Machine Instruction:
The mattress fitness and hardness tester is used to test the finished products of spring soft mattress and foam mattress used in home, hotel, etc., and test the hardness, lagging loss rate and fit of mattress. After the test, the grade of sample is evaluated according to the test.
Machine Three Functions:
1. Test Whole Mattress Hardness
2. Test Mattress Surface Hardnessm Core Hardness, Bottom Hardness and Hysteresis Loss Rate
3. Test Mattres Fitness
Testing Standards:
T-SZFA 2003.1-2019 Ergonomic evaluation of mattress – Part 1: Test and evaluation method of mattress hardness classification and distribution
l6.1 method A—— determination of mattress hardness rate
l6.2 method B—— determination of hardness of each layer of mattress
T-SZFA 2003.2-2019 Ergonomic evaluation of mattress, quantitative and evaluation method of mattress fitness
QBT 1952.2-2011 Soft spring mattress for upholstered furniture
