Scope

1.1This Standard applies to mineral-insulated cables with copper, nickel-/nickel-alloy-clad copper, steel-clad copper, or nickel conductors, enclosed in a copper or stainless steel sheath.

1.2The constructions covered by this Standard are intended for use in power, instrumentation, control, and fire alarm systems in accordance with the Canadian Electrical Code, Part I.

1.3The constructions covered by this Standard are recognized for use where normal conditions are such that no part of the cable is subjected to a temperature in excess of 250 degrees C. When provided with an overall thermoplastic or thermoset protective covering, the use is restricted to 90 degrees C.

1.4The constructions covered by this Standard are(a) Type MI mineral-insulated, copper-sheathed cable recognized for use on systems having a nominal voltage of 600 V or less;(b) Type SSMI mineral-insulated, stainless steel-sheathed cable recognized for use on systems having a nominal voltage of 600 V or less;(c) Type LWMI mineral-insulated, copper-sheathed cable recognized for use on systems having a nominal voltage of 600 V or less; and(d) Type SSLWMI mineral-insulated, stainless steel-sheathed cable recognized for use on systems having a nominal voltage of 600 V or less.

1.5Optional requirements are provided for(a) twisted pair configurations;(b) copper or stainless steel shields;(c) overall thermoplastic or thermoset protective coverings;(d) flame test classification; and(e) fire rating.

1.6In CSA Standards, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the standard.
