Which organization is responsible for standardizing symbols used to indicate materials of construction in a sketch?

The American Standards Association (ASA) played a pivotal role in developing standards for symbols and terminology in various engineering fields, including the standardization of symbols used to indicate materials of construction in sketches. The organization aimed to improve consistency and clarity in technical communication, ensuring that engineers and designers could effectively understand and interpret engineering documents. Although the ASA has since evolved and merged into other organizations, its historical significance in standardizing technical symbols remains noteworthy.

While ANSI is currently responsible for overseeing the development of standards in the U.S. and often sets guidelines similar to those initially established by ASA, the question specifically asks for the organization historically recognized for this particular task. ISO sets international standards and ASME focuses on mechanical engineering and design standards, but they do not have the same historical context that ASA has regarding the standardization of symbols in engineering sketches.
