About This Item
ASTM D6980 is a technical standard for determining moisture in plastics by loss in weight, helping users measure how much water content is present in a material sample. This matters because moisture can affect processing, product consistency, and test results in plastic materials. As an ASTM standard, it provides a structured approach for comparing measurements and supporting quality control, specification checks, and routine materials evaluation.
What is ASTM D6980?
ASTM D6980, titled Standard Test Method for Determination of Moisture in Plastics by Loss in Weight, describes a method for evaluating moisture content in plastics based on weight change. In practical terms, the standard supports a controlled test approach that can be used to estimate how much moisture is present before or after processing. It is typically used as a technical reference when a consistent, repeatable method is needed for plastics moisture determination.
Where is ASTM D6980 used?
This standard is commonly used in plastics testing and quality control environments where moisture levels need to be checked for incoming materials, in-process samples, or finished products. It may be applied in laboratories and manufacturing workflows that handle plastic resins, pellets, molded parts, or other plastic forms. ASTM D6980 is especially useful when a loss-in-weight method is preferred for routine assessment and documentation of moisture-related conditions.
Why is ASTM D6980 important?
ASTM D6980 helps support reliable moisture measurement, which can be important for material handling, process stability, and product evaluation. Consistent testing can reduce variation between samples and improve confidence in procurement and compliance decisions. For organizations working with plastics, the standard offers a clear technical basis for routine checks, helping reduce the risk of moisture-related performance issues and supporting better quality control practices.
