Full title and description
Standard Specification for Resilient Connectors Between Reinforced Concrete On‑Site Wastewater Tanks and Pipes — ASTM C1644/C1644M-24. This specification establishes minimum material and performance requirements and required test procedures for resilient connectors used to join reinforced concrete on‑site wastewater (septic) tanks to piping systems to prevent leakage and accommodate movement.
Abstract
This specification covers material, design, and performance requirements for resilient connectors used at connections between reinforced concrete on‑site wastewater tanks and pipes. All materials are required to be suitable for sanitary sewage service. Each connector design must be tested for straight alignment, axial deflection, and shear loading, and meet specified acceptance criteria. Test provisions address hydrostatic performance up to 5 psi (11.5 ft) and both SI and inch‑pound unit systems are permitted independently.

Scope
The standard specifies minimum performance and material requirements for resilient connectors intended for connections between reinforced concrete on‑site wastewater tanks and pipes (including connectors used with structures covered by Specifications C913 and C1227). The scope is limited to the resilient connection itself and its performance under straight alignment, axial deflection, and shear loading tests; it does not address all factors affecting installed system infiltration/exfiltration beyond the connector. The specification permits use of either SI or inch‑pound units (treated independently).
Key topics and requirements
- Material suitability for sanitary sewage service (chemical and environmental resistance).
- Minimum performance criteria for leakage and mechanical behaviour.
- Required test methods: straight alignment, axial deflection, and shear loading.
- Hydrostatic performance provisions (tested for leakage at pressures up to 5 psi / ~11.5 ft head).
- Design, marking, and product acceptance criteria for connector types.
- Separate, non‑interchangeable use of SI and inch‑pound units to avoid non‑conformance.
Typical use and users
Used by manufacturers of resilient connectors and seals, precast concrete septic tank and grease interceptor producers, civil and wastewater engineers, product testing laboratories, specification writers, and regulatory bodies overseeing on‑site wastewater systems. Typical applications include sealing inlet/outlet pipe penetrations in reinforced concrete septic tanks and other on‑site wastewater structures to prevent leakage while accommodating movement.
Related standards
Referenced and related standards include ASTM C913 (Precast Concrete Water and Wastewater Structures), ASTM C1227 (Precast Concrete Septic Tanks), and several elastomer/material test methods and specifications that address chemical resistance and rubber properties (for example ASTM test methods referenced within the specification). Additional related ASTM standards on joint materials and seal testing are commonly used in conjunction with C1644/C1644M.
