Measurement and Testing

There is an old adage that an ounce of measurement is worth a pound of analysis.  This is particularly relevant in assessing risk.  An analysis is always as good as the assumptions it is based on and is easily open to dispute.  Measurement however, is more definitive. 

Good measurements when coupled with equally good analysis allow:

  • the failure analyst to confirm their hypotheses and develop predictive models to enable them to assess the effect of changes during remedial design;
  • the designer or auditor to calibrate their models and thus determine the margin to failure more accurately;
  • the Owner/Purchaser of equipment to determine why the equipment is not performing to specification or if it is fit-for-purpose.
EAnD have a comprehensive list of test equipment for all kinds of measurements. 
  • static strain measurements of up to 127 channels
  • digital dynamic strain measurements of up to 64 channels
  • analogue dynamic strain measurements of up to 30 channels
  • acceleration and vibration measurements
  • dynamic pressure measurements up to 70 MPa
  • telemetry gear: 2 x 3 channel and a number of single channel units
  • Impact hammer tests

We have computer software which allows for fast on the job analysis of any signals recorded.

Instrumentation set up from a large strain gauge test for a BOBO passenger locomotive. 124 strain gauges were applied to the locomotive. Special software was developed so that stresses from all the gauges could be obtained and monitored in real time. The software also signaled an alarm if the stress in any of the gauges exceeded a preset value.
