CSA Group Drinking Water Treatment Systems

Preface This is the first edition of CSA B483.1, Drinking water treatment systems.  This Standard was developed in response to a request to specify plumbing, mechanical, requirements for drinking water treatment components and complete systems.  Scope 1.1 This Standard covers drinking water treatment systems that are: (a) point-of-use or point-of-entry plumbed systems and (b) point-of-use non-plumbed systems. Note: Drinking water treatment systems covered by this Standard are intended to be used for the reduction or inactivation of harmful substances that can be present in drinking water.  1.2 This Standard includes electrical requirements for drinking water treatment systems that are intended (a) to be permanently connected, cord and plug connected, or connected through a Class 2 plug-in power supply to an electrical supply circuit of 250 V or less (i.e., 150 V maximum to ground); and (b) for use indoors in non-hazardous locations in accordance with the Canadian Electrical Code, Part I.  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; "may" is used to express an option or that which is permissible within the limits of the standard; and "can" is used to express possibility or capability.  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 (non-mandatory) to define their application.  1.4 The values stated in SI (metric) are the standard. The values given in parentheses are for information only.
