BS EN ISO 10863:2020

What is ISO 10863 - Non-destructive testing of welds about? 

ISO 10863 specifies the application of the time-of-flight diffraction (TOFD) technique to the semi- or fully automated ultrasonic testing of fusion-welded joints in metallic materials of minimum thickness 6 mm. 

ISO 10863 is applicable to full penetration welded joints of simple geometry in plates, pipes, and vessels, where both the weld and the parent material are low-alloyed carbon steel. Where specified and appropriate, TOFD can also be used on other types of materials that exhibit low ultrasonic attenuation. 

Where material-dependent ultrasonic parameters are specified in this document, they are based on steels having a 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 testing materials with a different velocity. 

ISO 10863 specifies four testing levels (A, B, C, D) in accordance with ISO 17635 and corresponding to an increasing level of testing reliability. Guidance on the selection of testing levels is provided. 

Note: ISO 10863 does not include acceptance levels for discontinuities. 

Who is ISO 10863 - Non-destructive testing of welds for? 

ISO 10863 on non-destructive testing of welds is applicable to 

• Construction, automotive, mechanical Industries 
• Manufacturers of pressure vessels 
• Sheet metal and boiler manufacturers 
• Manufacturers of aircraft & aerospace 
• Shipbuilding industry 
• Aerospace industry 

Why should you use ISO 10863 - Non-destructive testing of welds? 

Ultrasonic is a non-destructive method to test any defects or cracks in welds. This test uses sound waves. 

ISO 10863 provides guidance on the specific capabilities and limitations of time-of-flight diffraction (TOFD) for the detection, location, sizing, and characterization of discontinuities in fusion-welded joints which provides high quality and efficient welded joints. 

Obtain guidelines of ISO 10863 for Time-of-flight diffraction (TOFD) which can be used as a stand-alone method or in combination with other non-destructive testing (NDT) methods or techniques, for manufacturing inspection, and for in-service inspection. 

ISO 10863 can be used in the assessment of time-of-flight diffraction (TOFD) indications for acceptance purposes. This assessment is based on the evaluation of transmitted, reflected, and diffracted ultrasonic signals within a generated TOFD image.
