REDUCED SCALE FIRE TEST - HEPTANE FILLED INTERMEDIATE BULK
CONTAINERS (IBCs)
Issued: July 24, 2019

Executive Summary
The test described in this report was conducted for the Mauser Packaging Solutions at UL’s
Large Fire Test Facility located in Northbrook, IL. The fire exposure testing described herein
was conducted on composite IBC’s manufactured by Mauser that were constructed to be in
compliance with ANSI/UL 2368, Standard for Fire Exposure Testing of Rigid Nonmetallic and
Composite Nonmetallic Intermediate Bulk Containers for Combustible Liquids dated October
10, 2018.
One fire performance test was conducted in general accordance with ANSI/UL 2368, except
that the IBCs were filled with heptane (a flammable liquid having a nominal flash point of 25°F)
rather than mineral seal oil within 48 hours of the fire test. This test was conducted to generate
fire test data on a liquid having a higher vapor pressure and lower flash point compared to
mineral seal oil when stored within an IBC constructed to comply with ANSI/UL 2368.
During and after this test, there was no leakage from the IBCs. The IBCs maintained their
structural integrity such that the measured stack lean was approximately 2 degrees from the
vertical plane.
This test data shall not be used to substantiate the acceptability of these IBCs for use with
flammable liquids.

1. GENERAL
Mauser Packaging Solutions supplied all of the test samples for testing by UL.
The issuance of this report in no way implies that a UL Classified IBC is suitable for use
with flammable liquids.
Due to the nature of this investigation, it is understood that you will not use the name of
UL LLC, any abbreviation thereof, or symbol therefore, nor permit such use by others, in
connection with the release, publication, or other dissemination of the information obtained
under this application, unless specifically authorized in writing by UL LLC.
The sole purpose of this investigation is to subject two UL Classified, heptane filled IBCs
to a reduced-scale fire test and report the results. No conclusions have been made from the
data obtained. The information obtained by this investigation is being submitted to Mauser
Packaging Solutions for their use.
2. SAMPLES
Two samples were tested in accordance with the method stated below.
The samples were submitted by Mauser Packaging Solutions.
Representative photographs of the samples can be seen in Figures 1 and 2.
UL LLC did not select the samples nor witness the production of the test samples, however
Mauser Packaging Solutions has indicated that they were produced in accordance with the
UL follow-up service procedure for their UL Classified SM 13 EX UL design.
The test results apply only to the actual samples tested by UL.

3. TEST METHOD
Reduced-Scale Fire Performance Test
The reduced-scale fire performance test was conducted in an enclosed test cell having a
smooth, flat 30-ft (9.2-m) high ceiling. A sprinkler system utilizing four open K=11
nominal 5/8-in (1.6-cm) orifice upright style sprinklers were installed on a nominal 8-by-
10 ft. (2.4-by-2.5 m) spacing and installed with the sprinkler deflectors 3 inches (76.2 mm)
below the ceiling. The piping system was supplied with water under adequate pressure and
flow to maintain a 0.60-gpm/ft2 discharge density.
A 50-ft2 (4.6-m2) square steel test tray at least 10 inches high was centered below the four
sprinklers and fitted with a solid flat steel platform to provide a 2 ft. open area along 2
adjacent sides of the tray. See Figures 3 and 4.
Water was added to the tray so as to maintain a liquid level within 1 - 2 inches (2.5 - 5.0
cm) below the platform which was resting directly on top of the tray. The test tray was then
fitted with a fuel supply pipe with the discharge end positioned at least 1 inch (2.5 cm)
below the water surface.

Figure 4 – Reduced Scale Fire Test Arrangement – Plan View – Detail
Two IBCs identified in the sample section were filled to capacity with heptane. The IBC
was labeled with a 275 gallon capacity. The IBCs were then stacked one on top of the
other and positioned on the edge of the test platform as shown in Figure 4 and Figure 5.
One of the exposed sides of each IBC contained the outlet valve housing (doghouse).
Heptane was allowed to flow into the test tray at 2-gpm for 3 minutes. The heptane was
then ignited and the 2 gpm heptane flow maintained for the duration of the test. One minute
after ignition, water was discharged from the open sprinklers to provide a design density
of 0.60 gpm/ft2. The tray was fitted with a drain located near the bottom and arranged in
such a manner that the liquid level in the tray was maintained within 1 - 2 inches of the
bottom of the platform for the entire duration of the test.
The test was conducted for a total of 20 minutes, or until there was evidence of leakage or
loss of structural integrity of either IBC. If no leakage or loss of structural integrity was
observed, the heptane fuel flow was to be shut off and the pool fire extinguished within 1
minute after test termination. Each IBC was then to be examined for any signs of leakage.
A photograph of the test arrangement can be seen in Figure 5.
Photographs during the fire test can be seen in Figures 6 and 7.

4. RESULTS
The test was conducted for 20 minutes after ignition with no noticeable leakage in either
the bottom or top IBCs. The residual fires were extinguished within a minute after
termination of the test.

5. SUMMARY
The fire exposure testing described herein was conducted on composite IBC’s
manufactured by Mauser that were constructed to be in compliance with ANSI/UL 2368,
Standard for Fire Exposure Testing of Rigid Nonmetallic and Composite Nonmetallic
Intermediate Bulk Containers for Combustible Liquids dated October 10, 2018.
One fire performance test was conducted in general accordance with ANSI/UL 2368,
except that the IBCs were filled with heptane (a flammable liquid having a nominal flash
point of 25°F) rather than mineral seal oil within 48 hours of the fire test. This test was
conducted to generate fire test data on liquid having a higher vapor pressure and lower
flash point compared to mineral seal oil when stored within an IBC constructed to comply
with ANSI/UL 2368.
The following are the acceptance criteria for ANSI/UL 2368, Reduced Scale Fire Test:
Leakage:
Requirement: There is to be no leakage as defined by loss of liquid from the IBC
at a location below its full liquid level. The units are to be examined 24 hours after
completion of the test for any sign of leakage.
Result: There was no leakage from either unit that resulted in a loss of heptane.
Structural Integrity:
Requirement: The IBC shall remain in an upright position without toppling over
or leaning more than 5 degrees from a vertical plane.
Result: The units did not topple over during the test. The post test measurement
on the upper IBC which had the highest amount of leaning was 2 degrees from
vertical.
This test data shall not be used to substantiate the acceptability of these IBCs for use with
flammable liquids.
