Abstract

Introduction: During the past few years radioscopy has established itself in many fields that demand instant evaluation and a high degree of automation, as is the case in serial inspection. Furthermore, user experience has clearly shown that inspection costs can be considerably reduced by this technique.

It is particularly in the serial inspection of castings, that radioscopy constitutes stateof-the-art when applied in conjunction with systems for image intensification, digital image processing and automatic image evaluation. For the examination of welds, however, standardization is still non-existent, thus rendering more difficult the application of this inspection technique.As a consequence the approval procedures of the respective supervisory or certification boards are often complicated and of necessity set up for each individual case.

For some years now, standards for radioscopic applications have been in the drafting stage. This paper will discuss the present state of the preparations that the ad hoc working group "Radioscopy" of IIW, CEN and ISO is involved in.
