ASTM D1607 is the ASTM standard for determining nitrogen dioxide content of the atmosphere using the Griess-Saltzman reaction. It provides a technical basis for measuring a specific air contaminant in a controlled and repeatable way, which is important for environmental monitoring, exposure assessment, and quality-related evaluations. As a recognized test method, it helps users apply a consistent approach when comparing results, documenting conditions, or supporting compliance-related decisions.

What is ASTM D1607?

ASTM D1607 is a test method focused on measuring nitrogen dioxide content in atmospheric samples through the Griess-Saltzman reaction. The official title indicates a chemical analysis approach intended for air testing, rather than a broad performance specification. In practical use, the standard supports a defined procedure for assessing NO2 in the atmosphere, helping laboratories and technical teams work from the same method when generating comparable results. ASTM D1607 is therefore a useful reference for standardized atmospheric analysis.

Where is ASTM D1607 used?

This standard is commonly used in atmospheric testing workflows where nitrogen dioxide measurement is needed. It may be applied in laboratory analysis, field-related air monitoring programs, or other technical environments that evaluate ambient air quality. Because the method centers on the atmosphere, it is most relevant to users involved in environmental measurements, compliance support, and routine air-testing programs. ASTM D1607 helps provide a common test framework for handling and reporting nitrogen dioxide data.

Why is ASTM D1607 important?

ASTM D1607 matters because standardized nitrogen dioxide testing supports consistency, traceability, and clearer decision-making. When atmospheric NO2 data are used for quality control, environmental review, or compliance-related documentation, a recognized test method reduces ambiguity in how results are obtained. It also helps users compare data across locations, projects, or laboratories with greater confidence. By defining a repeatable approach, the standard can support more reliable evaluation of atmospheric nitrogen dioxide content.
