During the Innovations in Rubber Design Conference of IOM3, which is being held 7-8 December 2016 at 4 Hamilton Place, London, UK, an official from Tavdi Company Inc will be presenting the Yerzley Mechanical Oscillograph (AYO-IV).
The ASTM D11.10 subcommittee has incorporated the latest automation of the AYO-IV test method by Tavdi Company Inc into the D945-16 Standard.
This instrument is completely computerized and equipped with the latest user-friendly software, eliminating all operator induced errors in data evaluation. No longer is there a need for graph paper, nor the required interpretation of the resulting graph; all calculations are automated so that results are available once the test is completed. A typical compression or shear test takes less than five seconds, after which the resulting trace and the calculated parameters are displayed at natural frequency of that sample.
An additional parameter, tangent of delta, the measure of energy loss due to damping, is also calculated and reported. AYO-IV predicts the mechanical properties of rubber, plastics and other polymers.
