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 labeling. 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. 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. 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.
