14、ften produced for different applications but to similar requirements. The same requirements should, however, apply to identical parts produced in different workshops to ensure that work is carried out using the same criteria. The consistent application of this standard in one of the fundamental corn
15、erstones of a quality assurance system for use in the production of welded structures. There is a theoretical possibility of superimposed individual imperfections. In such a case the total summation of all permitted deviations should be restricted by the stipulated values for the different quality l
16、evels. However, the value of a single imperfection may exceed X h, e.g. for a single pore. This standard may be used in conjunction with standards for acceptance levels for non-destructive examinations. BS EN IS0 13919-1 : 1997 List of references See national foreword.
