YBB00212003 Test Method and Significance for Linear Thermal Expansion Coefficient of Medicinal Glass Containers

　　1、 Purpose and significance of the experiment

The coefficient of thermal expansion is one of the important indicators for evaluating the physical properties of medicinal glass containers, which directly affects the thermal stability and sealing of the container. Due to temperature changes that drugs may undergo during filling, sterilization, storage, and other processes, if the thermal expansion coefficient of the glass container does not match the drug or sealing material, it may cause deformation, sealing failure, or even rupture of the container, thereby affecting drug safety. According to the YBB00212003-2015 standard, by measuring the coefficient of thermal expansion, it is possible to verify whether the glass material meets the temperature resistance requirements of pharmaceutical packaging, ensuring its reliability in practical applications.
