About This Item
ASTM D8063 is the ASTM standard for determining water in purified terephthalic acid (PTA) by volumetric Karl Fischer titration. It provides a controlled test approach for measuring moisture content in PTA, a detail that can affect material quality, handling, and downstream processing. By defining a specific analytical method, ASTM D8063 supports more consistent testing and clearer comparison of results across laboratories and production settings.
ASTM D8063 standard overview
This standard focuses on water determination in purified terephthalic acid using volumetric Karl Fischer titration, a widely recognized analytical technique for moisture measurement. The document is relevant to users who need a dependable laboratory method for assessing PTA samples with consistency and repeatability in mind. ASTM D8063 helps align testing practices around a shared technical procedure, making it easier to support quality control, specification checks, and product evaluation with a common reference method.
Where is ASTM D8063 used?
ASTM D8063 is typically used in laboratories and quality control environments that test purified terephthalic acid. It is most relevant where PTA must be checked for water content before use, storage, or transfer in manufacturing and material qualification workflows. The standard is commonly applied by analysts, suppliers, and buyers who need a recognized test method for comparing results and confirming that the material meets internal or contractual requirements.
Practical importance of ASTM D8063
In practice, ASTM D8063 supports more reliable moisture testing for PTA by giving organizations a standardized way to measure water content. That can help reduce variation between test results, improve procurement decisions, and strengthen product acceptance or release procedures. For facilities that depend on consistent raw material quality, the method can also aid risk reduction by making analytical results easier to document, review, and defend during routine quality control or compliance checks.
