BS EN ISO 17638:2016 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.This document does not specify acceptance levels of the indications. Further information on acceptance levels for indications may be found in ISO 23278 or in product or application standards.Cross References:ISO 3059ISO 9934-1:2015ISO 9934-2ISO 9934-3ISO 9712ISO 12707ISO 17635ISO 23278All current amendments available at time of purchase are included with the purchase of this document.
