BS EN ISO 17638:2016,the title is Non-destructive testing of welds—Magnetic particle testing.
Here I would like to say that BS EN ISO 17638:2016 replaces BS EN ISO 17638:2009. You need to understand this.
This document specifies techniques for detection of surface imperfections in welds in ferromagnetic materials, including the heat affected zones, by means of magnetic particle testing. The techniques are suitable for most welding processes and joint configurations. Variations in the basic techniques that will provide a higher or lower test sensitivity are described in Annex A.
