The difference between mattress EN 1957 and ASTM F1566 test
1 Difference in durability test of mattress
Both EN 1957 and ASTM F1566 have rolling durability tests, EN 1957 uses a simulated humanoid drum, and ASTM F1566 uses hexagonal drums. Two kinds of loading methods have a relatively principle and standard specifications, the user in the selection of both as much as possible in order to use for different sales and consumer needs, but also a wide range of assessment of mattress quality and function in different environments Case.
2 The difference between the mattress edge durability and the Cornell impact test
EN 1957 edge durability test is the use of human loading pad with 1000N pressure repeatedly loaded mattress, and ASTM F1566 Cornell impact test method to 100 times / min fixed force repeatedly impact mattress 100,000 times. Both the impact principle, the impact speed, the loading pad specifications are different, and the Cornell impact testing machine is more suitable for the soft finished spring mattress, the EN 1957 edge durability test is more suitable for the hard mattress The proposal is from SIMMONS (1870) and Sealy (1881) sharing of two laboratory engineers)
