About This Item
ASTM D2868 is the ASTM standard that addresses nitrogen content by the Kjeldahl method and hide substance content in leather, wet blue, and wet white. It is used to support consistent testing of these materials when chemical composition needs to be measured for quality control, product evaluation, or compliance purposes. By defining a recognized test method, ASTM D2868 helps make results more comparable across laboratories and supply chains.
What is ASTM D2868?
This standard provides a technical test method for determining nitrogen content using the Kjeldahl approach, along with hide substance content, in leather and related intermediate materials. Its purpose is to give buyers, manufacturers, and testing laboratories a common reference for measuring these properties in a repeatable way. ASTM D2868 is especially relevant when a material’s chemical characteristics need to be checked against product requirements, specifications, or internal quality procedures.
Where is ASTM D2868 used?
ASTM D2868 is commonly used in laboratories and quality control settings that test leather, wet blue, and wet white. These materials are often evaluated during production, incoming inspection, or final product verification. The standard is useful wherever a controlled method is needed to assess nitrogen content or hide substance content as part of material characterization. It may also support documentation for procurement and supplier verification in leather-related workflows.
Why is ASTM D2868 important?
ASTM D2868 matters because it helps create consistency in testing results for materials that can vary in composition and processing history. A recognized test method supports clearer communication between suppliers, laboratories, and purchasers, reducing uncertainty when specifications must be met. In practice, this can improve confidence in quality control decisions, comparison of test data, and acceptance of leather-related materials. ASTM D2868 also helps reduce risk by aligning testing with an established standard.
