Full title and description

Standard Specification for Nonreinforced Concrete Specified Strength Culvert, Storm Drain, and Sewer Pipe — ASTM C985-22. This manufacturing and purchase specification describes nonreinforced concrete pipe produced to specified strengths for use in culverts, storm drainage, and sanitary sewer conveyance; it includes requirements for strength and load testing but does not prescribe bedding or installation practices.

Abstract

This specification covers nonreinforced concrete pipe designed for specified strengths and intended for the conveyance of sewage, industrial wastes, and storm water and for construction of culverts. Strength tests and load tests are specified to verify the designated strengths; a metric companion standard (C985M) is available. The document is concise (short-form purchase/manufacturing standard) and is intended to be used together with appropriate installation and construction practice documents.

Scope

Specifies requirements for nonreinforced concrete culvert, storm drain, and sewer pipe manufactured to specified strength classifications. The scope clarifies that the standard is a manufacturing/purchase specification (it does not define bedding, backfill, or prescribe relationships between field loads and pipe strength) and points users to correlate pipe strength selection with expected field conditions and installation practices. A metric counterpart, C985M, is published for SI-unit usage.

Key topics and requirements

• Designation and classification of nonreinforced concrete pipe by specified strength (three-edge-bearing and other strength tests).
• Requirements for strength testing and load testing to verify specified pipe strength.
• Manufacturing and purchase provisions (tolerances, acceptance testing) rather than installation guidance.
• Reference to a metric companion standard (C985M) for SI units.
• Notes and cautions that proper performance depends on selecting appropriate pipe strength, bedding, and backfill — owner/engineer responsibility to correlate field requirements with specified strength.

Typical use and users

Used by pipe manufacturers, municipal and highway engineers, specifying agencies, procurement officers, and contractors when specifying or purchasing nonreinforced concrete culvert, storm drain, or sewer pipe where specified-strength (nonreinforced) sections are appropriate. Also used as a reference in procurement documents and quality-assurance testing programs. Engineers typically combine this specification with installation and bedding guidance from project specifications or other ASTM/industry standards.

Related standards

Commonly associated with or used alongside other ASTM concrete-pipe and joint standards (examples include the metric companion C985M-22 and related pipe/joint specifications and test methods referenced in the concrete-pipe family). Standards that often appear in the same technical context include various ASTM pipe/specification documents and joint/seal standards used on installations. For cross-references and specific normative relationships consult the full ASTM record for C985 and the C13 committee listings.

FAQ

Q: What is this standard?

A: ASTM C985-22 is the ASTM Standard Specification for Nonreinforced Concrete Specified Strength Culvert, Storm Drain, and Sewer Pipe — a short manufacturing/purchase specification that sets strength and testing requirements for nonreinforced concrete pipe.

Q: What does it cover?

A: It covers the designation of specified-strength, nonreinforced concrete pipe and the strength/load testing required to demonstrate compliance. It does not cover bedding, backfill, or detailed installation procedures; those are project-specific and must be selected to match the chosen pipe strength.

Q: Who typically uses it?

A: Pipe manufacturers, design and municipal engineers, purchasing/specification writers, contractors, and testing laboratories involved in production acceptance and purchaser acceptance testing for nonreinforced concrete pipe.

Q: Is it current or superseded?

A: As published in 2022 the designation is C985-22 and is listed as active; users should confirm the current status on the official ASTM record if they need the very latest revision or amendments.

Q: Is it part of a series?

A: It is part of the ASTM concrete-pipe and precast concrete product family and has a metric companion (C985M-22). It is used in the same ecosystem as related pipe and joint standards maintained by ASTM Committee C13.

Q: What are the key keywords?

A: Nonreinforced concrete pipe; culvert; storm drain; sewer pipe; specified strength; three-edge-bearing; strength test; load test; C985M; ASTM C985-22.
