Coastal and Floodplain Construction Inspector's Practice Exam

Which ASTM standard do round timber poles need to comply with?

1. ASTM D 25

2. ASTM D 3200

3. ASTM D 198

4. ASTM D 7032

The correct answer is: ASTM D 3200

Round timber poles are primarily governed by ASTM D 7032, which outlines the specifications for solid sawn and round timber poles for various applications, including utility and structural purposes. This standard ensures that timber poles have the necessary mechanical properties, durability, and treatment requirements to withstand environmental conditions, particularly in coastal and floodplain areas where exposure to moisture and potential flooding can occur. The ASTM D 7032 standard includes guidance on the grading of timber, acceptable defects, and the treatment processes that enhance the longevity of the poles in specific service conditions. This compliance helps inspectors ensure that the timber used in construction is suitable for its intended use and meets safety and performance expectations. The other standards mentioned relate to different aspects or types of wood products. ASTM D 25 focuses on the specific characteristics of round timber, but it does not fully encompass the intended applications and requirements for round timber poles like ASTM D 7032 does. ASTM D 3200 pertains to composite wood products, and ASTM D 198 deals with the testing of structural glued-laminated timber. These standards are relevant to their own contexts but do not apply specifically to the compliance requirements for round timber poles.
