It is a requirement under the standard size foam sample to the provisions of the sag, measured compressive strength foam trap generated power, the ability to use Newton said it related to the performance and materials, and equipment the force imposed on the sample size of equal and opposite, record the force value, the indentation hardness can be measured.

The KR‑713 bench‑top foam indentation hardness and dynamic fatigue tester is purpose‑built for mechanical‑property assessment of flexible porous polymer foam and sponge materials. Following GB10807‑89 specification for soft foamed polymeric materials, this instrument measures indentation force, indentation hardness, compression resistance, and dynamic fatigue degradation after repeated cyclic compression.
When a standard‑dimension foam specimen is placed under the circular pressure head, the equipment applies controlled vertical compression load, records real‑time reaction force exerted by the sample, and calculates indentation‑hardness indexes via built‑in algorithms. It supports three official indentation‑hardness test modes, widely deployed by furniture‑foam factories, automotive‑seat‑component manufacturers, polymer‑material R&D labs and third‑party material‑quality‑verification institutes.
