Tensile strength is a critical criterion in evaluating the durability, elasticity, and general performance of foam materials. This test clearly reveals the quality level of the material by measuring both its resistance to mechanical loads and its stretching capacity. The test sample is specially cut in a dumbbell shape and fixed to the grips of the tensile strength machine. The foam is stretched at a controlled speed until the breaking point, and important data about the structural durability of the foam is obtained during this process. The machine calculates the maximum force required for the foam sample to break and specifies the tensile strength in N/mm². Additionally, how much the foam stretches at the moment of break is measured as a percentage (%), and this value gives information about the stretching capability of the foam. All measurements obtained are carried out according to the TS 2012 EN ISO 1798 standard to ensure international compliance and reliability.
