1. Scope and purpose
1.1 Scope. This standard covers requirements and test methods for performance of materials and workmanship, and finish of plastic lavatory units manufactured as a sepa- rate bowl or a bowl with integral top. While this standard covers the performance require- ments of plastic lavatory units and describes these perfor- mance requirements in terms of methods of test applicable to all such units, a number of different materials and meth- ods of manufacture shall be permitted to be used to meet these requirements. Each of these materials and methods have different properties which will affect its end performance and suitability for the intended use. For this reason, portions of the standard are broken into separate requirements designed to identify these individual characteristics.
The materials and equipment which are listed as having been used to conduct the testing procedures in this standard are provided solely for informational reference. Materials and equipment of similar design, composition and specification shall only be used to conduct these testing procedures when they produce equivalent results.
1.2 Purpose. The purpose of this standard is to establish minimum performance requirements for plastic lavatory units. Conformance to this standard and test procedures here- in shall indicate the acceptability of a plastic lavatory unit as a plumbing fixture.
1.3 Normative references. The following standards con- tain provisions which, through reference in this text, consti- tute 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 encouraged to investigate the possibility of applying most recent edi- tions of the standards indicated below.
2. General requirements
2.1 Materials
2.1.1 Composition. The units shall be made of suit- able grades of plastic resins and any such other filling, col- oring, reinforcing, and coating materials as will meet the performance 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. Five common types of plastic finishes shall be as defined: (1) Type 1 – No separate surface finish: The surface fin- ish is the same as, and is usually integral with, the structural base. (Excluding Types 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. (Excluding Type 4.)
