CAN/ULC-S701-05

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.
