This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: D3678 − 14 D3678 − 19 An American National Standard
Standard Specification for
Rigid Poly(Vinyl Chloride) (PVC) Interior-Profile Extrusions
This standard is issued under the fixed designation D3678; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope*
1.1 This specification establishes requirements for the material properties, including dimensional stability and extrusion quality,
of rigid, poly(vinyl chloride) (PVC) interior-profile extrusions. Methods for identifying interior-profile extrusions that comply with
the requirements of this specification are provided.
1.2 Use of rigid PVC recycled plastic is permitted in accordance with the requirements of Sections 6 and 7.
1.3 Rigid PVC compounds for interior building product applications are covered in Specification D1784.
1.4 Rigid PVC exterior profile extrusions for assembled windows and doors are covered in Specification D4726.
1.5 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.
1.6 The values stated in SI units are to be regarded as the standard. The values given in parentheses are given for information
only.
NOTE 1—Information with regard to application should be obtained from the manufacturers of the profiles.
NOTE 2—There is no known ISO equivalent to this standard.
1.7 The following precautionary caveat pertains only to the test method portion, Section 8, 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 safety, health, and healthenvironmental 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.

3. Terminology
3.1 General—Defintions are in accordance with Terminology D883 or Terminology E631 and abbreviations with Terminology
D1600, unless otherwise indicated.
4. Significance and Use
4.1 The purpose of this specification is to establish on a national basis, a recognized standard of quality for rigid poly(vinyl
chloride) (PVC) interior-profile extrusions for interior use other than cellular products, piping, tubing, and window and door
profiles used in finished building products. The information contained in this standard is intended to be helpful to producers,
distributors, and users, and to promote understanding between buyers and sellers. users. It is also intended to serve as the basis
for requirements on finished interior building products which are either made from or employ rigid PVC profile extrusions in their
construction.
5. Classification
5.1 This standard covers three classes of rigid PVC interior-profile extrusions as follows:
Class 1—Normal impact
Class 2—Intermediate impact
Class 3—High impact
6. Materials and Manufacture
6.1 This specification covers profile extrusions made from plastics conforming to the requirements of Specification D1784. ,
Table 1. Class 1 extrusions shall meet the requirements specified in Specification D1784for Class 12454 compound. Class 2
extrusions shall meet the requirements for Class 14323 compound. Class 3 extrusions shall meet the requirements for Class
1-40031-54-0000 compound. Refer to Table 1 in Specification 15223 compound.D1784.
6.2 Use of rigid PVC recycled plastic, as defined in Guide plastic D7209is permitted in this product if all the requirements in
the sections on Materials and Manufacture (Section 6), and on Physical Requirements (Section 7) are met by the extrusions
containing PVC recycled plastic.
-5 -5
6.3 All Class compounds shall have a minimum coefficient of linear expansion of 10 × 10 cm ⁄cm ⁄°C (5.5 × 10 in. ⁄in. ⁄°F).
NOTE 3—Non-PVC materials may be used as a capstock.
6.4 Rework Material—Clean, homogeneous PVC rework material or rework material containing PVC capstock generated from
the manufacturer’s own production of the same class compound is permitted for use by the same manufacturer provided that the
extruded profiles meet all the requirements of this specification. Clean principally PVC rework material containing non-PVC
capstock is permitted for use only in the substrate of a capstocked product by the same m
