About This Item
ASTM C1893 is the ASTM standard for laboratory performance verification of hydrodynamic separators used to treat stormwater runoff. It provides a technical basis for evaluating whether these devices perform as intended under controlled laboratory conditions. For engineers, specifiers, and product reviewers, the standard helps support more consistent comparisons of treatment performance and offers a clearer framework for assessing equipment before field use or procurement.
Purpose of ASTM C1893
The purpose of this standard is to define a laboratory practice for verifying the performance of hydrodynamic separators in stormwater treatment applications. By focusing on controlled testing, ASTM C1893 supports more consistent evaluation of how a separator responds to runoff conditions and treatment demands. It is intended to help reduce ambiguity when reviewing product performance data and to provide a common technical reference for laboratory assessment, quality control, and compliance-related decision-making.
Common use cases of ASTM C1893
This standard is commonly used when hydrodynamic separator products are being evaluated for stormwater management projects, submittals, or product qualification. It may be applied by manufacturers conducting laboratory verification, by consultants reviewing treatment device data, and by purchasers comparing equipment options. ASTM C1893 is also useful when a project requires a documented performance basis for a separator intended to treat stormwater runoff before installation or approval.
Why ASTM C1893 matters
ASTM C1893 matters because it helps create a more consistent and defensible method for verifying hydrodynamic separator performance. In practice, that can support better procurement decisions, more reliable product comparisons, and clearer communication between manufacturers and specifiers. A recognized ASTM standard also helps reduce uncertainty in testing and can improve confidence in reported results. For stormwater projects, that consistency is important when performance claims influence design, approval, or long-term quality control.
