Standard Specification for Rigid Cellular Polystyrene Geofoam
ABSTRACT
This specification presents the types, physical properties, and dimensions of rigid cellular polystyrene (RCPS) intended for use as geofoam. This specification, however, does not address the layout, placement, and workmanship for proper installation and performance of the geofoams. RCPS geofoams shall be formed by the expansion of polystyrene resin beads or granules in a molding process (EPS), or by the expansion of polystyrene base resin in an extrusion process (XPS). They may also be manufactured with reprocessed polystyrene foam (regrind). The RCPS geofoams shall meet combustibility and curing requirements and, when tested, shall adhere to physical property requirements such as dimensions and density, compressive resistance, flexural strength, and oxygen index. Final products should also meet surface damage, volume damage, and UV degradation limits.
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.
