When fasteners penetrate roofing or waterproofing products as a planned part of installation, it is expected in some cases that the product will resist water migration at the point of penetration. A new ASTM International standard, D7349 , Test Method for Determining the Capability of Roofing and Waterproofing Materials to Seal Around Fasteners, addresses this situation. ASTM D7349 was developed…
