Testing Wet Tensile Strength of Absorbent Paper

Image
On the way of innovation, Tinius Olsen now uses its Tensile Testing Machine to put up a test to measure the wet tensile strength and performance of tissue and absorbent paper. Wet tensile strength is the maximum force supported by the unit width of a wet test piece of tissue/absorbent paper until the onset of rupture using a tensile test. EN 12625 defines th e preparation of the test specimen in terms of the edge quality and dimensional tolerances . The test specimen is placed into a Tinius Olsen tensile testing machine upper clamp so that a loop is produced around what is called the “Finch” soaking device bar; the soaking vessel containing water is raised allowing soaking for 15 seconds, the tensile force is then applied & once the specimen ruptures, the soaking vessel is removed. Results are automatically reported through Horizon test software in terms of Mean wet tensile strength (N/m) & Relative wet tensile strength (%) which qualifies the strength &

Testing Smart Cards

Today, in this smart world we are having many smart devices around us and smart card is one them. They are proving to be much in demand with proximity readers with their increasing use as means of E-commerce, healthcare informatics, bank issued smart cards (credit cards/debit cards), SIM cards for mobiles and Personnel Identification really starting to cross from industrial/commercial use into personal use e.g. home entry, auto start cars and recall of personal settings, loyalty programs in retail, securing digital content etc. One of the important aspect that manufacturers worldwide take care of is that the smart cards need to be physically enduring devices. Using a Tinius Olsen testing system ( H5K or H10K ), thorough analysis of a smart card’s physical strength can be done. It is possible to subject smart cards to a range of physical strength tests including; bend/flex, tear, peel and "Chip" to card bond strength. The tests performed are in accor
