S-701 Thin Film Thickness Standards
S-702 Thick Film Thickness Standards
The best and most reliable means of calibration or checking the accuracy of thickness gages is using film thickness standards. An optico-mechanical gage such as the Tooke Paint Inspection Gage, if set up correctly, will not be subject to appreciable calibration change, except by gradual wear of cutters and guide studs. On the other hand, “surface proximity gages,” such as magnetic, inductance, or eddy current types generally require calibration before any series of measurements – and often within a series of measurements, especially if the surfaces are variable in type and structural thickness.
Standards are a fundamental requirement for reliable thickness measurement. The Micro-Metrics S-701 and S-702 Film Thickness Standards are supplied as individual chips measuring 2 by 3 inches, in sets of six pieces in a calling-card-sized plastic folder. Plastic materials are polyester and acetate in the thin set (1–10 mils) and unplasticized vinyl in the thick set (10–60 mils). Each film is identified by color. Each set contains six chips of the following film thicknesses. Nominal and “Best Average” thicknesses of plastic films are printed on the Film Standard package label. The best average values are the results of approximately 100 samples measurements on the film batch. The thickness of individual film specimens is not certified. |
