ISO 20769-1:2018 is an international standard for non-destructive testing, specifically focusing on radiographic inspection of corrosion and deposits in pipes using X- and gamma rays. It outlines techniques, particularly tangential radiography, for detecting flaws like corrosion pitting, generalized corrosion, and erosion in pipes and similar cylindrical bodies. The standard is applicable to film and digital radiography, aiming for satisfactory and repeatable results.
