OPTICAL METHOD FOR MEASUREMENT OF THICKNESS OF COATINGA1.1 ScopeA1.1.1 This is a method for measuring the thickness of thecoating over fiber bac
37、king or reinforcing fabric.A1.2 Measurement MethodA1.2.1 PrincipleThe thickness of coating material overfiber, fabric, or scrim can be observed with a standardreflectance microscope. Measurement is made with a calibratedeyepiece.A1.2.2 Apparatus:A1.2.2.1 Microscope,603 with reticle.A1.2.2.2 Light So
38、urceIf light source on the microscope isnot adequate, a small high-intensity lamp may also be used.A1.2.2.3 Stage Micrometer, 0.0254-mm (0.001-in.) divi-sions.A1.2.3 Calibration Procedure:A1.2.3.1 Place a standard reflectance stage micrometer inplace of the specimen.A1.2.3.2 Turn on microscope light
39、 source.A1.2.3.3 Position the reticle eyepiece and the micrometersuch that the scales are superimposed. Focus the specimen andreticle by turning the vertical adjustment knob.A1.2.3.4 Locate a point at which both scales line up. Countthe number of micrometer divisions away. Measure to thenearest 0.01
40、25 mm (0.0005 in. or 0.5 mil). Increasing thenumber of divisions measured may optimize the calibration.A1.2.3.5 Repeat the calibration three times and average theresults. A calibration example is given below:If four reticle divisions (RD) are found equal to 4.5 mi-crometer divisions (MD), then:1 (RD
41、) 4.5/4 (MD) or (RD) = 1.125(MD)Since 1 micrometer division is also equal to 25.4 m (0.001in. or 1.0 mil), therefore:1 (RD) = 28.6 m (0.001 125 in. or 1.125 mils) or the calibration fac-torA1.2.4 Specimen Analysis:A1.2.4.1 Carefully center a sharp single edge razor orequivalent over the fiber inters
42、ections along the x-x axis.A1.2.4.2 Make a clean bias cut completely through thesheet.A1.2.4.3 Remove the razor-cut section and mount in com-mon putty with the cut surface facing upward.A1.2.4.4 Observe the cut surface with the eyepiece reticle.Measure the thickness of the coating on either side of
43、thethread intersection by counting the number of reticle divisions(to the nearest one-half division).A1.2.4.5 Sample three areas of the coatings and average theresults.A1.3 Calculation and ReportA1.3.1 Multiply the number of reticle divisions representingthe thickness of the coating by the calibrati
44、on factor. Report theaverage results from three areas of the coating to the nearest12.7 m (0.0005 in. or 0.5 mils).A1.4 Precision and BiasA1.4.1 PrecisionMeasurements are accurate to 6 12.7m (0.005 in. or 0.5 mils) when the thickness is about 0.5 mm(0.020 in. or 20 mils).A1.4.2 BiasSince there is no
45、 accepted reference materialsuitable for determining the bias for measuring coating thick-ness, no statement on bias is being made.D 67543ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentionedin this standard.
