DIN EN 12614 PDF Download

The DIN EN 12614 standard focuses on test methods for determining the glass transition temperatures (GTT) of polymers. The glass transition temperature is an important property of polymers, as it indicates their susceptibility to deformation or damage under different temperature conditions. The standard outlines the use of differential scanning calorimetry (DSC) or differential thermal analysis (DTA) as the preferred methods for conducting this test.

DSC and DTA are analytical techniques that measure the heat flow or temperature difference between a sample and a reference material as a function of temperature. By subjecting the polymers to controlled heating or cooling cycles, the transition from the glassy state to the rubbery state can be observed and the corresponding glass transition temperature can be determined. This information is essential for assessing the thermal behavior and performance of polymers used in products and systems for the protection and repair of concrete structures.

By providing a standardized test method, the DIN EN 12614 standard ensures that consistent and reliable measurements of glass transition temperatures can be obtained across different laboratories and testing facilities. This allows manufacturers, researchers, and regulators to compare and evaluate the performance of polymer materials under different temperature conditions, and make informed decisions regarding their suitability for concrete protection and repair applications.
