Description / Abstract:

This Standard applies to surge protective device (SPD) components designed to mitigate the effects of transient overvoltages and surge events and intended for use in surge protective devices (SPDs) or in non-SPD applications.

SPD Components containing integral thermal devices are within the scope of this Standard.

Components include but are not limited to metal oxide varistors (MOVs), silicon avalanche diodes (SADs), spark gaps (open or sealed type), and gas discharge tubes (GDT). 

This Standard does not apply to products that are combinations of components nor to assemblies that use these components as covered in CSA C22.2 No. 269.4. 

Components such as inductors or capacitors and other essentially linear components are not considered SPDs. 1.6 The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only. 

In this Standard, “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.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (nonmandatory) to define their application
