1、 Prefabricated Plastic Spa Shells IAPMO/ANSI Z124.7-2013 American National Standard Approval of an American National Standard requires verification by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer. Consensus is establi

2、shed when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be con

3、sidered, and that a concerted effort be made toward their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing, or using products, p

4、rocesses, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an

5、American National Standard in the name of the American National Standards Institute. Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on the title page of this standard. CAUTION NOTICE: This American National Standard may be revised or withdrawn at an

6、y time. The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard. Purchasers of American National Standards may receive current information on all standards by calling or writing the American National Standar

It supersedes the previous edition, published in 1997. This Standard was developed by the IAPMO Z124 Technical Su

13、bcommittee and approved by the IAPMO Plumbing Standards Committee in accordance with the American National Standards Institute (ANSI) Essential Requirements: Due process requirements for American National Standards and the IAPMO Policies and Procedures for Consensus Development of American National

14、Standards. This Standard was approved as an American National Standard on January 29, 2013. Notes: (1) The use of the singular does not exclude the plural (and vice versa) when the sense allows. (2) This standard was developed in accordance with the IAPMO procedures accredited as meeting the criteri

15、a for American National Standards and it is an American National Standard. The IAPMO Standards Committee that approved this Standard was balanced to assure that individuals from competent and concerned interests had an opportunity to participate. During its development, this Standard was made availa

16、ble for public review, thus providing an opportunity for additional input from industry, academia, regulatory agencies, and the public at large. (3) This Standard was developed by consensus, which is defined as substantial agreement; consensus implies much more than a simple majority, but not necess

17、arily unanimity. It is consistent with this definition that a member of the IAPMO Plumbing Standards Committee can be included in the Committee list and yet not be in full agreement with all sections of this Standard. (4) Although the intended primary application of this Standard is stated in its sc

18、ope, it is important to note that it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose. (5) IAPMO Standards are subject to periodic review and suggestions for their improvement will be referred to the IAPMO Plumbing Standards Committee. To

19、submit a proposal for change to this Standard, you may send the following information to the International Association of Plumbing and Mechanical Officials, Attention Standards Department, 5001 East Philadelphia Street, Ontario, California, 91761, and include “Proposal for change” in the subject lin

20、e: (a) standard designation (number); (b) relevant section, table, or figure number, as applicable; (c) wording of the proposed change, tracking the changes between the original and the proposed wording; and (d) rationale for the change. (6) Requests for interpretation should be clear and unambiguou

21、s. To submit a request for interpretation of this Standard, you may send the following information to the International Association of Plumbing and Mechanical Officials, Attention Standards Department, 5001 East Philadelphia Street, Ontario, California, 91761, and include “Request for interpretation

22、” in the subject line: (a) edition of the standard for which the interpretation is being requested; (b) definition of the problem, making reference to the specific section and, when appropriate, an illustrative sketch explaining the question; (c) an explanation of circumstances surrounding the actua

23、l field conditions; and (d) the request for interpretation phrased in such a way that a “yes” or “no” answer will address the issue. (7) Interpretations are processed in accordance with IAPMOs accredited standards development procedures. IAPMO issues written replies to inquiries concerning interpret

24、ation of technical aspects of this Standard. (8) IAPMO accepts responsibility only for those interpretations of this Standard issued in accordance with the accredited IAPMO policies and procedures, which precludes the issuance of interpretations by individuals. (9) IAPMO does not “approve,” “rate,”

25、or “endorse” any item, construction, proprietary device, or activity. IAPMO/ANSI Z124.72013 Prefabricated Plastic Spa Shells February 2013 iii (10) IAPMO does not take any position with respect to the validity of any patent rights asserted in connection with any items mentioned in this Standard, and

26、 does not undertake to insure anyone utilizing this Standard against liability for infringement of any applicable patents, nor assumes any such liability. Users of this Standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such r

27、ights, are entirely their responsibility. (11) Participation by federal agency representative(s) or person(s) affiliated with industry is not to be interpreted as government or industry endorsement of this Standard. (12) Attention is drawn to the possibility that some of the elements of this Standar

28、d may be the subject of patent rights. IAPMO is not to be held responsible for identifying any or all such patent rights. Users of this Standard are expressly advised that determination of the validity of any such patent rights is entirely their responsibility. IAPMO/ANSI Z124.72013 Prefabricated Pl

Notes accompanying

33、sections in the body of the Standard do not specify requirements or alternative requirements; their purpose is to separate explanatory or informative material from the text. Notes to tables and figures are considered part of the table or figure and can be written as requirements. 1.4 SI units are th

34、e primary units of record in global commerce. In this Standard, the inch/pound units are shown in parentheses. The values stated in each measurement system are equivalent in application but each unit system is to be used independently. Combining values from the two measurement systems can result in
