WebNov 8, 2011 · The test is executed by a circular metal indenter applying downward force into the foam sample as it rests on a flat surface. The indenter pushes into the foam until it is compressed 1 inch, 25 percent of the sample’s height. The pounds of pressure needed by the machine to compress the foam one inch is the ILD number. If 30 pounds are ... WebA novel foam-based colorimetric alcohol sensor was developed for the detection of alcohol in saliva. Detection was based on the color change of a potassium dichromate-sulfuric acid solution absorbed by melamine foam. In the presence of alcohol, the orange colorimetric sensor changed color to brown, green and, ultimately, blue, depending on the …
