This document specifies fundamental radiographic techniques which enable repeatable results to be obtained economically.This document applies to the X-ray radiographic examination of heated tool, electrofusion, extrusion and hot gas joints in plastics materials.It applies to joints in single wall pipes and plates with a range of thicknesses from 5 mm to 100 mm. It only applies to pipes containing air or other gases at the time of X-ray testing.This document does not specify acceptance levels of the indications.
