Foam Hardness Kpa at Summer Mannix blog

Foam Hardness Kpa. To obtain the value, a 50 square inch circular plate is pushed into the foam surface, stopping at a given deflection and reading the load. (determination of density), bs en iso 2439. The higher the kpa value, the firmer the foam. The lower it is, the softer the foam. The compressive strength in kpa is given as an indication in average value. In kpa, it expresses resistance to compression at 40% depression. Compression load deflection hardness iso 3386/1 5.0 kpa It is expressed in kilo pascal (kpa) or in newton (n) according to the specific measurement tests. For example a 25 percent ild of 30 means that it takes 30 pounds load to compress a 4 inch thick piece of foam to a 3 inch thickness. Physical properties are measured using test methods described in bs en iso 845:1995.
