DIN EN 13880-10-2003 specifies the test method for the measurement of expansion rate and adhesion of hot sealants under continuous expansion and compression conditions. This standard aims to evaluate the expansion performance of hot sealants in practical applications and their adhesion to substrates, especially under expansion and pressure caused by temperature changes. Through testing, the durability and Reliability of hot sealants in roads, bridges, building joints, etc. are ensured, and their stable performance in long-term use is guaranteed. This standard provides a scientific basis for the selection, production, quality control and engineering applications of hot sealants, helping to improve their application effect and safety.
