EN 1957 Furniture Testing Equipment Mattress Hardness Tester
Mattress hardness tester is used to evaluate the firmness of the mattresses, which is applied to laboratory test and quality control in production line. The applicable range: foam products, mattress manufacturing, car seat manufacturers and other industries.
Universal hardness and hardness measurements are based on a physical property called indentation force deflection. The hardness is calculated by determining the ratio of the thickness after being compressed and the original circular indentation force. The computer receives the signal from the sensor and record the extent of indentation when the platen stresses on the specimen. In order to compare the test results,the size and thickness of specimens must be the same.
