PREFACE
Evaluation reports issued by ICC Evaluation Service, LLC (ICC-ES), are based upon performance features of
the International family of codes. (Some reports may also reference older code families such as the BOCA
National Codes, the Standard Codes, andthe Uniform Codes.) Section 104.11 of the International Building Code®
reads as follows:
The provisions of this code are not intended to prevent the installation of any materials or to
prohibit any design or method of construction not specifically prescribed by this code,
provided that any such alternative has been approved. An alternative material, design or
method of construction shall be approved where the building official finds that the proposed
design is satisfactory and complies with the intent of the provisions of this code, and that the
material, method or work offered is, for the purpose intended, at least the equivalent of that
prescribed in this code, in quality, strength, effectiveness, fire resistance, durability and safety.
This acceptance criteria has been issued to provide interested parties with guidelines for demonstrating
compliance with performance features of the codes referenced in the criteria. The criteria was developed through
a transparent process involving public hearings of the ICC-ES Evaluation Committee, and/or on-line postings
where public comment was solicited.
I
New acceptance criteria will only have 'an "approved" date, which is the date the document was approved by
the Evaluation Committee. When existing acceptance criteria are revised, the Evaluation Committee will decide
whether the revised document should carry only an "approved" date, or an "approved" date combined with a
"compliance" date. The compliance date is the date by which relevant evaluation reports must comply with the
requirements of the criteria. See the IMES web site for more information on compliance dates.
If this criteria is a revised edition, a solid vertical line (1) in the margin within the criteria indicates a change
from the previous edition. A deletion indicator (-*) is provided in the margin where any significant wording has
been deleted.
ICC-ES may consider alternate criteria for report approval, provided the report applicant submits data
demonstrating that the alternate criteria 'are at least equivalent to the criteria set forth in this document, and
otherwise demonstrate compliance with the performance features of the codes. IMES retains the right to refuse
to issue or renew any evaluation report, ifithe applicable product, material, or method of construction is such that
either unusual care with its installation or use must be exercised for satisfactory performance, or if
malfunctioning is apt to cause injury or unreasonable damage.
NOTE: The Preface for ICC-ES acceptance criteria was revised in July 2011 to reflect changes in policy.
Acceptance criteria are developed for use solely by ICC-ES for purpose of issuing IMES evaluation reports.

Test Method for Crawl Space Evaluation
(Refer to Appendix D, Section D2 iI 2.2 for additional specifications, pass/fail criteria and limitations)
E1.0 SCOPE
The objective of this test is to evaluate the fire! performance of foam plastic insulation materials when tested in a simulated
crawl space module to determine if the insulation is acceptable for use in crawl space areas without a thermal barrier. The test
provides a comparison of fire performance characteristics between insulated wood sub -floor assemblies.
E2.0 TEST CONFIGURATION
A sub -floor assembly is mounted on top of a three -sided wall module. The simulated crawl space module consists of three
8-ft square (0.74 m2) [outside dimensions ± 2 inches (51 mm)] walls, each 48 ± 2 inches (1219 mm ± 51 mm) high, and built of
nominal 4-inch-wide (102 mm) by 8-inch-high (203 mm) by 16-inch-long (406 mm) concrete blocks with a full open space on
one side of the structure. Masonry walls or module walls constructed of wood or metal studs with two layers of 1/2 inch (12.7
mm) gypsum board are permitted provided the in dimensions are the same as for a concrete block module, i.e., 88 ± 2
inch -wide (2235 mm ± 51 mm) and 92 ± 2 inch -deep (2337 mm ± 51 mm). If wood or metal stud construction is used, the
studs shall be located inside the module, i.e., the, width of the module is equal to the distance between the interior faces of the
gypsum board attached to the side walls and the: depth is equal to the distance between the front opening and the interior face
of the gypsum board attached to the back wall.
The floor/ceiling above the crawl space is built,using nominal 2 by 8-inch by 8-ft (2.4 m) floor joists on 16-inch (406 mm)
centers, with 2 by 8-inch joist headers, all bearing on 2 by 4-inch sill plates and surfaced with 15/32-inch-thick (12 mm), 4-ply,
APA graded A-C plywood sub -flooring. The use of joists and headers with a larger depth, e.g., 2 by 10 inch, 2 by 12 inch, etc.
is permitted at the client's request.
Note 1: The use of CDX grade plywood is considered too variable in quality for comparison purposes required for this
evaluation. j
Note 2: All construction lumber (joists and studs, if used) shall be of the same species and grade for all tests conducted to
qualify a foam plastic insulation.
The joists are perpendicular to the camera's line -of -sight, so that they tend to dam the flame front and hold it inside the test
area. The floor of the test chamber is covered with approximately 1 inch (25.4 mm) of sand. To provide additional protection, it
is acceptable to cover the floor with 1/2 inch (12.7'mm) gypsum board before installing the 1 inch (25.4 mm) layer of sand.
