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

Bearing Strength of Plastics

Image
Tinius Olsen Engineers have designed a new custom attachment for testing the bearing strength of plastics. This attachment is used with Tinius Olsen’s  S and/or  T series of benchtop tensile testers and Horizon software to report bearing strength.  The bearing strength test is designed to replicate the loading on plastics sheet, or plastics products, where rivets, bolts or similar fasteners are used to join sections and show the bearing stress versus the deformation of the hole for rivet/bolt etc. The allowable deformation of the hole in the material should be enough so that there is no looseness of the joint.  As the picture shows, the grip includes an LVDT Extensometer that precisely measures the amount of hole deformation. This attachment follows the guidelines of ASTM D953.
