Building Construction - Jointing Products - Determination of Adhesion/Cohesion Properties of Sealants at Variable Temperatures
Also Known As:
The DIN EN ISO 9047 standard provides a method for evaluating the adhesion and cohesion properties of sealants used in building constructions. This standard specifically focuses on sealants with predominantly elastic behavior.
The standard outlines a procedure where the sealant is applied to two parallel contact surfaces on test specimens. These specimens are then subjected to extension and compression cycles under defined conditions. The purpose of these cycles is to simulate the various environmental conditions that the sealant may be exposed to during its service life.
During these cycles, any breaks in the adhesion or cohesion of the sealant are documented. This allows for an assessment of how well the sealant maintains its stability and performance under variable temperature conditions.
By providing a standardized method for evaluating sealant properties, the DIN EN ISO 9047 standard ensures that the sealant used in building construction meets the required quality and performance standards, providing confidence in its ability to effectively seal joints and withstand temperature variations.