E3.0 IGNITION SOURCE
The fire source is a 22-lb (9.9 kg) wood crib constructed of nominal 2 by 2-inch No. 1 select grade white pine (no knots), 15-
inch square (9677 mm2) in plan, spaced approximately 11/2-in.ch (38 mm) apart and fastened at right angles with a single nail
at each end. The crib shall be conditioned to an average moisture content of 7.5 ± 0.5%. The crib is placed in a rear corner of
the crawl space 1 inch (25.4 mm) from each wall surface and supported approximately 4 inch (102 mm) above the floor on
small sections of refractory brick. The crib sticks of the bottom layer shall be parallel to the side walls. Approximately 150 ml of
ethyl alcohol in a circular or square metal pan with a surface area of 36 to 40 in (23226 mm2 to 25806 mm2) placed under the
crib is used for ignition.
E4.0 TEST DURATION AND END POINT COMPARISON CRITERIA
The following two criteria shall be measured and reported:
1. Time to flames emerging from the front of the crawl space.
2. Time to bum -through of the floor/deck system. If this criteria is not reached prior to laboratory personnel ending the test,
the time at which the test was ended and reason for ending the test shall be reported.
E5.0 DOCUMENTATION
The test is recorded with photographs and video documentation positioned to view the entire front of the open side of the
module. A timing reference, mechanical or electronic, is included in all photographic and video records.
E6.0 REPORT
The report shall include:
1. Name and location of facility where test is conducted.
2. A description of the tested assembly with emphasis on the insulation type (including facings), thickness, density and
attachment details.

Testing for Use in Attics and Crawl Spaces with Alternatives to Code -prescribed Ignition Barrier
i
X1.0 Scope:
X1.1 General: The objective of this testing is to evaluate the fire performance of spray -applied foam plastic insulation
materials when tested in a room/ -corner test configuration to determine if the insulation and/or the insulation system is
acceptable for use in attics and crawl spaces without prescriptive ignition barriers per the IRC or IBC.
X1.2 Use in Attics: Spray -applied polyurethane foam plastic insulation installed in attics where entry is made only for
service of utilities shall be protected by an ignition barrier as set forth in IBC Section 2603.4.1.6, IRC Section R316.5.3, or
2006 IRC Section R314.5, except as noted in Section D2.0.
X1.3 Use in Crawl Spaces: Spray -applied pIolyurethane foam plastic insulation installed in a crawl space where entry is
made only for service of utilities shall be protected by an ignition barrier as set forth in IBC Section 2603.4.1.6, IRC Section
R316.5.4, 2006 IRC Section R314.5.4, except as noted in Section D2.0.
X2.0 The prescriptive ignition barrier shall not be required when satisfactory testing is conducted with exposed foam plastic
insulation or with a foam plastic insulation system covered by a coating in accordance with the following:
X2.1 Test Method: The test procedure to be used is NFPA 286, "Standard Methods of Fire Tests for Evaluating
Contribution of Wall and Ceiling Interior Finish to Room Fire Growth," with the modifications described below.
X2.1.1 Ignition Source: The standard gas burner shall be used. The burner shall be positioned such that it is in contact
with both sidewalis in the test comer of the fire test room as indicated in Figure D1.
X2.1.2 Specimen Mounting: The test specimens can be mounted in either of two configurations. Whichever
configuration is used, the interior room dimensions as required by the NFPA 286 test procedure shall be maintained. The two
configurations are:
a. The fire test room shall be completelyl lined with one layer of 5/a-inch-thick (15.9 mm), Type X gypsum wallboard.
The SPF shall be applied directly to the gypsum wallboard at the maximum thickness and density intended for use. The SPF
shall be applied to both the three test walls and the test ceiling. If a covering is used over the foam, it shall be applied to both
the walls and the ceiling at the same minimum thickness or coverage rate intended for use.
b. The three walls of the test room without the doorway will be constructed with wood studs sized to the same depth
as the test specimen, 93 inches (2362 mm) high,! 24 inches (610 mm) on center with a single top and bottom plate, as shown
in Figure D2. The exterior side of the walls will be covered with one layer of 5/8-inch-thick (15.9 mm), Type X gypsum
wallboard. The SPF will be sprayed to fill each stud cavity and be continuous from the bottom plate to the top plate and from
stud to stud. The ceiling of the test room will be constructed as shown in Figure D3. The ceiling will consist of wood joists sized
to the same depth as the test specimen at 24 inches (610 mm) on center. A total of five joists will be used and they will run
parallel with the 12-foot length (3.6 m) of the testiroom (front to back). The two outboard joists will rest on the top plates of the
walls. The exterior side of the ceiling will be covered with one layer of 5/8-inch-thick (15.9 mm), Type X gypsum wallboard. The
SPF will be sprayed to fill each joist cavity and will be continuous from the front to the back and from joist to joist. If a coating
(e.g., intumescent coating) is used over the foam; it shall be applied to both the walls and the ceiling at the same minimum
thickness or coverage rate intended for use.
