ISO 11527:2010 PDF Download

ISO 11527:2010 is a standard that provides a test method for evaluating the stringiness of wet-applied sealants used in building construction. The stringiness of a sealant refers to its ability to form and maintain a continuous and stable thread or string when applied. The standard outlines a specific procedure to assess this characteristic.

The method described in ISO 11527:2010 involves applying the sealant to a vertical surface in a controlled manner and observing its behavior. The sealant is allowed to flow downward under gravity, and its ability to form a continuous thread is evaluated. Factors such as the length and stability of the thread, as well as any sagging, are taken into account during the assessment.

By providing a standardized procedure, ISO 11527:2010 ensures consistency in evaluating the stringiness of sealants. This allows manufacturers, contractors, and regulatory bodies to objectively assess the performance of sealants and make informed decisions regarding their use in construction projects. Ultimately, the standard helps to ensure that sealants meet the necessary requirements for forming and maintaining durable joints in buildings.
