Symposium 50 Years of Characterizing Structural Ceramics and Glasses: Recognizing the Contributions of George Quinn
Presentation Title On the Controversies during the Creation of Flexure Strength Standards MIL STD 1942 and ASTM C 1161
Author(s) George D. Quinn
On-Site Speaker (Planned) George D. Quinn
Abstract Scope Flexural strength test standards MIL STD 1942 and ASTM C 1161 were created in the 1980s by the author while at the U.S. Army Materials Technology Laboratory in Watertown, Massachusetts. They revolutionized how the flexural strength of structural ceramics is measured. The U. S. Army Military Standard MIL STD 1942 came first in 1983. It was my first Standard and was created from scratch, unlike many standards that are clones of earlier documents. The MIL STD had as its foundation a comprehensive error analysis created by Frank Baratta. I corrected some of his analyses and used my own materials science, fractographic, and statistics know-how to craft the MIL STD. It was very controversial at the time and there were dramatic incidents and confrontations along the way. I recount a few of these that helped prepare me for the twenty-four standards that I created or coauthored over the years.
