ASTM C923/C923M is the ASTM standard for resilient connectors between reinforced concrete manhole structures, pipes, and laterals. It is used to define a consistent basis for connector performance and product evaluation where watertight, flexible, and durable joints are needed in buried utility systems. For engineers, specifiers, and procurement teams, this standard helps support better material selection and quality control when selecting connectors for manhole-to-pipe and lateral connections.

Overview of ASTM C923/C923M

The official title, Standard Specification for Resilient Connectors Between Reinforced Concrete Manhole Structures, Pipes, and Laterals, indicates a product-focused specification for connector assemblies used at critical joints in concrete manhole systems. ASTM C923/C923M sets a technical framework that manufacturers and buyers can use to evaluate connector design and intended performance in service. As a specification, it is commonly referenced when consistency, compatibility, and dependable connection behavior are important in sewer and drainage infrastructure.

Common use cases of ASTM C923/C923M

This standard is commonly used when specifying connectors that join reinforced concrete manhole structures to pipes and laterals in underground utility installations. It is relevant during project design, submittal review, and procurement when resilient connection performance must be addressed in a clear, standardized way. ASTM C923/C923M is especially useful for teams working with manholes, pipe penetrations, and lateral tie-ins where the connector is an important interface between concrete structures and adjoining piping components.

Benefits of using ASTM C923/C923M

Using ASTM C923/C923M helps create a common reference for product selection, compliance review, and quality control. It supports more consistent purchasing decisions by defining expectations around resilient connectors for manhole, pipe, and lateral connections. In practice, that can reduce ambiguity during specification writing, testing, and inspection, while also helping limit risk tied to mismatched components or unclear product claims. ASTM C923/C923M provides a practical technical benchmark for evaluating connector suitability.
