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

Certified Plastic Shims

• Certified shims provide an economical alternative to Coated Metal Plates but have a reduced accuracy
• Each shim is packaged in their own plastic protective pouch
• Certificate of Calibration showing traceability to NIST is included with each shim or set of shims
• Certified and labeled in both Metric and Imperial units
• Certified Plastic Shims are available in the following thicknesses (all thicknesses are approximate)
