5.1 Security measures

Local or national or international safety precautions when using ionising radiation should be strictly

applied.

WARNING — Exposure of any part of the human body to X-rays can be highly injurious to health.

Wherever X-ray equipment is in use, appropriate legal requirements should be applied.

5.2 Surface preparation and stage of manufacture

Prior to radiography the joint shall be cleaned to remove all traces of dirt etc. from the component surface,

which might later cause difficulty in detecting defects.

In the case of heated tool butt welded pipes, the external weld bead shall be removed prior to

radiography.
5.3 Location of the weld in the radiograph

Where the weld is not likely to be clearly visible on the radiograph, high-density markers (e.g. lead) shall

be placed on either side of the weld before testing.
5.4 Identification of radiographs

Symbols (normally lead markers) shall be affixed to each section of the object being radiographed. The

images of these symbols shall appear in the radiograph outside the region of interest and shall ensure

unambiguous identification of the section.
