Materials testing platform technology overview

Tinius Olsen Materials testing platform technology overview

Overview of a materials testing platform based on a U series 300kN testing machine. Same technology is available for lower capacity materials testing machines from 10kN up to 300kN bench and floor standing systems.

Tinius Olsen Universal Testing Machine

Tinius Olsen H300KU with Horizon Software

 Metals, Plastics, Composites all can be thoroughly tested and analysed on this triple camera extensometer Tinius Olsen work station– This is a truly a UNIVERSAL TESTING MACHINE from Tinius Olsen; 300K-U, 300kN load cell, 1000 degree C  furnace, -70 to 300 degree C chamber, 3 camera video extensometer system (cameras can be used together or individually), tie rods for threaded specimens, hydraulic tensile wedge grips, compression platens, flex bend attachment and Horizon touch enabled materials testing software. All the key parts and accessories are easily handled in and out of the test area using TO’s new accessory handling system – so all accessories are stored on the handling system ready to be simply pushed into place by the operator.

HT19 Split Collet Grips for turned dumbbell test specimens

Tinius Olsen’s HT19 split collet chucks grip is designed for applications involving smaller turned dumbbell test specimens. The HT19 has a number of options to accommodate various size dumbbells with each split collet chuck set matched to a particular dimension of specimen. The HT19 grip a maximum capacity of 20kN and should not be used with a loadcell smaller than 50N capacity.


Key parameters include diameter of turned gauge length, diameter of larger turned end section and the radius of the shoulder joining the end section and the gauge length.


Tinius Olsen has higher capacity options for more traditional size specimens, so to learn what options are available for your application, please contact us.

PT190 - 90 degree Peel Test Attachment with moving Base Sledge


PT190 is a 90° peel unit comprising of one HT50 ultra-light vice grip (as standard) and a "horizontal Test bed". It is specifically designed for peel testing of the bond between copper and Printed Circuit Boards (PCB’s) as well as other laminate/layer bonded specimens, but can be used in a host of other peeling type applications. The PT190 is typically installed on a Tinius Olsen H5KS, or similar low capacity tensile tester and has a maximum capacity is 1.5kN (300lbf) with a minimum load cell of 50N.
Prepared samples (150x50mm max.) are held on the test bed using a clamp with one end of the specimen inserted into the top clamp. The test bed incorporates a moving sled, mounted on precision bearings, which is directly attached to the moving crosshead of the test frame. As the crosshead moves up, the bad is pulled horizontally, so maintaining a peel angle of 90° throughout the duration of the test.

HT58 grip for lightweight thread and yarn testing applications

Tinius Olsen specifically developed the HT58 lightweight pneumatic grip for easy and repeatable thread/yarn testing. Designed for use with 10N load and calibrated for use between 10-1000 grams, the HT58 is used on the Tinius Olsen H5KS tensile tester.
With a gripping pressure of 150N (15kgf), the HT58 eliminates the slip and its unique gripping face design prevents premature specimen breaks in the jaws. Its design allows quick and
easy loading, for continuous commercial testing and accurate setting for repeatable gauge length choice.

High Elongation U Series

Tinius Olsen provides all kinds of customizations for our testing equipment and the most recent series to be modified is the U series.
The U series machines are floor standing tension and compression materials testing machines, used to test the physical strength of a vast range of materials, and are available in maximum capacities from 100kN to 300kN.  Until now the maximum crosshead travel has been limited to 1,200mm, but with these new custom frames, this maximum has increased to 2,000mm.
To achieve this 66% increase in test height, without increasing the machine height (of 2.85m) the machine’s controls and electronics are removed from the test frame and relocated into a separate housing, as seen in the artist rendition here.  All other machine performance specifications remain the same.

T Slotted Tables – why are they so useful?

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 compensates for any off centered loading.
Tinius Olsen is able to make and supply all sizes of T-slotted tables across its range of S series, T series, U series, Super L series and Electomatic series of tension and compression testing machines, to meet user’s needs in testing large or unusually shaped specimens.

Testing Wet Tensile Strength of Absorbent Paper

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 the 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 & performance of the tissue/absorbent paper.

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 accordance with the international standard ISO-IEC 10373-3.
TO testing machine with test specific grips HT55/S460/S997 holds the smart card and apply the test forces either to destruction to determine the maximum strength capability or non-destructive but repeatedly loaded i.e. a cyclic test to analyze the performance. Through the Tinius Olsen test and analysis software HORIZON, smart card manufacturers and users can set up Pass/Fail limits for each parameter tested; the system automatically tests the smart card performance against these limits and reports performance.
