What is the most common SDO in the construction industry?

In the construction industry, ASTM (American Society for Testing and Materials) is recognized as the most common SDO (Standards Developing Organization). ASTM plays a crucial role in the development and delivery of voluntary consensus standards for materials, products, systems, and services used in construction and many other industries. These standards ensure quality, safety, and reliability, which are vital components in construction practices.

ASTM standards are widely adopted and referenced within contract documents and codes, making them integral to construction specifications and project execution. The organization's extensive catalog covers a wide range of materials and practices, facilitating consistency and promoting innovation across the sector.

While ISO (International Organization for Standardization), ANSI (American National Standards Institute), and UL (Underwriters Laboratories) also contribute to standards in construction, ASTM's scope, frequency of use, and specific focus on materials and testing in the construction industry solidify its position as the most common SDO.
