Preface:This is the second edition of ASME A112.19.7/CSA B45.10,Hydromassage bathtub systems.It supersedes the previous edition published in 2012.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.This Standard was approved as an American National standard by the American National Standards Institute on March 5, 2020.Scope:1.1This Standard specifies general requirements, test methods, and markings for whirlpool and air-jetted bathtubs and suction fittings used in hydromassage bathtub systems that incorporate a bathtub and circulation pump. The circulation pump can be with or withouta) a piping system; andb) induction of air (which can be achieved by integral suction or through an air pump).1.2This Standard does not covera) spas and hot tubs covered in CAN/CSA-C22.2 No. 218.1 and UL 1563;b) portable hydromassage products covered in CSA Electrical Bulletin 1268 and CSA Electrical Bulletin 1270; andc) hydrotherapy bathtubs or patient bathing systems for institutional use.1.3In 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.1.4SI units are the units of record in Canada. In this Standard, the inch/pound units are shown in parentheses. The values stated in each measurement system are equivalent in application; however, each system is to be used independently. Combining values from the two measurement systems can result in non- conformance with this Standard. All references to gallons are to U.S. gallons. For information on the conversion criteria used in this Standard, see Annex A.
