18、O 10675-1:2016ISO 10675-1:2016(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body inter
19、ested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
20、 Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO docume
21、nts should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible
22、 for identifying any or all such patent rights.

27、fections in butt welds of steel, nickel, titanium and their alloys detected by radiographic testing. If agreed, the acceptance levels can be applied to other types of welds or materials.The acceptance levels can be related to welding standards, application standards, specifications or codes. This do
28、cument assumes that the radiographic testing has been carried out in accordance with ISO 17636-1 and ISO 17636-2.When assessing whether a weld meets the requirements specified for a weld quality level, the sizes of imperfections permitted by standards are compared with the dimensions of indications
29、revealed by a radiograph made of the weld.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

36、sures may be applied in order to establish a basis for approximate quantification in accordance with the requirements of ISO 5817. This shall be specified in the adopted specification/procedure.5 Acceptance levelsThe acceptance levels of this document are basically valid for evaluation of imperfecti
37、ons which cannot be detected and evaluated by visual testing. Surface imperfections (such as undercut and excessive penetration, surface damage, weld spatter, etc.) which, due to object geometry, cannot be evaluated, but where the interpreter suspects the ISO 5817 quality levels are not fulfilled, s
38、hall be subject to more specific testing.The acceptance levels for indications are shown in Table 2 and Table 3. The types of imperfections are selected from ISO 5817 and defined in ISO 6520-1.The symbols used in Table 2 and Table 3 are the following: l length of indication, in millimetres; s nomina
39、l butt weld thickness, in millimetres; t base material thickness, in millimetres; L any 100 mm testing length; wpwidth of the weld, in millimetres; h width of indication, the width or height of surface imperfection, in millimetres; d diameter of pore, in millimetres; dAdiameter of pore envelope area
