标准范围

This document specifies the application of the phased array technology for the semi- or fully automated 
ultrasonic testing of fusion-welded joints in metallic materials of minimum thickness 6 mm. It applies 
to full penetration welded joints of simple geometry in plates, pipes, and vessels, where both the weld 
and the parent material are low-alloy and/or fine grained steel. For the testing of welds in other steel 
materials this document gives guidance. For coarse-grained or austenitic steels, ISO 22825 applies in 
addition to this document.
This document provides guidance on the specific capabilities and limitations of the phased array 
technology for the detection, location, sizing and characterization of discontinuities in fusion-welded 
joints. Phased array technology can be used as a stand-alone technology or in combination with other 
non-destructive testing (NDT) methods or techniques, for manufacturing inspection, pre-service and 
for in-service inspection.
This document specifies four testing levels, each corresponding to a different probability of detection of 
imperfections.
This document permits assessment of discontinuities for acceptance purposes based either on 
amplitude (equivalent reflector size) and length, or on height and length.
This document does not include acceptance levels for discontinuities.
This document is not applicable for automated testing of welds during the production of steel products 
covered by ISO 10893-8, ISO 10893-11 and ISO 3183.
