Scope:

1.1 General

This Standard specifies requirements related to hot water delivery, minimum standby performance, heater element ratings, and marking of electric storage tank water heaters.

1.2 Tank capacity

This Standard applies to stationary storage tank water heaters that have a rated capacity of 50 to 454 L (11 to 100 gal) and are intended for use with pressure systems in residential premises and similar locations. For convenience, the term water heater is used in this Standard to refer to such heaters.

1.3 Mandatory language

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. Legends to equations and figures are considered requirements.

1.4 Units of measurement

The values given in SI (metric) units are the standard. The values given in parentheses are for information only. All measurements in gallons refer to imperial gallons.

Project need:

To review the Standard within the required 5 year period.
