ASTM D4932/D4932M-89 (R2019) PDF Download

The ASTM D4932/D4932M-89 (R2019) standard provides guidelines for testing the resistance of roofing and waterproofing materials to fastener pull-through. The standard helps determine appropriate fastener spacing and evaluates the performance of different types of fasteners, including those with and without caps.

The standard emphasizes that laboratory test data cannot accurately predict long-term performance in the field. It also highlights the importance of ensuring that all test conditions are uniform to ensure comparability of data.

The test method described in the standard involves measuring the force required to pull a fastener through various types of roofing or waterproofing materials, such as ply sheets, roll roofing, or shingles, under controlled laboratory conditions. The purpose is to assess the material's resistance to fastener pull-through and the potential for fastener failure.
