A tension and compression testing machine, irrespective of capacity, is a significant  investment. Whether it is used for QC\QA monitoring, R&D investigations, or as an aid to material’s performance education, it is invariably an investment that is required to last. We have found that in a surprisingly short time the original testing requirements evolve into new territory; reasons for this evolution could be a material / process / component change, or an update to an international testing standards e.g. ASTM, ISO, EN, JIS, IN, GB, GOST , or simply the consequence of “why don’t we try testing this….” which then takes over. This does not necessarily mean the original testing machine investment is at an end, on the contrary, we have found that by simply adding some basic accessories the original investment can continue to reap a return.  Accessories, such as extensometers, test specimen griping solutions, temperature chambers and furnaces can all be added to existing testing systems to ensure it keeps pace with the evolution in changing testing needs.
Tinius Olsen offers a range of high quality, cost effective, international testing standards compliant accessories which are not only compatible with Tinius Olsen tension and compression testing machines but also compatible with those supplied by other manufacturers including from the US, German, Japan, Taiwan and China. Specimen grips - with industry standard B, C, D type or 5/8” or ¾” connectors, no need for adapters reducing the working test area unnecessarily and/or adversely impacting alignment. Extensometers - the Tinius Olsen 500L, with its scan rate of 320 times per sec , 600mm field of view and 10µm resolution, or the exciting Tinius Olsen video extensometer that ASTM E83 Class B1 compliant even for metals testing, with unique features - no special lighting requirements, multiple gauge lengths and post test analysis on real time video. Temperature chambers and furnaces – options for hot and cold units - 70 to + 1100°CFor examples of custom solutions compliant with international testing standards visit http://thetestingtimes.blogspot.com/ For details of accessories and how they can be integrated with your tension compression materials testing machine contact Tinius Olsen http://www.tiniusolsen.com/contact-us.html |

 We have just finished the on-site upgrade of several melt indexers used by a well known processor in Brazil. The melt indexers were upgraded with our pneumatic purge and cleaning accessory since two labs were consolidated into one to save costs. These purge and cleaning attachments allow for a more automated approach to melt index testing and significantly reduces the amount of individual attention operators have to give to each machine, and also reduces the risk of operator fatigue while increasing productivity, especially with the cleaning process. |

 If your melt index values are either too high or too low when you compare your results with suppliers/customers, here is a shortlist of items to investigate to rule out the obvious:
2. Is the machine level? Any melt indexer machine must be levelled properly before use. We supply a piston level with each machine and this should be placed on the top of the piston to ensure the piston, and barrel, is perfectly vertical; if these aren't vertical the piston could potentially get stuck in the barrel and give erroneous melt index results. |

 Crew Systems Corporation, a designer, developer and manufacturer of personal military life support equipment, has invested in another testing system from Tinius Olsen. With this new system Crew Systems staff will be testing, primarily, the strength and compressibility of various materials used in upper torso protection for military pilots. Having identified a need for another testing machine, Crew Systems’ Quality Manager, Tom Matkosky, made inquiries with many different suppliers and investigated the full range of equipment and capabilities of all these manufacturers and quickly settled on Tinius Olsen as their supplier of choice. “The entire staff at Tinius Olsen, from sales to servicing, were quick to respond to all of my inquiries and, I felt, the only supplier who not only actually listened to my needs and made sensible testing solution suggestions, but also worked with me and my budgetary constraints” says Matkosky. “Lives depend on the integrity of our products, so equipment that accurately measures the quality of our products is of primary importance to us, and, of course, our customers.” continues Matkosky, “I am extremely confident both in the capabilities of our new testing system, and with the top-grade support I get from Tinius, and because of this I’m equally confident we can continue to provide the product quality and integrity vital to our customers’ needs.” |

 One of the most widely used medical devices is the contact lens worn by millions of people daily.
The material science and technology in such a small device is amazing in the form of soft and hard lens with varying degrees of air permeability. Performing a strength and elastic stretch test on such a device is challenging, the lens must be held to prevent slippage during the test but not to cause fracture or damage, ambient conditions need to be managed simulating conditions of use. Another important test performed on contact lenses is a tear test, simulating someone rubbing their eyes while they are wearing lenses. This too requires special grips that can prevent slippage but still not damage the sample or induce a premature break or tear. Tinius Olsen has the expertise having successfully supplied strength test systems to contact lens manufacturers. |
