The Testing Times

T-slotted tables are extremely useful when they’re used with materials testing machines because they provide an easy way to insert and clamp non-standard or large test samples. T-slotted tables themselves can come in all shapes and sizes – the one on the right here was designed to fit one of our 10,000lbf twin column bench-top testers (which itself is mounted on a frame) and is used by a conduit manufacturer to perform flexural tests on their products. The T-slots allow easy location of the flexural jig supports (which are anchored in the slots) so switching between different products is simple and quick. With all T slotted tables, the loading point MUST still be in the center of the specimen and in the same plane as the loadcell – any off-centered loading can give erroneous results and can also damage loadcells. This is true for all machines except Tinius Olsen’s Electomatic series of testing machines whose unique design, and key feature, allows and compen

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 &

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

Testing long compression springs comes with many challenges, the most severe of which is the tendency of the spring to buckle under compression forces. Tinius Olsen engineers developed a solution to ensure accurate and reliable test results, by using a support post fitted to the lower compression platen.  This support post centers the spring and provides support during the initial stages of compressive loading, when buckling is most likely to occur.  The load cell is mounted on the machine base and the support post passes through the cross-head as it compresses the spring, preventing and buckling of the spring. T his configuration can be easily applied with a standard U series Tinius Olsen machine. For more information on Compression/Tension testing machines, click here

Many of the world’s major seat belt manufacturers use Tinius Olsen tensile testing machines to test seat belts and associated components to prove strength and performance. Tinius Olsen’s H100K-U tensile testing machine along with test specific grips HT43 proves to be the best solution for testing seat belts complying with international standards such as ASTM D6775 and BS 3254.  Seat belts store a great amount of energy before breaking, hence the break is violent. One of the nice feature of Tinius Olsen machines is TO offers a range of safety screens compatible with its U series tensile machines to protect users and contain component fragments. And the Horizon software produces the output graph (force against displacement) which gives a graphical representation of the seat belt performance during the test.   Quick Facts: A typical seat belt in a modern car can withstand a tensile breaking force in access of 2.5 tons (25kN)
