide (Class Number 4971).
GASAFE – 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.
Liquid Nitrogen Immersion
It is important that fire protection materials must still perform in the event of cryogenic exposure. A UL1709 type fire test was carried out on CAFCO FENDOLITE M-II to obtain an indication as to the performance when applied to a steel member that had been exposed to a ten minute cold splash of liquid nitrogen immediately prior to fire testing. The sample was evaluated compared to a control sample. Based on results of the testing, it was determined that the CAFCO FENDOLITE M-II material that had been subjected to the cold splash of liquid nitrogen reacted equally when evaluated against UL1709 time-temperature curve conditions as compared to the control sample.
