Testing Seat Belts

Image
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)

Testing Thermoplastic Fabric

Image
Testing thermoplastic materials for puncture resistance is recognized as an important aspect for ensuring product quality as stated in the ASTM D4830 standard. Tinius Olsen’s test specific attachment, the model S348, implemented on a H5K-S machine, is best suited for this test. The configuration complies with the key test parameters of ASTM D4830, having a tensile testing machine, ring clamp attachments capable of clamping without slippage, and solid steel rod with hemispherical end & hardness range of 50 to 60 HRC. A specimen of the fabric is clamped between grooved, circular plates of the ring clamp attachment, which is itself secured in an H5K-S tensile testing machine. A steel rod, attached to a load cell in the movable cross-head of the tester,   is lowered onto the specimen at a constant rate until the specimen ruptures; the resultant rupture force, in N or lbf,   of the thermoplastic fabric is captured and reported. Now what makes it even better is that the punct

Wedge Grip Adaptors

Image
Tinius Olsen engineers are continuously working to improve the effectiveness of gripping technology to make testing quicker, easier and more comprehensive.  One of their recent developements are our wedge grip adaptors. These adaptors work with our model HW14 100kN wedge grips & help  operators test smaller samples without the effort of removing these heavy high force grips. This cost effective solution allows smaller capacity grips to be fitted to the testing machine for lower force tensile tests  & makes the work easier.

IDC Connector-Cable testing for critical tensile strength

Image
Today we find IDC Connectors being used in almost all electronic equipment, from computers to automated robotic systems and are used in homes, offices and factories the world over. A loose cable can cause a huge number of headaches for service and maintenance personnel and operators so a program of thorough testing has been put in place by manufacturers to ensure loose cable problems are a thing of the past. Tinius Olsen Engineers have developed a set of grips for these manufacturers to specifically test the tensile strength of cable on IDC connectors. The images here show the grip’s arrangement with Tinius Olsen’s HT33, and HT47, standard grips along with our special grip reference S707 on Tinius Olsen’s H5K single column tensile tester. The model S707 shown here is the lower grip that features a clamping area that can be adjusted to accommodate varying sizes of IDC connector; you can see from the photos that the special grip is designed so that it can be used in both the hor

Testing Syringes and Needles

Image
  Beginning right from the 1 st century AD, syringes have played an important role in human lives. They are now widely used in a variety of applications, including administration of medication, precise measurement of fluid and in the application of compounds such as lubricants. Ensuring the quality of syringes and needles has always been crucial.  Tinius Olsen ’s H5K-S / H5K-T tension and compression testing machine, along with test specific attachment reference S442 as per international standards ISO 7886 and ISO 8537, is capable of providing complete testing solution which includes measuring the force to operate a syringe, freedom from air & liquid leakage, puncture forces and pull off forces. The tests are easily performed from within our Horizon software, and the accurate and reliable results are included in the generated test report. The output graph (of force vs. displacement), gives a graphical representation of the component performance dur

Testing attachments for Baby Pacifiers

Image
Tinius Olsen   engineers have developed more new attachments for the destructive testing of Baby Pacifiers with the key focus being the health & safety of infants. According to a Nationwide survey on ‘Baby Bottles, Pacifiers & Sippy cups’ by US News & World Report, in May 2012, over the past couple of decades there have been over 45,000 cases of problematic pacifiers, in the US alone.              There are a number of tests that can be performed by Tinius Olsen’s attachments on baby pacifiers, including puncture, tear, component pull off, and a Bite Endurance Test. Tinius Olsen grip reference S355 is used with one of our benchtop tension and compression testing machines, and as the pictures above demonstrate, the grip tests the bonding between the teat and the knob/plug; the international test standards that the S355 grip was designed for are EN1400 and ASTM F963-08.   These tests are designed to ensure that the teat stay bonded to the plug, ensuring infants

Testing Latex Rubber Rings

Image
Testing latex rubber rings is not a problem anymore. With Tinius Olsen’s test attachment RT16 you get complete speed control of the rotating grip via a control unit independent of the tensile test speed. Test specimen O-ring is rotated at a programmed speed of 10 to 50rpm as the tensile load is applied; ensuring no particular area of O ring is exclusively subjected to the tensile load.    What makes it more reliable is that it complies with international standards – ISO 4074/9, ASTM D3492, and BSEN 600:1996

Platens for Foam Test

Image
Continuous improvements by Tinius Olsen engineers have made testing foams easier & effective. Flexible cellular materials, including slab, bonded & molded urethane foams, can be tested using Tinius Olsen’s material testing machines & Horizon software. The redesigned platens ensure that air from inside the foam specimen is allowed to escape, by including “air relief” holes; without these holes the trapped air can create back pressure and erroneously increase the indicated compressive strength. These platens are designed in accordance with ASTM D3574.
