INVESTIGATIONS DIRECTED TOWARD DEVELOPMENT OF A DIRECT READING THICKNESS GAGE FOR PAINT FILMS ON WOOD

THIS IS THE FINAL REPORT OF STUDIES DIRECTED TOWARD THE DEVELOPMENT OF A DIRECT READING PAINT FILM THICKNESS GAGE FOR WOOD USING BACKSCATTERED BETA RADIATION FROM A SR-Y-90 SOURCE. THE RESULTS OF RESEARCH REPORTED HERE SHOW THAT THE RUGGED PORTABLE FIELD MODEL OF THE PAINT FILM THICKNESS GAGE THAT WAS DEVELOPED CAN BE USED TO MEASURE THICKNESSES OF THREE COMMONLY USED EXTERIOR SPECIFICATION PAINT SYSTEMS FOR WOOD, I.E. TT-P-102, TT-P-0055A, AND TT-E-489. CALIBRATION CURVES ARE GIVEN INDICATING THAT THE GAGE CAN MEASURE THICKNESSES FROM 0.5 TO 30 MILS AND HAS AN ACCURACY OF ABOUT 5%. /AUTHOR/
