Overview
ASTM E 738 is a standardized analytical test procedure for determining aluminum concentration in iron ores by EDTA complexometric titration, using well-defined dissolution and separation methods to ensure reliable results. The test procedure for determining aluminum concentration in iron ores by EDTA titration is specified in ASTM E 738, which provides detailed information on specimen preparation, reagents, and titration methods to obtain accurate aluminum concentration results for iron ore samples.
Scope, Applications, and Benefits
Scope
The ASTM E 738 test method is used to determine the aluminum content in iron ore samples by dissolving the matrix, separating interfering elements, and titrating the aluminum content with a known amount of EDTA solution at specific pH and indicator conditions, which helps to determine the accurate amount of aluminum content in different types of iron ores and concentration ranges in mining and processing programs.
ASTM E 738 aluminum determination testing evaluates:
- Aluminum concentration in iron ore, sinter feed, and pellet feed material samples
- EDTA complexometric titrimetric aluminum measurement in iron ore sample matrices
- Comparative aluminum content across iron ore types, sources, and processing streams
- Effect of sample preparation, dissolution procedure, and matrix separation on aluminum accuracy
- Compliance with defined aluminum content requirements for iron ore specifications
Applications
- Iron ore mining and processing operations require aluminum content characterization
- Sinter plant and blast furnace operations require iron ore and aluminum content data
- Iron ore trading and commercial transactions, aluminum content verification programs
- Steel plant raw material incoming inspection and ore blend aluminum assessment
- Mining laboratories and ore processors requiring ASTM E 738 aluminum test data
Benefits
- Provides reliable aluminum content data for iron ore characterization and process control
- Supports iron ore specification compliance and supplier assessment programs
- Identifies elevated aluminum content in iron ore before processing operations
- Delivers traceable aluminum concentration test records for commercial and engineering submissions
- Reduces process risk by verifying iron ore and aluminum content early in the ore assessment cycle

Frequently Asked Questions
ASTM E69 tests the flammable properties of treated wood using a fire-tube device. This test helps show how chemical treatments affect ignition patterns, flame growth, and combustion reactions under controlled lab fire conditions.
ASTM E69 compares the fire performance of treated wood materials. It shows if preservative or fire-retardant treatments change combustibility. This helps in choosing safer materials for building, industrial, utility, and specialty wood uses.
ASTM E69 is often used for chemically treated lumber, preserved wood products, and fire-retardant-treated wood. It applies in construction, utilities, transportation, and industrial settings where it is important to assess combustible behavior carefully.
ASTM E69 testing puts treated wood samples in a fire-tube device under controlled conditions. It observes ignition, flame behavior, and combustion traits to evaluate the flammable properties of the material being tested.
ASTM E69 tests how materials burn in a lab setting. It may not capture real-life fire situations. Factors like ventilation, product shape, installation methods, and how materials interact with each other can influence performance.
