A new look at trends in non-destructive testing

Non-destructive testing (NDT) has been performed extensively for several decades. However, the NDT area is not in a static condition, as sophisticated equipment, improved procedures and new innovations keep development going on. Neither is the NDT field isolated from other fields, and this influences strongly the current situation, i.e.: The cost of electronics is decreasing and complex problems can now be solved; Safety requirements on products and components become more stringent; Quality requirements of the whole life span of a product or a component become more accentuated; Improved testing reliability is required; Quality assurance requirements must be imposed on NDT itself; New materials, e.g., fiber reinforced materials, and materials combinations, e.g., sandwich structures, will be used for special purposes; New production techniques, like glueing of metals, put new requirements on the NDT techniques
