Advancements in Foam Porosity Measurement

Image
The first version of IDM Instruments’ Foam Porosity Tester F0016 was designed and released in the 1980s, in accordance with global industry standards, and was used to determine the ease with which air passed through a cellular structure, namely foam, by comparing the relationship between pressure and flow when subjected to different foam samples. It used vacuum chambers with manometers and was controllable via a manual dial to fine tune flow. This version was purely analogue and required fine use of the dial and flow tubes to be able to give accurate test results. Due to the purely analog design, it was difficult to achieve accurate yet repeatable test results. After more design and upgrades, the second version Foam Porosity Tester F0023 was released in late 2001. Once again improving the accuracy of foam porosity testing. This model boasted variable flow ranges, allowing for more ranges of conditions of testing foam porosities. A huge feature of this model was

Cobb Moisture Absorption Test Ring & Roller This method for measuring water absorption of sized papers is used all over the world. A dry test piece of suitable paper is placed under the cylinder. The 100ml of water is poured over the test piece. After a specified time the water is poured off and the test piece is placed on standardized blotting paper. Another blotting paper is placed on top of the test piece and the excess water is removed by means of the roller. The test piece is then weighed again and the results are calculated and reported as absorption in grams per m2, according to the standard method.
