Overview

ASTM F949-20 is the internationally recognized standard specification developed by ASTM for poly(vinyl chloride) (PVC) corrugated sewer pipe with a smooth interior and associated fittings. This standard outlines the requirements, test methods, and materials for manufacturing high-quality PVC corrugated pipes ranging from 4 to 48 inches in diameter, specifically for underground, nonpressure applications. These include use in sanitary sewers, storm sewers, and subdrainage systems, both perforated and unperforated.

The dual-wall profile design-an outer corrugated wall fused to a smooth inner wall-provides strength, flexibility, and efficient flow characteristics. Compliance with ASTM F949-20 ensures effective performance, durability, and safety in municipal, commercial, and construction drainage systems.

Key Topics

• Material Specifications: Pipes and fittings must be manufactured from PVC compound with a minimum cell classification as defined in ASTM D1784.
• Pipe Design: Dual-wall construction combines a corrugated exterior for strength with a smooth interior to optimize flow and facilitate cleaning.
• Sizes and Stiffness: Covers pipes from 4 to 48 inches, with standardized pipe stiffness levels available at 46 psi and 115 psi for various load requirements.
• Joints and Fittings: Includes details for gasketed and solvent-cemented joints to ensure leak-tight performance. Fittings may be molded or fabricated, ensuring compatibility and ease of installation.
• Testing and Quality Control: Specifies dimensional, physical, and performance tests, such as:
  • Pipe stiffness
  • Flattening resistance
  • Impact strength
  • Extrusion quality
  • Heat reversion
  • Bond strength between layers
  • Joint tightness
• Manufacturing Tolerances: Ensures uniformity in dimensions, perforation sizes (for subdrainage pipes), and wall thickness for reliable system functionality.
• Marking and Identification: All pipes and fittings must display manufacturer information, pipe dimensions and classification, standard designation, material type, and production codes for full traceability.

Applications

ASTM F949-20 PVC corrugated sewer pipe delivers reliable solutions for a range of nonpressure, underground applications, including:

• Sanitary Sewer Systems: Used for transporting wastewater safely below ground, providing long-term corrosion resistance and smooth flow properties.
• Storm Sewer Infrastructure: Ideal for managing surface water runoff due to impact resistance and high structural integrity under soil loads.
• Subdrainage Systems: Available in perforated and unperforated varieties, these pipes effectively manage groundwater, helping to prevent soil saturation around foundations, roadways, and landscapes.
• Municipal and Commercial Installations: Frequently specified by utilities, DOTs, and civil engineers for new installations and rehabilitation of existing infrastructure.
• Environmentally Sensitive Sites: Non-corrosive material and leakproof joints reduce risk of environmental contamination.
• Special Considerations: For industrial waste lines, chemical resistance and temperature limits (up to 140°F/60°C) should be verified in consultation with local authorities.

ASTM F949-20 compliant pipes must be installed following ASTM D2321 to ensure long-term performance, especially regarding embedment material selection and proper backfill.

1. Scope*
1.1 This specification covers requirements, test methods, and materials for 4 to 48 in. diameter poly(vinyl chloride) (PVC)
corrugated pipe with a smooth interior. This profile wall pipe consists of an outer corrugated wall fused to a smooth inner wall
providing pipe stiffness levels of 46 psi and 115psi.115 psi. Joints and fittings are included in this specification.
1.2 The requirements of this specification are intended to provide pipe and fittings suitable for underground use in nonpressure
applications for sanitary sewers, storm sewers, and perforated and unperforated pipes for subdrainage.
NOTE 1—Industrial waste disposal lines should be installed only with the specific approval of the cognizant code authority, since chemicals not
commonly found in drains and sewers and temperatures in excess of 140°F (60°C)140 °F (60 °C) may be encountered.
1.3 Pipe and fittings produced to this specification shall be installed in accordance with Practice D2321.
NOTE 2—For perforated pipe applications, the size of the embedment zone and permeability of the embedment material are important to the system’s
ability to provide the desired level of infiltration or exfiltration. The gradation of the embedment material must be compatible with the perforation slot
size to avoid backfill migration into the pipe.
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical
conversions to SI units that are provided for information only and are not considered standard.
1.5 The following precautionary caveat pertains only to the test method portion, Section 7, 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.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization
