Asphalt shingles not included in ASTM D7158 must be tested to indicate compliance with which standard?

• A. ASTM D3161
• B. ASTM D7322
• C. ASTM D4218
• D. ASTM D7864

Answer: (A)

Asphalt shingles that do not meet the criteria set forth in ASTM D7158 are required to adhere to ASTM D3161. This standard focuses on the wind resistance of asphalt shingles specifically, by utilizing a dynamic test method to evaluate their performance under wind uplift conditions. It establishes a rating system that helps ensure these shingles can withstand certain levels of wind, making it a critical benchmark for roofing products designed for areas prone to high winds. In contrast, the other standards mentioned either pertain to different aspects of roofing materials or are focused on materials that do not directly relate to the wind resistance testing needed for shingles that fall outside the scope of ASTM D7158. Understanding the specific focus of each standard clarifies the necessity of ASTM D3161 for assuring the durability and reliability of asphalt roofing under wind stress.
