Consulting about measuring softness

Some topics:

Softness testing for clients

Companies hire us to measure the softness of products and materials. 

  • Competitive Analysis - to see how their own products compare against products made by competition
  • Product Development - to quantify the differences between experimental variants
  • Marketing - to ensure that advertising claims about softness are based on credible test methods

Training in testing and measuring softness

Companies hire us to train their people how to measure softness with efficiency and accuracy.  We teach the following softness measurement methods.

  1. Control Method - good for process control and routine quality assurance, but not as accurate as the other tests (especially when comparing samples that are made very differently)
  2. Panel Method - best for accuracy, for selecting reference standards, and for competitive analysis, but can only handle a maximum of 9 samples at a time (including reference standards)
  3. Two-Out-of-Five Method - best for demonstrating whether a difference between two samples can be detected or not
  4. Advanced Methods - when testing and comparing more than 9 samples together with greater accuracy and precision than the Control Method
