Drying Shrinkage Window at 5.75% measured drying shrinkage: a worked example

Push measured drying shrinkage up to 5.75% and the picture changes. This example computes every intermediate figure at that operating point. a plant needs to decide whether drying shrinkage is inside the approved product window

The inputs for this scenario

  • Measured drying shrinkage: 5.75 % (raised for this scenario; the documented default is 5)
  • Lower acceptable shrinkage limit: 3 % (unchanged)
  • Upper acceptable shrinkage limit: 7 % (unchanged)

Working through the calculation

  • Applying the documented formula (Check whether measured value is between the lower and upper process limits) to the inputs above produces each figure below.
  • At this operating point the engine returns 1 inside for drying shrinkage window, the number this scenario is built around.
  • At this operating point the engine returns 1.25 value for drying shrinkage window nearest margin.
  • At this operating point the engine returns 3 value for lower acceptable shrinkage limit.
  • At this operating point the engine returns 7 value for upper acceptable shrinkage limit.

How this compares with the baseline

  • Against the tool's baseline example, where measured drying shrinkage sits at 5% and the headline result is 1 inside, this scenario lands almost exactly on the baseline at 1 inside.
  • It tests whether a measured drying shrinkage percentage falls inside a defined lower-to-upper spec window and computes the distance to the closest limit. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Drying Shrinkage Window: 1 inside (headline result)
  • Drying Shrinkage Window nearest margin: 1.25 value
  • Lower acceptable shrinkage limit: 3 value
  • Upper acceptable shrinkage limit: 7 value
