Which organization is responsible for establishing the procedures for penetration test boring?

The American Society for Testing and Materials (ASTM) is the organization that establishes standards and procedures for a variety of materials testing, including penetration testing for soils. ASTM has developed specific standards that detail the methods for conducting penetration tests, which are essential for determining the properties of soil and assessing subsurface conditions prior to construction. These standards ensure consistency, reliability, and safety in the testing process, providing guidelines that engineers and contractors follow during site investigations.

This reinforces the importance of standardized testing procedures in construction and engineering projects, ensuring that soil properties are verified under controlled conditions. The other organizations listed focus on different aspects of civil engineering, infrastructure, or broader standards, but ASTM is specifically recognized for its role in developing and maintaining standards related to testing materials.
