ASTM is also known as the American Society of Testing and Materials. This international standards organization doesn’t enforce these standards, but companies can make it mandatory for employees to meet these guidelines and be compliant with ASTM standards. Materials, products, systems, and services are included in a voluntary consensus technical standards publication by ASTM. Some steel toe boots, for example, meet these standards for protecting your toes. The American Society of Testing and Materials operates globally and is based in West Conshohocken, Pennsylvania.
