PHILOSOPHY OF TESTING PROGRAMS

TEST PROGRAMS ARE DESIGNED TO ESTABLISH PRODUCT BEHAVIOR PATTERNS WITH ENOUGH RELIABILITY TO ESTABLISH WARRANTIES. ATTEMPTS TO DECREASE THE TIME FACTOR ALSO DECREASE DATA RELIABILITY. PAINT FILM FAILURE IS SO COMPLEX THAT ARRHENIUS OR EYRING METHODS CANNOT BE APPLIED. RELIABILITY IS DEPENDENT ON MAINTAINING THE PROPER RELATIONSHIP OF MANY STRESSES, TO KEEP THE FAILURE MODES IN PROPORTION. PRESENT ACCELERATED METHODS FAIL IN THIS RESPECT. A NEW APPROACH IS PROPOSED, MAINTAINING A NORMAL BALANCE OF STRESSES, AND USING SENSITIVE INSTRUMENTATION TO DETECT EARLY CHANGES WHICH CAN BE CALIBRATED AND EXTRAPOLATED TO PREDICT SERVICE LIFE UNDER NORMAL END-USE CONDITIONS. /AUTHOR/
