ASTM D7349/D7349M-15(2019)

Standard Test Method for Determining the Capability of Roofing and Waterproofing Materials to Seal Around Fasteners

SIGNIFICANCE AND USE
5.1 In some situations, penetration through asphalt-based roofing or waterproofing materials by fasteners is a required part of the material installation process or occurs during installation of other system components. When fasteners penetrate the material as a purposeful and planned part of the construction process, it is reasonable to expect that materials designed to limit migration of liquid water at the interface between the penetrating fastener and the material will do so. This qualitative test method provides a means to evaluate the ability of a material to limit water migration at fastener penetrations when tested under defined conditions.
SCOPE
1.1 This qualitative test method determines the capability of asphalt-based roofing or waterproofing material to seal around a fastener that penetrates the material and prevent transmission of liquid water through the material at the penetration under defined conditions.  
1.2 This test method is provided for adoption by ASTM or other consensus-based roofing and waterproofing product specifications as a standardized means to evaluate capability to seal around a fastener. Performance of this test method after subjecting the product to conditioning intended to simulate environmental stresses and strains is not prohibited.  
1.3 The text of this test method references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.  
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview

ASTM D7349/D7349M-15(2019) is the standard test method developed by ASTM International for determining the capability of asphalt-based roofing and waterproofing materials to seal around fasteners. This standard provides a qualitative procedure to evaluate how well roofing or waterproofing membranes resist liquid water intrusion at fastener penetrations under controlled test conditions. Ensuring effective water sealing at these critical points is essential in building envelope protection to prevent leaks and subsequent damage.

Key Topics

• Purpose: The method provides a standardized means of evaluating the water seal integrity of roofing and waterproofing materials when penetrated by fasteners-a common occurrence during installation.
• Application conditions: Evaluates material performance after proper conditioning to reflect environmental stresses that may occur during actual use.
• Test protocols: Multiple protocols are included to address a variety of roofing systems, substrates, fastener types, and application methods, reflecting real-world scenarios such as steep-slope roofing underlayment used for ice dam protection.
• Pass criteria: Materials pass the test if no water migrates to the underside of the substrate, the shank of the fastener, or inside the supporting can during the test duration.
• Reporting: Requires comprehensive reporting of test conditions, materials, number of specimens, and outcomes for reliable comparison and product improvement.

Applications

ASTM D7349/D7349M-15(2019) is widely applied in the roofing and waterproofing products industry to:

• Product development and quality assurance: Manufacturers use this test to verify and optimize the water-sealing capabilities of asphalt-based membranes and related products, ensuring compliance with performance specifications.
• Specification compliance: Architects, builders, and product specifiers reference this standard to ensure that selected roofing and waterproofing products can reliably prevent water intrusion around fastener penetrations.
• Certification and market acceptance: Products tested to ASTM D7349/D7349M-15(2019) are more readily accepted in the marketplace, providing assurance to contractors and building owners regarding long-term water resistance.
• Standardization: The method serves as a consensus-based approach for evaluating a critical aspect of membrane roofing systems, supporting regulatory and code-compliance requirements worldwide.

Related Standards

For comprehensive evaluation and specification of roofing and waterproofing materials, consider these related ASTM standards:

• ASTM D1079: Terminology Relating to Roofing and Waterproofing
• ASTM D3462/D3462M: Specification for Asphalt Shingles Made from Glass Felt and Surfaced with Mineral Granules
• ASTM D5147/D5147M: Test Methods for Sampling and Testing Modified Bituminous Sheet Material
• ASTM F1667: Specification for Driven Fasteners: Nails, Spikes, and Staples

Practical Value

By adopting ASTM D7349/D7349M-15(2019) in material testing and product selection processes, stakeholders in the construction and roofing industries can ensure:

• Enhanced protection against water infiltration at fastener points
• Improved durability and lifespan of roofing and waterproofing systems
• Greater confidence in meeting building codes and warranty requirements
• A level playing field for product comparison through standardized protocols
