The American Society for Testing and Materials (ASTM) has set forth performance standards for commercial outdoor furniture. Commercial furniture is designed to be easily maintained and handle frequent and consistent usage.
ASTM International, founded as the American Society for Testing and Materials, is a nonprofit organization that develops and publishes approximately 12,000 technical standards, covering the procedures for testing and classification of materials of every sort. Headquartered in West Conshohocken, United States, ASTM standards are used worldwide, with its membership consisting of over 30,000 members representing 135 countries. ASTM also serves as the administrator for the U.S. TAGs (United States Technical Advisory Group) to an enormous amount of ISO/TCs (International Organization for Standardization/Technical Committee) and to their subcommittees.
