Such products shall meet therequirements as outlined in this standard.While this standard covers the performance require-ments of plastic bathtub or shower units and describes theseperformance requirements in terms of methods of

17、 testapplicable to all such units, a number of different materialsand methods of manufacture shall be permitted to be used tomeet these requirements. Each of these materials and meth-ods have different properties which will affect its end per-formance and suitability for the intended use. For this r

18、ea-son, portions of the standard are broken into separaterequirements designed to identify these individual charac-teristics.The materials and equipment which are listed as havingbeen used to conduct the testing procedures in this standardare provided solely for informational reference. Materialsand

19、 equipment of similar design, composition and specifica-tion shall only be used to conduct these testing procedureswhen they produce equivalent results.1.2 Purpose. The purpose of this standard is to establishminimum performance requirements for plastic bathtub orshower units.Conformance to this sta

20、ndard and test procedures here-in shall indicate the acceptability of a plastic bathtub orshower unit as a plumbing fixture.1.3 Normative referencesThe following standards contain provisions which, throughreference in this text, constitute provisions of this AmericanNational Standard.

The units shall be made of suit-able grades of plastic resins and such other filling, coloring,reinforcing, and coating materials as will meet the perfor-mance requirements of this standard.2.1.2 Finish. The finished surface of the unit shall beof a quality which meets all of the applicable requir

26、ementsof the standard. Six common types of plastic finishes shallbe as defined. (1) Type 1 - No separate surface finish: The surfacefinish is the same as, and is usually integral with, the struc-tural base. (Excluding Type 4.)(2) Type 2 - Coated surface finish: These units arecharacterized by the pr

27、esence of a surface coating which isapplied to the structural base either prior to or after themolding process. (Excluding Type 4.)1IAPMO/ANSI Z124.1.2-2005 Licensed to Sarah Zhou.

28、3 - Shell-coated surface finish: These unitsare characterized by the presence of a thermoplastic sheetmaterial which is thermoformed and to the back of which astructural base is applied.(4) Type 4 - Cast Filled Polymers: These units arecharacterized by their composition and manufacturingprocess; whe

29、reby polymers are filled with particulates, act-ing as both structural and decorative elements, and are castinto a complete bathtub with or without a pre-coated finish. (5) Type 5 - Laminated Finish: A thermoplastic sur-face co-extruded, adhesive bonded, or otherwise adhered toa thermoplastic substr

(6) Type 6 - Flexible Core Constructi on: A combina-tion of materials comprising a flexible core, faced on bothsides with other materials.2.1.3 Supporting structure. The material of the support-ing structure in

31、tegral with the unit and its attachment shallbe adequate to meet the performance requirements of thisstandard.2.2 Dimensional tolerances. The finished trim dimension-al tolerances for units shall be the manufacturers stated“rough-in”dimensions.2.3 Units for testing. Units to be inspected and testeds

32、hall be taken from finished-goods inventory. 2.4 Installation instructions. Each unit shall be suppliedwith a copy of the manufacturers written installationinstructions, unless intended to be installed by the manufac-turer.2.5 Care and maintenance instructions. Each unit shallbe supplied with a copy

33、 of the manufacturers written careand maintenance instructions affixed to the unit in a con-spicuous location and shall state, “To be removed for useby the occupant.”2.6 Identification.
