The Testing Times

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 ...

  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 perfor...
