About This Item
ASTM D5349 is the standard test method for determining the moisture and volatile content of sulfonated, sulfated oils and fatliquors by oven method. It provides a practical approach for measuring how much water and other volatile components are present in these materials, which can affect handling, consistency, and quality control. For users working with tanning and related processing inputs, this ASTM standard supports more reliable testing and product evaluation.
Purpose of ASTM D5349
The purpose of ASTM D5349 is to define an oven-based test method for determining moisture and volatile content in sulfonated, sulfated oils and fatliquors. This helps laboratories and manufacturers use a consistent procedure when checking material composition. By focusing on loss of moisture and other volatiles under controlled heating, the standard supports repeatable results and clearer comparisons between lots, suppliers, or production batches.
Common use cases of ASTM D5349
This standard is commonly used in quality control and incoming inspection for sulfonated, sulfated oils, and fatliquors. It may be applied when evaluating raw materials, monitoring production consistency, or confirming that a product meets internal specifications before use. Because the test is based on oven drying, it is also relevant in laboratory workflows that require a straightforward method for assessing moisture and volatile content in these specialty materials.
Why ASTM D5349 matters
ASTM D5349 matters because moisture and volatile content can influence material stability, storage behavior, and end-use performance. A standardized test method helps reduce uncertainty when comparing results across facilities or over time. It also supports procurement decisions, specification checks, and routine quality control by giving buyers and producers a common basis for assessment. Using a recognized ASTM standard can help improve confidence in testing outcomes and reduce the risk of inconsistent material acceptance.
