ASTM D1193 is the ASTM standard that defines the specification for reagent water, a critical reference for laboratory and quality-controlled work. It provides a common basis for understanding water purity expectations when water is used in testing, preparation, or analytical procedures. By setting a consistent technical benchmark, this standard helps reduce variability and supports more reliable results across laboratories, procurement activities, and routine quality assurance programs.

ASTM D1193 standard overview

The Standard Specification for Reagent Water establishes a recognized framework for describing water intended for laboratory and technical use. As an ASTM standard, it is designed to support consistent expectations for reagent water quality rather than casual or general-purpose water. ASTM D1193 is commonly referenced when organizations need a defined basis for specifying purity, comparing supplier offerings, or aligning internal procedures with a widely used technical document.

Where is ASTM D1193 used?

This standard is commonly used in laboratories, testing environments, and other settings where water quality can affect measurements, sample preparation, or analytical outcomes. It is especially relevant in workflows that depend on controlled reagent water for consistent performance and reduced contamination risk. ASTM D1193 may also support purchasing and specification decisions when selecting water for procedures that require a clearly defined quality level.

Practical importance of ASTM D1193

In practice, ASTM D1193 helps organizations communicate and verify reagent water requirements with greater confidence. It supports compliance efforts, quality control, and procurement by giving buyers and users a common specification to reference. That can improve consistency across batches, simplify supplier evaluation, and lower the risk of using water that does not meet expected laboratory needs. For teams focused on repeatable results, the standard is a useful technical benchmark.
