(Specification)Standard Specification for Rigid Cellular Polystyrene Geofoam
Standard Specification for Rigid Cellular Polystyrene Geofoam
SCOPE
1.1 This specification covers the types, physical properties and dimensions of rigid cellular polystyrene intended for use as geofoam.
1.2 This specification does not cover the layout, placement and workmanship for proper installation and performance of rigid cellular polystyrene geofoam.
1.3 Rigid cellular polystyrene geofoam covered by this specification may need protection from certain chemicals, environmental exposure, and concentrated loads. Additional design considerations may include thermal conductivity and buoyancy. Guidelines regarding these end use considerations are included in Appendix X1.
1.4 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 requirements prior to use.
