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

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

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
