ISO 10675-2:2017 pdf download.Non-destructive testing of welds — Acceptance levels for radiographic testing
1 Scope
This document specifies acceptance levels for indications from imperfections in aluminium butt welds 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 document assumes that the radiographic testing has been carried out in accordance with ISO 17636-1 for RT-F (F =film) or ISO 17636-2 for RT-S (S = radioscopy) and RT-D (D = digital detectors).
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 revealed by a radiograph made of the weld.

4 Radiographic technique
Depending on the weld quality level, radiographic technique A or B in accordance with ISO 17636-1 shall be used for RT F as shown in Table 1 and radiographic technique A or B in accordance with ISO 17636-2 shall be used for RT-S or RT-D as shown in Table 2.
5 General
Welded joints should be visually tested in accordance with ISO 17637 and evaluated before radiographic testing. The acceptance levels in this document are basically valid for evaluation of imperfections which cannot be detected and evaluated by visual testing (see Table 3). Surface imperfections (see Table 4: 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 10042 quality levels are not fulfilled, shall be subject to more specific testing. When quantification of undercut and/or excessive penetration by radiographic testing is required, specific procedures using test exposures may be applied in order to establish a basis for approximate quantification in accordance with the requirements of ISO 10042. This shall be specified.
