About This Item
ASTM E247 is a test method for determining silica in manganese ores, iron ores, and related materials by gravimetry. It is used to support reliable laboratory analysis where silica content must be measured with consistency and care. By focusing on a defined analytical procedure, this ASTM standard helps laboratories and buyers evaluate material quality, compare results more effectively, and support technical decisions tied to ore composition and process control.
What is ASTM E247?
ASTM E247, Standard Test Method for Determination of Silica in Manganese Ores, Iron Ores, and Related Materials by Gravimetry, provides a structured approach for measuring silica content in selected ore materials. The standard is centered on gravimetric analysis, a classical laboratory technique used to determine the amount of a substance by measurement of mass. In practical terms, it gives a clear technical reference for laboratories that need a consistent method for silica determination.
Where is ASTM E247 used?
This standard is commonly used in laboratories that test manganese ores, iron ores, and similar mineral materials. It is relevant wherever silica content must be checked for material evaluation, acceptance testing, or quality control. ASTM E247 may also support procurement and supplier verification when silica levels are an important part of the material specification or reporting workflow. Its value is highest in settings that rely on repeatable analytical results.
Why is ASTM E247 important?
ASTM E247 matters because silica content can influence how ores are assessed, processed, and compared against technical requirements. A defined test method helps reduce variation between laboratories and supports more dependable reporting. For organizations involved in testing, purchasing, or quality review, the standard can improve consistency and lower the risk of misunderstandings about material composition. It also provides a recognized basis for compliance and documentation.
