About This Item
ASTM D513 is the ASTM standard for Standard Test Methods for Total and Dissolved Carbon Dioxide in Water. It provides a technical basis for measuring carbon dioxide content in water, helping users evaluate water quality with greater consistency. Because total and dissolved carbon dioxide can affect treatment decisions, process control, and analytical reporting, this standard is useful for labs and facilities that need reliable, comparable test results for water samples.
Purpose of ASTM D513
The purpose of ASTM D513 is to define test methods for determining carbon dioxide in water in a controlled and repeatable way. The standard supports measurement of both total and dissolved carbon dioxide, which may be important when water chemistry needs to be documented or compared across samples. By providing a recognized ASTM standard, it helps reduce variation in testing practices and supports more dependable results for routine analysis, monitoring, and quality assessment.
Common use cases of ASTM D513
This standard is commonly used in water testing workflows where carbon dioxide levels need to be measured for reporting or control purposes. It may be applied in laboratory analysis of drinking water, process water, industrial water, or other water samples where dissolved gases influence performance or chemistry. ASTM D513 is also relevant when selecting test methods for compliance work, incoming water evaluation, or general quality control in water-focused operations.
Why ASTM D513 matters
ASTM D513 matters because carbon dioxide measurements can affect how water is interpreted and managed. Using a recognized test method supports consistency across laboratories, better procurement decisions, and more dependable quality control. It can also help reduce uncertainty when comparing results over time or between locations. For organizations that depend on accurate water analysis, this ASTM standard offers a practical reference for standardized testing and documentation.
