Certified & Non-Certified Plastic Shims

For use with magnetic, eddy-current and ultrasonic coating thickness gages.
(Not intended for use with Type 1 magnetic pull-off type gages)

Shims Overview

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
Certified Plastic Shims are available in the following thicknesses (all thicknesses are approximate):

Order Code	Approximate Thickness	Color	Accuracy
CS1	25 µm (1 mil)	Orange	±2 µm (±0.08 mil)
CS2	50 µm (2 mil)	Red
CS3	75 µm (3 mil)	Green
CS5	125 µm (5 mil)	Blue
CS10	250 µm (10 mil)	Brown
CS20	500 µm (20 mil)	Yellow
CS40	1000 µm (40 mil)	White
CS60	1500 µm (60 mil)	Black
CSS	Complete set of 8

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

Non-Certified Plastic Shims

Provide a quick operational check of the instrument by allowing the user to perform practice measurements
Can be used to protect the probe when measuring on tacky, rough or hot surfaces
Labeled in both Metric and Imperial units
Available as a set of 5 (below)

Approximate Thickness	Color	Accuracy
25 µm (1 mil)	Orange	± 20%
50 µm (2 mil)	Red	± 10%
125 µm (5 mil)	Blue	± 5%
250 µm (10 mil)	Brown	± 5%
500 µm (20 mil)	Yellow	± 5%

A package of 5 non-certified shims is included with all DeFelsko electronic coating thickness gages (Type 2).

Note: While DeFelsko inspects non-certified plastic shims to ensure they are within the nominal stated accuracy, they are not traceable to any national or international standard.
