Coastal and Floodplain Construction Inspector's Practice Exam

Piles must comply with which ASTM standard?

1. ASTM D 25

2. ASTM D 3200

3. ASTM D 1970

4. ASTM A 500

The correct answer is: ASTM D 25

Piles used in construction must comply with ASTM D 25, which outlines the standard practices for the testing and quality control of timber piles. This standard provides essential guidelines for the properties of wood and certain design considerations, ensuring that timber used in pile construction is suitable for the intended load-bearing applications. Compliance with this standard is crucial to ensure the structural integrity and performance of the piles under various environmental conditions, particularly in coastal and floodplain areas where exposure to moisture and potential decay can affect longevity and strength. The other standards listed pertain to different materials and applications. ASTM D 3200 relates to the specifications for internal and external sealants, ASTM D 1970 pertains to the standards for self-adhering polymer modified bitumen sheet materials for roofing, and ASTM A 500 provides specifications specific to cold-formed welded and seamless carbon steel structural tubing. While all these standards are important in their respective contexts, none directly address the requirements for pile materials as ASTM D 25 does.
