30、 Standard.With the onset of the Free Trade Agreement between the United States and Canada on January 2, 1988, significant attention was given to the harmonization of the United States and Canadian safety standards addressing gas-fired equipment for residential, commercial and industrial applications

31、. It was believed that the elimination of the differences between the standards would remove potential trade barriers and provide an atmosphere in which North American manufacturers could market more freely in the United States and Canada. The harmonization of these standards was also seen as a step

32、 toward harmonization with international standards.During its October 1-2, 2008 meeting, the Joint Technical Advisory Group on Standards for Gas-Fired Water Heaters recommended a draft proposed standard, Z21.98 CSA 4.10, be distributed for review and comment as a harmonized standard. The first draft

33、 of the harmonized standard for non-metallic dip tubes for use in water heaters was distributed for review and comment during November 2008.Following reconsideration and modification of the proposed harmonized draft standard for non-metallic dip tubes for use in water heaters, the Joint Technical Ad

34、visory Group on Standards for Gas-Fired Water Heaters at its May 28, 2009 meeting, recommended the proposed standard to the Z21/83 Technical Committee and the CSA Technical Committee on Gas Appliances and Related Equipment for approval.The proposed harmonized standard for non-metallic dip tubes for

35、use in water heaters was approved by the Z21/83 Committee at their meeting on September 28, 2010. The CSA Technical Committee approved the proposed harmonized standard for non-metallic dip tubes for use in water heaters by letter ballot dated May 12, 2011.The first edition of the harmonized Z21/CSA

36、Standard for Non-metallic dip tubes for use in water heaters, Z21.98 CSA 4.10,was approved by the Canadian Interprovincial Gas Advisory Council on March 19, 2012 and by the American National Standards Institute, Inc., on March 30, 2012.The second edition of the harmonized Z21/CSA Standard for Non-me

37、tallic dip tubes for use in water heaters, ANSI Z21.98 CSA 4.10, was approved by the Canadian Interprovincial Gas Advisory Council on August 4, 2014, and by the American National Standards Institute, Inc., on June 24, 2014.This, the third edition of the harmonized Z21/CSA Standard for Non-metallic d

42、use in water heaters.1.2 Compliance of a dip tube with this Standard does not imply that such dip tube is acceptable for use in water heaters without supplemental tests with the dip tube installed in the particular water heater design.1.3 This standard contains SI (Metric) corresponding to the yard/

43、pound quantities, the purpose being to allow the Standard to be used in SI (Metric) units. (American National Standard for Metric Practice, IEEE/ASTM SI 10, or ISO 80000-1:2009, Quantities and units Part 1: General, is used as a guide in making metric conversion from yard/pound quantities.) If a val

44、ue for a measurement and a corresponding value in other units are stated, the first stated value is to be regarded as the requirement. The given corresponding value may be approximate. If a value for a measurement and a corresponding value in other units are both specified as a quoted marking requir

45、ement, the first stated unit, or both, are to be provided.1.4 In this Standard, “shall” is used to express a requirement, i.e., a provision that the user shall satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “m

46、ay” 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 ta
