Non-destructive testing of welds - Ultrasonic testing - Use of automated phased array technology

ISO 13588:2012 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 parent material are low-alloyed carbon steel.Where material-dependent ultrasonic parameters are specified in ISO 13588:2012, they are based on steels having an ultrasonic sound velocity of (5 920 ± 50) m/s for longitudinal waves, and (3 255 ± 30) m/s for transverse waves. It is necessary to take this fact into account when examining materials with a different velocity.ISO 13588:2012 provides guidance on the specific capabilities and limitations of 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.ISO 13588:2012 specifies four testing levels, each corresponding to a different probability of detection of imperfections.ISO 13588:2012 permits assessment of indications for acceptance purposes based on either amplitude (equivalent reflector size) and length or height and length.ISO 13588:2012 does not include acceptance levels for discontinuities.ISO 13588:2012 is not applicable: for coarse-grained metals and austenitic welds; for automated testing of welds during the production of steel products covered by ISO 10893-8, ISO 10893-11, and ISO 3183.

Non-destructive testing of welds - Ultrasonic testing - Use of automated phased array technology

ISO 13588:2012 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 parent material are low-alloyed carbon steel.

Where material-dependent ultrasonic parameters are specified in ISO 13588:2012, they are based on steels having an ultrasonic sound velocity of (5 920 ± 50) m/s for longitudinal waves, and (3 255 ± 30) m/s for transverse waves. It is necessary to take this fact into account when examining materials with a different velocity.

ISO 13588:2012 provides guidance on the specific capabilities and limitations of 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.

ISO 13588:2012 specifies four testing levels, each corresponding to a different probability of detection of imperfections.

ISO 13588:2012 permits assessment of indications for acceptance purposes based on either amplitude (equivalent reflector size) and length or height and length.

ISO 13588:2012 does not include acceptance levels for discontinuities.

ISO 13588:2012 is not applicable: for coarse-grained metals and austenitic welds; for automated testing of welds during the production of steel products covered by ISO 10893-8, ISO 10893-11, and ISO 3183.

Non-destructive testing of welds - Ultrasonic testing - Use of automated phased array technology

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.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
