ASTM C985M is the ASTM standard that covers nonreinforced concrete culvert, storm drain, and sewer pipe specified by metric requirements. It is relevant for buyers, engineers, and specifiers who need a clear technical basis for evaluating pipe products used in underground drainage and conveyance applications. By defining a consistent specification for this pipe type, it helps support product selection, procurement, and quality control for infrastructure projects where reliable performance matters.

What is ASTM C985M?

ASTM C985M is a product specification for nonreinforced concrete pipe made for culvert, storm drain, and sewer service in metric dimensions. As an ASTM standard, it establishes the requirements that pipe products are typically expected to meet for this application category. The standard is useful when comparing manufactured pipe options, reviewing compliance documents, or aligning purchasing specifications with project needs. ASTM C985M helps provide a common technical reference for this specific concrete pipe type.

Where is ASTM C985M used?

This standard is commonly used in civil infrastructure projects involving drainage and wastewater conveyance where nonreinforced concrete pipe may be specified. It is relevant for culverts, storm drainage systems, and sewer installations that rely on metric sizing. Contractors, engineers, manufacturers, and procurement teams may use ASTM C985M during specification writing, submittal review, and material acceptance. It is especially useful when consistent product identification and dimensional coordination are important across a project.

Why is ASTM C985M important?

ASTM C985M matters because it gives project teams a dependable specification framework for evaluating nonreinforced concrete pipe. That can help reduce ambiguity in procurement, support consistent product comparisons, and improve communication between design and supply teams. In practice, using a recognized ASTM standard may also help with compliance checks, quality control, and acceptance decisions. For infrastructure work, having a clear reference like ASTM C985M can lower risk and support more predictable outcomes.
