This measures the maximum stress the sealant can withstand while being stretched before it breaks. In a high-rise building, wind pressure creates negative loads (suction) that try to pull the glass panels away from the frame. If the sealant’s tensile strength is insufficient, the bond fails, leading to catastrophic consequences. ISO 8339 provides the benchmark for verifying that a sealant meets the minimum strength requirements.
Sealants are chemically reactive materials (usually silicone-based). ISO 8339 mandates specific curing times and conditions (temperature and humidity) before testing can begin. This ensures the material has reached its full mechanical potential. Iso 8339 Pdf
