lamps that are designed for an operating capability that partially falls within 100 and 130 V.

This Standard does not include requirements for luminaires used with general service lamps.

1.3
In 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.

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.
