Overview

ASTM F1760-16(2020) is an international standard published by ASTM International, providing requirements for coextruded Poly(Vinyl Chloride) (PVC) non-pressure plastic pipe that incorporates reprocessed-recycled content. Developed in response to regulatory guidelines on federal procurement of recycled-content materials, this standard is crucial for manufacturers, engineers, and organizations seeking sustainable piping solutions that meet performance and quality benchmarks.

The specification focuses on multi-layer coextruded PVC pipes featuring:

• An inner and outer layer made from virgin PVC compound
• A center layer containing reprocessed and/or recycled PVC content

This coextruded structure is intended for non-pressure applications, encompassing three primary pipe series: Sewer-Drain series, IPS Schedule 40, and IPS Pipe Stiffness (PS) series. ASTM F1760 ensures that recycled-content pipes can be reliably used in a variety of construction, drainage, and utility applications.

Key Topics

• Pipe Construction

  • Three-layer coextruded PVC pipe: inner and outer virgin PVC layers with a recycled PVC center layer
  • Multi-layer coextrusion die process

• Recycled Content

  • Internal, external, and post-consumer recycled PVC allowed in the center layer only
  • Post-consumer recycled content limited to 60% by weight of center layer

• Pipe Series and Uses

  • Sewer-Drain series (PSM outside diameter, 46 psi stiffness) for sewers and drains
  • IPS Schedule 40 for underground drain, waste, and vent
  • IPS Pipe Stiffness (PS) series (100 psi and 120 psi stiffness) for underground communications and electrical distribution

• Quality and Performance Requirements

  • Mechanical integrity: impact resistance, bond integrity, flattening, and layer uniformity
  • Dimensional compliance: wall thickness, diameter, and roundness per specification tables
  • Joint integrity: solvent-cement and elastomeric-gasket joints must pass pressure and leak-tightness tests

• Marking and Traceability

  • Mandatory marking indicating compliance, manufacturer, recycled PVC content, pipe size, and production details

Applications

This standard is referenced by government agencies, contractors, and engineers when specifying environmentally responsible piping for non-pressure systems. Key application areas include:

• Municipal Sewer and Drainage Systems
  Sewer-Drain series pipes are commonly used for underground municipal sewer, stormwater, and drain installations.

• Building Construction and Plumbing
  IPS Schedule 40 series pipes provide reliable solutions for drainage, waste, and vent piping below ground within building projects.

• Underground Utilities
  IPS Pipe Stiffness (PS) series pipes are suitable for direct burial in electrical and communication conduit systems, offering strength and durability with a recycled PVC layer.

By complying with ASTM F1760, organizations support procurement policies favoring recycled content, reduce environmental impact, and ensure robust product quality for non-pressure applications.

Related Standards

ASTM F1760 cross-references several other standards relevant to PVC pipe manufacturing and testing, including:

• ASTM D1784 - Rigid PVC Compounds and Chlorinated PVC Compounds
• ASTM D3034 - Type PSM Poly(Vinyl Chloride) Sewer Pipe and Fittings
• ASTM D2466 / D2467 - PVC Fittings (Schedule 40 and 80)
• ASTM D2665 - PVC Drain, Waste, and Vent Pipe and Fittings
• ASTM F477 - Elastomeric Seals (Gaskets) for Joining Plastic Pipe
• ASTM D2122, D2412, D2444 - Test methods for dimensions, external loading, and impact resistance
• ASTM D3212 - Joints for Drain and Sewer Plastic Pipes Using Flexible Elastomeric Seals

By following ASTM F1760 in conjunction with these related standards, the manufacture and installation of coextruded, recycled-content PVC pipe is assured to meet both sustainability and performance objectives.
