This document introduces the "Microscopic Structure Standard Samples" handled by Yamamoto Scientific Tool Research Co., Ltd. Representative materials have been selected from the steel materials listed in JIS. These have been classified into categories from 1 to 7, and strict heat treatment has been applied to them, resulting in representative microscopic structures being produced at the Materials Technology Education Research Association. Additionally, the material properties, heat treatment conditions, and structures are thoroughly explained through actual standard samples, their photographs, and detailed descriptions to ensure a comprehensive understanding.

This product is a spark test standard specimen for understanding the characteristics of machine materials. It complies with JIS G0566-1980 and is specifically selected for educational training and general factory use, focusing on commonly used JIS steel materials. It is organized into three series: Group F, G, and H, which have been professionally selected from the K group and various steel type groups, and has undergone rigorous chemical analysis. The judgment becomes easier, quicker, and more reliable, and the results are based on a higher level of objectivity rather than solely relying on the observer's subjectivity. 【Features】 ■ The judgment is not influenced by the shape, roughness, or heat treatment structure of the sample. ■ Non-destructive full inspection is possible (excluding finished products). ■ Low equipment costs, time, and effort required. *For more details, please refer to the PDF document or feel free to contact us.

The high-precision "hardness reference specimen" has been nurtured in Japan and is recognized worldwide for its hardness uniformity and standard values based on international standards. It is a standard test piece compliant with ISO and JIS for indirect verification of hardness testers, widely used around the globe. Various certifications, such as the ISO 9000 series, require management of testing machines in accordance with ISO and JIS standards. We encourage daily management to confirm the accuracy, stability, and reproducibility of testing machines, and we are currently actively developing reference specimens for nanoindentation under guidance from various sectors. 【Features】 ○ Excellent hardness uniformity ○ No time-dependent changes in hardness ○ Compliant with Japanese Industrial Standards → Registration Certificate Number JQA-2078 ISO 9001-2000 / JIS Q 9001:2000 For more details, please contact us or download the catalog.
