Consensus implies much more than a simple majority, but not necessarily unanimity”. It is consistent with this definition that a member may be
34、 included in the Technical Committee list and yet not be in full agreement with all clauses of this publication.(4) CSA Standards are subject to periodic review, and suggestions for their improvement will be referred to the appropriate committee.(5) All enquiries regarding this Standard, including r
35、equests for interpretation, should be addressed to Canadian Standards Association, 5060 Spectrum Way, Suite 100, Mississauga, Ontario, Canada L4W 5N6. Requests for interpretation should(a) define the problem, making reference to the specific clause, and, where appropriate, include an illustrative sk
36、etch;(b) provide an explanation of circumstances surrounding the actual field condition; and(c) be phrased where possible to permit a specific “yes” or “no” answer.Committee interpretations are processed in accordance with the CSA Directives and guidelines governingstandardization and are published

39、umbing fixtures with pumped waste and macerating toilet systems1 Scope1.1This Standard establishes physical, performance, and testing requirements applicable to plumbing fixtures with pumped waste, macerating toilet systems, and related components. Such systems are intended to collect waste from a s
40、ingle fixture such as a water closet, lavatory, shower, or bathtub and pump these wastes to some point in the sanitary drainage system.1.2The purpose of this Standard is to establish a generally acceptable performance standard for pumped waste systems, macerating systems and related components for d
41、irectly affixed water closets and other fixtures designed for above the-floor or in-floor installations.1.3A water closet connects to a macerating toilet system. Macerating toilet systems collect the waste from a single water closet, plus a lavatory, shower, bathtub, or a combination of these in the
42、 same room. Macerating systems grind and pump these macerated wastes to some point in the sanitary drainage system.1.4Pumped waste systems consist of three major components:(a) an automatic activation of the pumped waste system;(b) a drainage connection to the pump; and(c) a pump that pumps the wast
43、e to the gravity drainage system.1.5The macerating system comprises three major components:(a) a container that houses the operating mechanisms;(b) a pressure chamber that automatically or manually activates and deactivates the induction motor; and(c) an induction motor that drives the shredder blad
44、es and pump assembly, which is permitted to be combined into a single unit.1.6The use of alternate materials or methods is permitted, provided it can be demonstrated that such alternatives comply with the performance requirements of this Standard.1.7In this Standard, “shall” is used to express a req
45、uirement, 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” i
46、s used to express possibility or capability.

47、e 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.1.8 Units of measurementSI units are the unit
48、s 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 th
