PrefaceThis is the second edition of CSA B483.1, Drinking water treatment systems. It supersedes the previous edition published in 2007. The major changes in this new edition are the addition of a) requirements for point-of-entry systems, devices, or both in Clauses 4.1.1 and 6.4; b) lead content requirements in Clause 4.1.2; and c) inline valve requirements in Clause 4.8. This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.Scope1.1 General This Standard covers drinking water treatment systems that are a) point-of-use or point-of-entry plumbed-in systems; and b) point-of-use non-plumbed-in 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 Electrical requirements 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 Terminology 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 (non-mandatory) to define their application.1.4 Units of measurement 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.
