1. SCOPe 1.1 This standard contains requirements and test methods for rigid expanded
polystyrene insulation in the form of pipe covering and boards made by moulding
(EPS) or extrusion (XPS) of expandable polystyrene beads. The standard covers
four types of rigid expanded polystyrene distinguished on the basis of their
material properties. Products manufactured to this Standard are intended for
use as thermal insulation in building construction and other applications for
temperatures ranging from -54°C to + 75°C. NOTE: 1. For more detailed information on product properties, see
Subsection 8.2. 2. For applications other than the above - e.g., cryogenic,
flotation, etc. - consult manufacturers for specific
recommendations and properties.
