3、 by the standards developer. Consensus is established when, in the judgement of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected inter- ests. Substantial agreement means much more than a simple majority, but not necessari- ly unanimity. C
4、onsensus requires that all views and objections be considered, 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 manu
5、facturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no cir- cumstances give an interpretation of any American National Standard. Moreover, no person shall have
6、the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute. Requests for inter- pretations should be addressed to the secretariat or sponsor whose name appears on the title page of this standard. CAUTION NOTICE: This Am
7、erican National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard.

Such products shall meet the requirements as outlined in this standard. While this standard covers the performance require-
17、 ments of plastic bathtub or shower units and describes these performance requirements in terms of methods of test applicable to all such units, a number of different materials and methods of manufacture shall be permitted to be used to meet these requirements. Each of these materials and meth- ods
18、have different properties which will affect its end per- formance and suitability for the intended use. For this rea- son, portions of the standard are broken into separate requirements designed to identify these individual charac- teristics. The materials and equipment which are listed as having be
19、en used to conduct the testing procedures in this standard are provided solely for informational reference. Materials and equipment of similar design, composition and specifica- tion shall only be used to conduct these testing procedures when they produce equivalent results. 1.2 Purpose. The purpose
20、 of this standard is to establish minimum performance requirements for plastic bathtub or shower units. Conformance to this standard and test procedures here- in shall indicate the acceptability of a plastic bathtub or shower unit as a plumbing fixture. 1.3 Normative references The following standar
21、ds contain provisions which, through reference in this text, constitute provisions of this American National Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this American National Standard are encourag
22、ed to investigate the possibility of applying most recent editions of the standards indicated below.

The units shall be made of suit- able grades of plastic resins and such other filling, coloring, reinforcing, and coating materials a
26、s will meet the perfor- mance requirements of this standard. 2.1.2 Finish. The finished surface of the unit shall be of a quality which meets all of the applicable requirements of the standard. Six common types of plastic finishes shall be as defined. (1) Type 1 - No separate surface finish: The sur
27、face finish is the same as, and is usually integral with, the struc- tural base. (Excluding Type 4.) (2) Type 2 - Coated surface finish: These units are characterized by the presence of a surface coating which is applied to the structural base either prior to or after the molding process.
