Full title and description

Standard Specification for Rigid Poly(Vinyl Chloride) (PVC) Interior-Profile Extrusions — specification establishing minimum material and extrusion requirements for rigid PVC interior-profile extrusions used in interior building products, including criteria for dimensional stability, extrusion quality and identification of compliant products.

Abstract

This specification (D3678-19) defines three classes of rigid PVC interior-profile extrusions and sets out material-property requirements, dimensional and processing tolerances, and methods to identify extrusions that meet the specification. It is intended for producers, distributors and users of rigid PVC profile extrusions for interior applications (excluding cellular products, piping, tubing and window/door profiles).

General information

• Publisher: ASTM International.
• ICS / categories: 83.080.20 (Thermoplastic materials) — plastics/building products.

Scope

This specification establishes requirements for the material properties and extrusion quality of rigid PVC interior‑profile extrusions intended for interior use. It covers three classes of rigid PVC extrusions and provides methods for identifying extrusions that comply with the specification; it does not apply to cellular PVC products, piping, tubing, or window and door profiles used in finished fenestration products.

Key topics and requirements

• Definition and classification of three classes of rigid PVC interior-profile extrusions.
• Material-property requirements (including dimensional stability and physical properties relevant to interior use).
• Extrusion quality and dimensional tolerances for profile geometry.
• Identification and acceptance criteria and basic compliance/inspection methods.
• Referenced conditioning and test practices (see ASTM referenced documents for conditioning and related test methods).

Typical use and users

Used by manufacturers of rigid PVC interior trim, base, casing, molding and other interior profile extrusions; product designers, specifiers, quality managers, procurement teams and code compliance personnel in the building-products and plastics industries who need a brief, standardized material and extrusion specification for interior PVC profiles.

Related standards

The specification references and is used alongside other ASTM plastics and building‑product standards (examples include ASTM practices for conditioning plastics and related PVC building‑product test methods). Users commonly consult adjacent D20 committee standards for detailed test methods and product performance standards when specifying or testing PVC building products.

FAQ

Q: What is this standard?

A: ASTM D3678‑19 is a short specification that sets minimum material and extrusion requirements for rigid poly(vinyl chloride) interior‑profile extrusions used in interior building applications.

Q: What does it cover?

A: It covers classification of three classes of rigid PVC interior profiles, material-property requirements (including dimensional stability), extrusion quality and basic identification/acceptance methods; it excludes cellular products, piping, tubing and window/door profiles.

Q: Who typically uses it?

A: Manufacturers, quality and production engineers, product specifiers, procurement specialists and compliance personnel in the plastics and building-products sectors specifying or verifying rigid PVC interior profiles.

Q: Is it current or superseded?

A: The D3678‑19 edition is the 2019 revision (designation D3678‑19) and is the current ASTM edition for this specification; check ASTM or national catalogues for any later revisions or reapprovals if exact up‑to‑date status is required.

Q: Is it part of a series?

A: It is maintained under ASTM Committee D20 (Plastics) and is used in the context of other D20 standards covering PVC materials and test methods; it is a standalone specification rather than a numbered series but is related to other ASTM plastics/building‑product standards for testing and performance.
