Standard Specification for Rigid Poly(Vinyl Chloride) (PVC) Exterior-Profile Extrusions Used for Assembled Windows and Doors
ABSTRACT
This specification establishes requirements for the material properties, including dimensional stability, weatherability, and extrusion quality, of rigid poly(vinyl chloride) (PVC) exterior profile extrusions used for assembled windows and doors. Methods for testing and for identifying exterior profile extrusions that comply with this specification are also provided. The physical and performance requirements of PVC are presented in details. The dimensional stability and impact strength shall be tested to meet the requirements prescribed.
SCOPE
1.1 This specification establishes requirements for the material properties, including dimensional stability, weatherability, and extrusion quality, of rigid poly(vinyl chloride) (PVC) exterior profile extrusions used for assembled windows and doors. Methods for testing and for identifying exterior profile extrusions that comply with this specification are also provided.
1.2 The use of rigid PVC recycled plastic in this product shall be in accordance with the requirements in Section 6.
Note 1: Information with regard to application, assembly, and installation should be obtained from the manufacturers of the profiles and of the windows and doors.
Note 2: Refer to Specification D3678 for interior profile extrusions.
1.3 Color-hold guidelines are provided in an appendix for the manufacturer’s product development and quality performance use.
1.4 Color-hold guidelines are presently limited to white, grey, beige, light brown, and dark brown (see Figs. X1.1 through X1.5). Additional colors will be added as color guidelines are developed.
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are for information only.
Note 3: There is no known ISO equivalent to this standard.
1.6 The text of this standard references notes and footnotes, which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this standard.
1.7 The following safety hazards caveat pertains only to the test methods portion, Section 11, of this specification: 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
