 Ropes tend to have an explosive nature on failure and with sudden, violent breaks and it’s this explosive tendency that makes the strength testing of ropes very challenging. Any measurement system that directly contacts the rope must be robust enough to withstand these violent failures; typically this means the measurement system is heavy and/or bulky and could be a potential dangerous projectile when rope specimens undergo a violent break. For these kinds of tests, Tinius Olsen recommends the use of a non-contact video extensometer for the measurement of strain.
 The Tinius Olsen video extensometer is ideal for testing ropes on horizontal or vertical  testing tensile testing machines since it employs a non-contacting technology and can be suitably placed away from the rope, or behind a clear plastic screen, to prevent damage to the extensometer however violent the rope break event. In addition, since the extensometer doesn’t touch the specimen, no localised stress points, that could induce a premature break, exist. The captured and stored video image of the test contains the full high resolution strain data and can be replayed to support further analysis, and can also be retained as the “permanent” test record. The Tinius Olsen video extensometer conforms to the international standards BS EN ISO 2307 and is compatible with both Tinius Olsen, and non-Tinius Olsen testing machines.

One of the oldest and largest manufacturers of thermoplastic polyurethanes (TPU) in the world is adding more MP1200 melt indexers to their quality control labs. They have more than 50 years of experience and a worldwide network that includes design, manufacturing, R&D, applications / technical service labs, and have been using Tinius Olsen equipment for years; the current program involves replacing their existing equipment of model MP987 melt indexers that have been in service for 25+ years and replacing them with new MP1200 machines.
Markets for the engineered polymers they manufacture are numerous and growing every year. Look around and chances are good that you’ll spot one of their engineered polymers in action: running shoes; soft grip handles on wrenches and screwdrivers; tough enough to be used as jacketing to protect wires and cables from chemical and environmental damage; and even in garden hoses. Seals and gaskets of bull dozers and backhoes as well the side moldings of the family car can all claim an engineered polymer as a component.
By verifying the flow characteristics of the variety of TPUs manufactured, they are ensuring that users and molders are able to use these different engineered polymers without worrying that their manufacturing processes and equipment are at risk. |

CPAC Roof Tile Company, a sister Concern of Siam Cement Group of Thailand, is one of the leading manufacturers of roof tiles in Thailand. This company has put up its faith in Tinius Olsen Machine for testing the quality of the product being manufactured by them. For testing 300x400mm to 400x400mm tiles, CPAC is using Tinius Olsen’s H50KT-W machine while implementing Quality Control. H50KT-W has a wider frame which provides larger test area for larger samples. More than 50 to 100 samples testing per day is made easy by the use of Tinius Olsen Machine. The attachment used in the machine helps by holding the sample firmly before starting the test. Our distributor Calserve along with the customer has designed the attachment to follow the standard TIS 535.

We're constantly asked about customizing our Super L test frames to accommodate different shapes and sizes of specimen, and indeed we have standard options available for the lengths of pulling screws and columns, but recently we had our first request, in 133 years, for a non-magnetic loadframe.
 A division of the Russian Academy of Science is performing a series of experiments to study the relationship between stress loading and magnetic fields, so having a loading frame, with a 60,000 lbf (300kN) capacity, made from steel was obviously going to have a detrimental effect on any magnetic measurements. Working closely with the customer, we developed a stiff loading frame that uses aluminum crossheads and were able to achieve the goal of no magnetic "interference" from the test frame during the course of their tests.
On the left here you can see the machine in question with the aluminum crosshead; the same machine can be seen in the front in the photo on the right here, as a further example of the kinds of customization available, the machine next to it (all waiting to go into our paintshop) is also a 60,000lbf capacity Super L but has an adjustable height top crosshead on columns that are an extra three feet in length, with strategically placed locations for the top crosshead to be anchored.

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.

The world of testing has changed dramatically in the last 20 years with students now able to spend their time interpreting and using test data rather than acquiring test data. The days of using a chart recorder, or XY plotter, connected to a testing machine to generate a graph and then painstaking use of rulers to draw lines of best fit, calculating slopes, maximum values (… and what was the FSD?) etc. are long gone; gone too are the days of simple software that controlled the machine and reported basic values that then had to re-entered into different software packages to generate basic SPC results on the system or generate simple reports. Horizon software from Tinius Olsen is the next evolution in testing tools that allows users to spend their time using results rather than generating results. Key features of Horizon include:
- Run and monitor multiple machines, and machine types, from a single pc
- Large database of testing routines written in accordance with ASTM, ISO, EN etc standards
- Generation of custom test routines
- Calculation of custom results from multiple inputs/sources
- Generation of custom reports using data from multiple inputs/sources
- SQL database foundation allows large databases which users can share or view across a network
These are just some of the key features behind Horizon that lets us state that Horizon is a tool that, unquestionably, allows you to work smarter, not harder. |
