How to do mattress hardness test

Product catalog summary
Introduction: The mattress hardness test is designed to evaluate the firmness of different parts of a mattress, including the middle area, four corners, and edges. This test helps in comparing the internal and external characteristics of the mattress.
Testing Procedure:
  • Set the test site on the mattress to ensure consistency across samples.
  • The default impact height is calculated from the top of the sample test site. The hammer is raised to this height to begin the test.
Professional Testing Method:
  1. Initial Measurement: Conduct the initial measurement after 100 cycles of loading at the start of the durability test. The test point should be at the center of the roller test area.
  2. Standard Environment: Place the test product in a standard environment for a specified time before each test to restore balance.
  3. Preloading: Use a spring soft mattress surface softness tester, preloading to 1000N at the loading point, then unloading, and repeating 3 times. Each preload cycle should not exceed 30 seconds, and measurements should be taken within 30 seconds after the last preload cycle.
  4. Load Deflection Measurement: Ensure an even number of measurement conclusions. Increase the load to 1000N, recording the loading deflection curve with at least 250 points from 0 to 1000N. In the range from 0 to 450N, record no more than 2N for one loading point.

How to do mattress hardness test-1

How to do mattress hardness test? The mattress hardness tester can be used to test any different parts of the sample, including the middle area, four corners and edges of the sample, to compare the internal and external characteristics of the sample. Once the test site needs to be compared is set, the instrument should be used to test the same site for each sample. The default impact height of the instrument is calculated from the top of the sample test site. Once the top of the sample test site is set, the hammer will be raised to the set height and the test will start until the end of the test. For more professional testing, use a mattress hardness tester. Mattress hardness tester's testing method for mattress hardness: 1. The initial measurement of the mattress hardness tester should be carried out after 100 cycles of loading at the beginning of the durability test. The test point should be located at the center of the roller test area. 2. Before
