About This Item
ASTM D7967 is a technical standard for measuring chrome content, reported as Cr2O3, in wet blue using atomic absorption or ICP methods. It is intended to support consistent laboratory analysis where accurate chromium determination is needed for material evaluation and quality control. By defining a recognized test method, this ASTM standard helps improve comparability between results and supports more reliable decision-making in procurement, processing, and compliance-related workflows.
Overview of ASTM D7967
The Standard Test Method for Analysis of Chrome Content (as Cr2O3) in Wet Blue using Atomic Absorption or ICP establishes a formal approach for determining chrome content in wet blue materials. ASTM D7967 is centered on instrumental analysis, making it useful for laboratories that need a consistent, repeatable way to measure chromium levels. As a test method, it supports technical evaluation rather than product qualification on its own, and it is commonly used where analytical consistency is important.
Common use cases of ASTM D7967
This standard is commonly used in laboratory testing of wet blue during leather processing and related quality control activities. It may be applied when reviewing chrome content for production monitoring, incoming material checks, or batch comparison. Because the method uses atomic absorption or ICP, it is also relevant for labs equipped with instrumental analysis systems that handle trace or elemental measurements. ASTM D7967 helps provide a clear basis for reporting chrome content in a standardized form.
Benefits of using ASTM D7967
Using ASTM D7967 can improve consistency in chrome content testing by giving laboratories a shared method for analysis and reporting. That consistency is valuable for compliance support, product evaluation, and internal quality control. It may also reduce ambiguity in procurement or supplier communication by aligning results to a recognized ASTM standard. For organizations that rely on wet blue testing, the method helps support more dependable comparisons across batches, sites, or testing programs.