C. If a coating is used over the foam, its thickness shall be measured using the dry -film thickness technique (DFT),
using one of the following methods:
Method 1 (Slit -sample method)
i. Take two slit samples within 24 inches (610 mm) of the comer where the burner will be placed. The slit samples
shall be approximately 0.5 inch deep, 2-3 inches long (51-76 mm), and 0.5 inch (13 mm) wide. One face of the slit sample
(where the measurements will be made) shall be cut perpendicular to the surface of the spray polyurethane foam.
ii. Using an optical comparator, measure the coating thickness at four random locations on the face of each slit
sample. Avoid the thinnest and the thickest spots ion the samples. This will provide eight coating thickness measurements.
The average of these eight measurements must be used to determine the average coating thickness.
iii. The holes from which slit samples were taken must be filled with a nonflammable caulk or sealant.
iv. Weight or volume of the coating applied to the entire module area in (lb/ft2 or Gallons/ft2) shall be recorded along
with the measured DFT.
Method 2 (Medallion/target method)
17
ACCEPTANCE CRITERIA FOR SPRAY -APPLIED FOAM PLASTIC INSULATION (AC377)
I. Install two metal medallions within 24 inches (610 mm) of the corner where the burner will be placed. The
medallions shall be 2 inches by 2 inches (51 mm by 51 mm) with a'/< inch (6.4 mm) hole in the center to allow a nail or screw
to fasten the medallion to the foam surface.
ii. Using an optical comparator or caliper, measure the coating thickness (dry mils film thickness) at four random
locations of each medallion sample. Avoid the thinnest and the thickest spots on the samples. This will provide eight coating
thickness measurements. The average of these eight measurements must be used to determine the average coating
thickness.
iii. The bare spots on the foam where the medallions were removed shall be coated with nonflammable caulk, coating
or sealant prior to conducting the test.
X2.1.3 Test Corner Configuration: Duri g the installation of the SPF, care shall be taken to provide as smooth a
surface as possible, especially in the wall areas that will be adjacent to and above the burner. The maximum allowable
deviations are described in Figure D3.
X2.1.4 Test Data: During the test, all of the following test parameters shall be determined:
a. Time at which the Heat Release Rate exceeds 1 MW.
b. Time at which the heat flux to the floor exceeds 20 kW/m2.
c. Time at which the average upper layer temperature exceeds 600°C.
d. Time at which flames exit the doorway.
X2.1.5 D2.1.5 Report: The following additional items shall be reported:
a. Type, description, average thickness and nominal density of the SPF wall and ceiling specimens.
b. If used as part of the insulation system, the type, description, and nominal thickness (in mils) or application rate (in
gallons per 100 square feet) of coating.
c. Time recorded for each test parameter from Section D2.1.4 above.
d. Average of the four time values indicated in Item D2.1.4.
X2.1.6 D2.1.6 Conditions of Acceptance: A test shall be determined to be successful when the average time for
attainment of the four measured test parameters (Item D2.1.5c, above) is 4 minutes 18 seconds or greater. This acceptance
criteria is based on comparison of results for the tested assembly versus results for a code -prescribed ignition barrier applied
over foam plastic insulation.
X2.2 Limitations:
X2.2.1 Attic or Crawl Space Installation: When testing is in accordance with Appendix D, the evaluation report shall
include the following limitations:
a. Entry to the attic or crawl space is only to service utilities, and no storage is permitted.
b. There are no interconnected attic or'crawl space areas.
c. Air in the attic or crawl space is not circulated to other parts of the building.
d. Attic ventilation is provided when required by IBC Section 1203.2 or IRC Section R806, except when air -
impermeable insulation is permitted in unvented attics in accordance with the 2012 IRC Section R806.5, 2009 IRC Section
R806.4. Under -floor (crawl space) ventilation is provided when required by IBC Section 1203.3 or IRC Section R408.1, as
applicable.
e. The foam plastic insulation is limited to the maximum thickness and density tested.
f. Combustion air is provided in accordance with 2012 and 2009 IMC Section 701, or 2006 IMC Sections 701 and
703.
g. The installed coverage rate or thickness of coatings, if part of the insulation system, shall be equal to or greater
than that which was tested.
X2.3 Attic Floors:
The maximum thickness of foam plastic applied on the walls for the test method outlined in Appendix D can be used to
establish the maximum thickness of foam plastic without a covering in attic floors. If a proprietary ignition barrier is used on
the tested walls, it will be required for the attic floor application, also.
