1. Scope
1.1 This specification establishes requirements for the ma- terial properties and physical properties, including dimensional tolerances, extrusion quality, and weatherability, of rigid poly vinyl-chloride (PVC) exterior profiles used for agricultural, commercial, residential fencing and railing. Methods for test- ing and for identifying exterior profile extrusions that comply with this specification are also provided. N OTE 1—Information with regard to application, assembly, and instal- lation should be obtained from the manufacturer or in accordance with Practice F1999, or both. N OTE 2—Loadbearing characteristics for fence and railing assemblies are not addressed within this specification (for example, windload, horizontal or vertical guardrail loading). 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 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 appro- priate safety, health, and environmental practices and deter- mine the applicability ofregulatory limitations prior to use. 1.5 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
3. Terminology
3.1 General—Definitions are in accordance with Terminolo- gies D883 and D1600, unless otherwise indicated. 3.2 Definitions ofTerms Specific to This Standard:3.2.1 capstock—the outer layer in a coextrusion exposed to weathering. 3.2.2 coextrusion—the process of coextruding profiles from two or more concentric streams of PVC compounds. N OTE 3—Separate PVC materials may be coextruded to form a multi-layered profile with each layer having different physical character- istics such as strength and weathering. 3.2.3 color-hold guidelines—predictive target color regions within a three-dimensional model which constitute acceptable appearance retention levels of color change resulting from weathering of specific product type and color. N OTE 4—Commercial products which demonstrate weathering behavior within reasonable conformance to these target guidelines during a 2–year test period can be anticipated to weather without exhibiting unacceptable color changes during the service life of the product. 3.2.4 longitudinal bow—refers to bow along the span. Lon- gitude is measured along the span. 3.2.5 reworked material—material from the manufacturer’s facility of known, compatible composition meeting the mate- rial requirement of this specification that has been reground, pelletized, or solvated after having been previously processed by molding, extrusion, and so forth. 3.2.6 single layer profile—profiles extruded from a single PVC compound. Weathering and other physical characteristics are uniform throughout the profile. 3.2.7 substrate—inner layer(s) of a coextrusion not exposed to weathering. 3.2.8 temperate northern climate—in weather testing, a North American metropolitan area testing site located within 73 to 100° W longitude and 37 to 45° N latitude.
4. Significance and Use
4.1 The purpose of this specification is to establish a recognized standard of quality for rigid poly vinyl chloride (PVC) exterior profiles for use in assembling agricultural, commercial, and residential fencing and railing. The term “PVC fence” refers to complete fencing and railings systems in which the primary structural members such as posts, rails, spindles, pickets, and gates are made from PVC exterior profiles. Accessory components (not included in this specification), including bolts, screws, hinges, latches, caps, and brackets, may be made from PVC or non-PVC materials, or both. The information contained in this specification is intended to be helpful to producers, distributors, and users and to promote understanding between purchasers and sellers.
