About This Item
ASTM E342 is the ASTM standard for the Standard Test Method for Determination of Chromium Oxide in Chrome Ores by Permanganate Titrimetry. It provides a recognized approach for measuring chromium oxide content in chrome ore samples, helping laboratories and buyers rely on a consistent analytical method. By defining a clear test procedure, ASTM E342 supports more dependable reporting, comparison, and quality decisions when chromium oxide results are part of material evaluation.
Purpose of ASTM E342
The purpose of ASTM E342 is to describe a test method for determining chromium oxide in chrome ores using permanganate titrimetry. This gives laboratories a standardized way to analyze ore composition and report results with greater consistency. The method is especially useful where chromium oxide content needs to be measured for acceptance, specification checks, or process control. As an ASTM standard, it helps align testing practices around a common technical reference.
Common use cases of ASTM E342
ASTM E342 is commonly used in laboratory settings that evaluate chrome ore samples for chromium oxide content. It may support ore purchasing, inspection, incoming material verification, and routine quality control where analytical consistency matters. The standard is also relevant when comparing test results between laboratories or maintaining a documented method for mineral analysis. In practice, it serves users who need a reliable titrimetric procedure for chrome ore testing.
Why ASTM E342 matters
This standard matters because test results for chromium oxide can influence material acceptance, reporting, and downstream decisions. ASTM E342 helps reduce variation by defining a specific analytical method, which supports more repeatable and defensible results. For organizations involved in chrome ore testing, using a recognized standard can improve confidence in laboratory output, strengthen procurement and quality workflows, and lower the risk of inconsistent measurements affecting business decisions.
