Certified Plastic Shims, Set of 8, by DeFelsko

• 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.

DeFelsko Certified Plastic Shims

Certified Plastic Shims (foils) provide an economical alternative to coated metal plate standards with a reduced accuracy of ±2 µm (±0.08 mil). Gage performance can be conveniently verified in the field or in the lab on a regular basis as called for by some international test methods. Shims are placed over a smooth metal surface (zero plate) and a measurement taken. These strips of flat polyester can be used to adjust (optimize) a coating thickness gage in the intended range of use directly over the customer's uncoated substrate.

Certified Plastic Shims are sold individually or as a complete set of eight. Each Certified Shim is individually serialized and labeled with its measured thickness (mils and microns) obtained with measurement equipment traceable to NIST. They are packaged in their own plastic protective pouch. One Certificate of Calibration showing traceability to NIST is included with each shim or set of shims. Their labeled thicknesses are accurate to within ±2 µm (±0.08 mils). They are for use with electronic magnetic, eddy-current and ultrasonic coating thickness gages.

• Certified shims provide an economical alternative to Certified Coated Metal Plates, but have reduced accuracy.
• Certified Plastic Shims are available in thicknesses shown (all thicknesses are approximate).
• Each shim is packaged in its 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.
