Mainly applicable to flexible foam polymeric materials such as sponge, foam, etc. Indentation hardness is tested under GJ standard methods A, B, and C on standard-sized sponge, foam, and other samples to measure the indentation hardness of these materials. This instrument uses computer control to quickly and accurately collect and process various data during the test, and allows storage, display, and printing. Precise curve and force value bidirectional display provides more intuitive test results. Uses precise embedded CPU control and can also directly test irregular sponges such as seat backs.
Optional methods divided into three: Method A, Method B, Method C, user-defined.
