ISO 10675-1:2016 pdf download.Non-destructive testing of welds — Acceptance levels for radiographic testing — Part 1: Steel, nickel, titanium and their alloys
1 Scope
This document specifies acceptance levels for indications from imperfections 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 document 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 revealed by a radiograph made of the weld.

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 5817. This shall be specified in the adopted specification/procedure.
5 Acceptance levels
The acceptance levels of this document are basically valid for evaluation of imperfections 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, shall be subject to more specific testing. The acceptance levels for indications are shown in Ta ble 2 and Ta ble 3. The types of imperfections are selected from ISO 5817 and defined in ISO 6520-1.
