The time where the promise was to replace a product if it does not work seems to have passed; what is more impor­ tant now is not so much a reduction in what is going wrong but an increase of what is going right the first time (Feigenbaum 1990). This new trend is sometimes referred to as total quality. Among the many advantages ofthis zero-defect manufacturing policy, we can enumerate (Laurin 1990): superior marketability of wholly de­ pendable products, enormous gain in productivity, elimination of waste­ ful cost in replacing poor quality work and retrofitting rejected products from the field. Although total quality is a relatively new and attractive concept for mass products such as cars, consumer electronics and per­ sonal computers, in many fields, mainly aerospace and military, it has been the rule for years because of security reasons. 606 $aMechanics, Applied 606 $aElectronics 606 $aMaterials$xAnalysis 606 $aCondensed matter 606 $aEngineering Mechanics 606 $aElectronics and Microelectronics, Instrumentation 606 $aCharacterization and Analytical Technique 606 $aCondensed Matter Physics 615 0$aMechanics, Applied. 615 0$aElectronics. 615 0$aMaterials$xAnalysis. 615 0$aCondensed matter. 615 14$aEngineering Mechanics. 615 24$aElectronics and Microelectronics, Instrumentation. 615 24$aCharacterization and Analytical Technique. 615 24$aCondensed Matter Physics. 676 $a620.1 700 $aMaldague$b Xavier P.V$4aut$4http://id.loc.gov/vocabulary/relators/aut$01124795 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910960442403321 996 $aNondestructive Evaluation of Materials by Infrared Thermography$94431815 997 $aUNINA
