DIN EN 13880-12-2003 《Hot applied joint sealants - Test methods - Part 12: Manufacture of concrete test blocks for bond testing (recipe methods)》 Related products

DIN EN 13880-12-2003 specifies the preparation method for concrete specimens used to determine the swelling rate and adhesion of hot sealants. The standard describes in detail the design, preparation and handling requirements of the specimens to ensure uniform mass and performance of concrete specimens during testing. By specifying the preparation method of the specimen, the standard provides a reliable basis for subsequent evaluation of the performance of hot sealants under expansion conditions and adhesion to substrates. This method is suitable for thermal sealants used in roads, bridges and construction joints, helping to ensure the durability and adhesion performance of materials in actual use, providing technical support for Product Research & Development and quality control.
