ASTM C822-21 PDF

Overview

ASTM C822-21: Standard Terminology Relating to Concrete Pipe and Related Products establishes a comprehensive set of definitions and terminology used within the concrete pipe industry. Developed by ASTM Committee C13, this standard provides clarity and uniformity in the language used for concrete pipe, box sections, manholes, joint components, and the associated testing and design methods. Adherence to clear terminology is crucial for engineers, manufacturers, specifiers, and regulators for effective communication and compliance across all phases of design, production, testing, and installation of concrete pipe products.

Key Topics

ASTM C822-21 covers a wide range of terminology and concepts relevant to concrete pipe and related infrastructure components:

• Fundamental Terms
  • Definitions for concrete pipe, box sections, manholes, and fittings.
  • Terminology for structural aspects such as reinforcement, wall, top slab, and base.
• Testing and Performance Criteria
  • Terms for key test methods including absorption test, compression test, hydrostatic test, permeability test, joint leakage test, and low-pressure air test.
  • Definitions of minimum and ultimate strength, D-load, and other performance metrics.
• Manufacturing and Installation
  • Vocabulary pertaining to manufacturing processes, such as admixture, batching, and production run.
  • Installation-related terms including laying length, installed length, joint deflection, manhole base, and lift hole.
• Joint and Structure Components
  • Detailed definitions for male/female pipe ends (spigot, bell, groove, tongue), sealing mechanisms, O-ring gaskets, joints, sealing bands, and resilient connectors.
• Hydraulic and Environmental Considerations
  • Gradation, permeability, infiltration, exfiltration, and inflow.
  • Definitions covering the use of concrete pipes in drainage, sewer, irrigation, and stormwater applications.

Recent revisions reflect updated definitions for critical industry terms such as "concrete", "owner", "laying length", "manufactured length", "reinforced concrete pipe", and "reinforcement", ensuring alignment with industry advances and best practices.

Applications

ASTM C822-21 supports practical use in a variety of civil engineering and infrastructure projects by:

• Facilitating Clear Communication Ensuring that project teams, contractors, suppliers, and regulators have a common understanding of technical terms minimizes errors and misinterpretations during design, procurement, testing, and installation.
• Supporting Specification and Compliance The standard provides a reference point for contract documents, construction specifications, quality assurance protocols, and regulatory compliance, particularly for projects involving concrete sewers, culverts, storm drains, and manholes.
• Guiding Product Testing and Quality Control By standardizing terminology for test methods and structural requirements, ASTM C822-21 aids in consistent application and reporting of quality assurance tests such as compressive strength, absorption, hydrostatic, and leakage tests.
• Regulating International and Domestic Trade Uniform terminology facilitates the exchange of products and services across different regions and regulatory environments, supporting global trade and procurement.

Related Standards

ASTM C822-21 is frequently used in conjunction with related ASTM standards and industry references, including:

• ASTM C497 - Test Methods for Concrete Pipe, Concrete Box Sections, Manhole Sections, or Tile
• Standards developed by ASTM Committee C13 on Concrete Pipe
• American Association of State Highway and Transportation Officials (AASHTO) standards relating to concrete structures and pipelines
