    (What is a Work Item?)

    Developed by Subcommittee: F14.30 | Committee F14 | Contact Staff Manager



    WK71128

    1. Scope

    1.1 This specification establishes requirements for the material properties and physical properties, including dimensional tolerances, extrusion quality, and weatherability, of rigid poly (vinyl chloride) (PVC) exterior profiles used for sound walls. Methods for testing and for identifying exterior profile extrusions that comply with this specification are also provided. In addition, requirments for flexural capacity and product installation are given. NOTE 1Information with regard to application, assembly, and installation should be obtained from the manufacturer. 1.2 The material used in these exterior profiles is limited to rigid poly (vinyl chloride) (PVC) compounds in a single homogeneous extrusion or in a coextrusion of two or more PVC compounds in distinct layers. 1.3 Units--The values stated in inch-pound units are to be regarded as the standard. The values in parentheses are provided for information only. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

    Rationale

    Many miles of PVC sound walls are constructed along freeways every year. However, there are no comprehensive national standards governing material and physical properties, tolerances, quality, weatherability, and other issues. The new standard should prove useful to Departments of Transportation, highway design firms, and contractors.

    The title and scope are in draft form and are under development within this ASTM Committee.
