41、y Information)A1. OPTICAL METHOD FOR MEASUREMENT OF THICKNESS OF COATINGA1.1 ScopeThis is a method for measuring the thicknessof the coating over fiber backing or reinforcing fabric.A1.2 Measurement Method:A1.2.1 PrincipleThe thickness of coating material overfiber, fabric, or scrim can be observed

42、with a standardreflectance microscope. Measurement is made with a calibratedeyepiece.A1.2.2 Apparatus:A1.2.2.1 Microscope, 60X with reticle.A1.2.2.2 Light SourceIf light source on the microscope isnot adequate, use a small high-intensity lamp.A1.2.2.3 Stage Micrometer, 0.0254-mm (0.001-in.) divi-sio

43、ns.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 source.A1.2.3.3 Position the reticle eyepiece and the micrometersuch that the scales are superimposed. Focus the reticle byturning the eyepiece. Focus the

44、specimen and reticle by turningthe verticle adjustment knob.A1.2.3.4 Locate a point at which both scales line up. Countthe number of micrometer divisions away. Measure to thenearest 0.0125 mm (0.0005 in. or 0.5 mil). The calibration maybe optimized by increasing the number of divisions measured.A1.2

45、.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 micrometer divisionsMD!, then:1 RD!54.5/4 MD! or 1 RD!51.125 MD! (A1.1)Since 1 micrometer division is also equal to 25.4 m 0.001in. or 1.0 mil!, t

46、herefore:1RD5 28.6 m 0.001125 in. or 1.125 mils! or the calibration factor.(A1.2)A1.2.4 Specimen Analysis:A1.2.4.1 Carefully center a sharp single edge razor orequivalent over the fiber intersections along the xx axis.A1.2.4.2 Make a clean bias cut completely through thesheet.A1.2.4.3 Remove the raz

47、or-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 thethread intersection by counting the number of reticle divisions(to the nearest one-half division).D5019073

48、A1.2.4.5 Sample three areas of the coatings and average theresults.A1.3 Calculation and ReportMultiply the number ofreticle divisions representing the thickness of the coating the bycalibration factor. Report the average results from three areasof the coating to the nearest 12.7 m (0.0005 in. or 0.5

49、 mils).A1.4 Precision and Bias:A1.4.1 PrecisionMeasurements are accurate to 612.7 m(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 accepted reference materialsuitable for determining the bias for measuring coating thick-ness, no statement on bias is being made.ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentionedin this standard.
