DeFelsko Standards Certified Plastic Shims


Certified Plastic Shims

Certified Plastic Shims (foils) provide an economical alternative to coated metal plates. They have a reduced accuracy of ± 2 μm (±0.08 mil). A coating thickness gage measures shim thickness when this shim is placed over a smooth metal surface (zero plate).

Alternatively, they can be placed over an uncoated metal substrate. They are not suitable for use with magnetic pull-off gages.

Overview of Shims

  • Simulate a coating over a particular substrate material or shape. Gage performance can be conveniently verified on a regular basis as required by some international test methods
  • For use with all Type 2, electronic coating thickness gages
  • Protects the probe from damage or premature wear when placed over hot or abrasive surfaces
  • Can be placed on top of soft or tacky coating films to obtain thickness measurements without the gage probe depressing the coating film
