Comprehensive Guide to ASTM E112 Determination of Average Grain Size Laboratory Testing Service Provided by Eurolab
Standard-Related Information
ASTM E112 is a widely recognized standard for determining the average grain size of metals. This standard, published by the American Society for Testing and Materials (ASTM), provides a method for measuring the average grain size of various metals using optical or electron microscopy.
The standard is based on the principles of metallography, which involves the examination of the internal structure of metals. The average grain size is an important parameter in determining the mechanical properties of metals, such as strength, toughness, and ductility.
International and National Standards
ASTM E112 is a national standard that has been adopted by many countries worldwide. Some of the international standards related to ASTM E112 include:
National standards, such as DIN 50135-2:2009 (Germany) and JIS G3200:2015 (Japan), also reference ASTM E112.
Standard Development Organizations
The development of standards is a collaborative effort between various organizations, including:
These organizations work together to develop and maintain international and national standards for metallic materials.
Evolution and Updates
Standards evolve over time as new technologies and research findings become available. ASTM E112 has undergone several revisions since its initial publication in 1957. The most recent revision, published in 2019, includes updates to the testing methodology and measurement procedures.
