1. SCOPE 1.1 This Standard specifies the requirements for factory made rigid expanded
polystyrene insulation in the form of pipe covering and boards with or without facings or coatings
made by moulding (EPS) or extrusion (XPS) of expandable polystyrene beads. This Standard
does not apply to laminated products manufactured with any type of rigid board facer including
fibreboard, perlite board, gypsum board, or oriented strand board. 1.2 The Standard describes product characteristics and includes procedures for
testing, evaluation of conformity, marking and labelling. 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. 1.3 Products covered by this Standard are also used for sound insulation and in
prefabricated thermal insulation systems and composite panels. The performance of systems
incorporating these products is not covered. NOTES: 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. 1.4 This Standard does not purport to address all possible end-use concerns. It is the
responsibility of the user of this Standard to contact the manufacturer regarding design
considerations including specific end-use applications. 1.5 This Standard does not purport to address all the health and safety aspects
associated with its use. Anyone using this Standard has the responsibility to consult the
appropriate authorities and to establish health and safety practices, in conjunction with any
existing applicable regulatory requirements prior to its use.
