(Specification)Standard Specification for Flat Wall Insulating Concrete Form (ICF) Systems
Standard Specification for Flat Wall Insulating Concrete Form (ICF) Systems
SCOPE
1.1 This specification is intended to apply to Insulating Concrete Form (ICF) Systems that will act as permanent formwork for cast-in-place reinforced concrete beams; lintels; exterior and interior, above and below grade bearing and non-bearing walls; foundations; and retaining walls. The specification is restricted to ICF Systems with a resultant uniform monolithic concrete core.
1.2 Products covered by the specification consists of molded expanded polystyrene (EPS) insulation panels that are connected by cross ties to form the ICF System.
1.3 This specification identifies test methods appropriate for establishing ICF System performance in their primary function as a stay in place concrete forming system. The use of ICF Systems covered by this specification shall be regulated by building codes that address fire performance, structural performance or both. The fire performance of the material shall be addressed through standard fire test methods established by the appropriate governing documents. The structural performance must be addressed through design of concrete structures in accordance with the appropriate Code requirements.
1.4 Details of manufacturing procedures are beyond the scope of this specification.
1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard. For conversion to metric units other than those contained in this specification, refer to IEEE/ASTM SI 10.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

F = average ultimate load in test series, N.
(2) Metal Cross Ties—The allowable lateral strength of the connection shall be determined in accordance with AISI NAS-01,
Chapter F.
6.2.4.3 Withdrawal Load Strength (Plastic or Metal Cross Ties)—Test specimens shall consist of full-thickness ICF panels, with
the fastener for which recognition is sought, screwed into the cross-tie flange in a manner representative of the end-use
configuration. Pilot holes for screws shall not be predrilled into the specimen.
(1) The ultimate load shall be determined for each test specimen.
(2) The allowable withdrawal load strength of the connection shall be determined based on the average ultimate load divided
by a safety factor of 5.
6.2.5 Cross Tie Tensile Strength—The integrated cross tie
