and at the least density expected of the area of interest (diagnostic film length).
In addition, for weld inspection, the wires shall be placed across and
perpendicular to the weld axis. Where placement of IQI on the source side is
impracticable, it may be placed on the film side provided the following condition
is met:-
a) Set up a test piece of the same dimensions as the production weld to be
radiographed on which IQIs can be placed on both source and film sides.
b) Place a lead letter 'F' next to the film side IQI.
c) Take a test radiograph using the same radiographic technique that will be
used on the production weld.

technique, one IQI on the source side shall be used.

iii. Multiple Exposure

a) When the length of a film to be interpreted (diagnostic film length) is eight

inches and longer, two IQIs placed at each end of the diagnostic film
length shall be used.
b) When the diagnostic film length is less than eight inches, one IQI placed
at one end of the diagnostic film length shall be used.

2.9 DIAGNOSTIC FILM LENGTH (DFL)

2.9.1 In order to meet the density requirements and to allow for the fall-off in flaw sensitivity
towards the ends of the radiograph due to an increase in penetrated thickness and to
geometric effects, the Diagnostic Film Length (DFL) shall be limited to thickness not more than
110% of the penetrated/thickness at the center of the radiograph.

2.10 RADIOGRAPHIC TESTING TECHNIQUES

2.10.1 In the procedure submitted to the Owner, the Contractor shall formulate and incorporate
detailed radiographic techniques, including sketches that are to be used in the inspection.
Standard test radiographs shall be produced based on the parameters of the approved
techniques.

2.10.2 Single Wall Exposure Technique

In this technique, the radiation passes through only one wall of the object. An adequate
number of exposures (multiple) shall be made to ensure that the required coverage has been
obtained.

2.10.3 Double Wall Exposure Technique

When it is not practical to use a Single Wall Exposure Technique, the following shall be used:-

i. Single-wall Viewing

a) In this technique, the radiation passes through two walls, but only the
material or weld near the film side is viewed. An adequate number of
exposures shall be made to ensure that the required coverage has been
obtained. For complete coverage of a circumferential weld or materials,
a minimum of three exposures at 120 degrees to each other shall be
made.

ii. Double-wall Viewing

 PTS 15.30.01
RADIOGRAPHIC TESTING October 2014
Page 14 of 22

a) This technique applies to materials or welds having 89 mm (3 1/2 inches)

or less in outside diameter.
b) In this technique, the radiation passes through two walls and the material
or weld in both walls is viewed on the same radiograph. For this
technique, only a source side IQI shall be used.
c) For welds, the radiation beam may be offset from the plane of the weld
at an angle sufficient to separate the images of the source side and film
side portions of the weld so that there is no overlap of areas to be
interpreted. For complete coverage, a minimum of two exposures at 90
degrees to each other shall be made for each joint.
d) As an alternative, the weld may be radiographed with the radiation beam
positioned so that the images of both walls are superimposed. For
complete coverage a minimum of three exposures at either 60 or 120
degrees to each other shall be made for each joint. This technique shall
be used for thick walled pipe welds of diameters equal to or less than 25.4
mm (1 inch).

iii. Composite viewing of multiple films exposure in not permitted unless written
approval by the Owner has been obtained.

2.11 QUALITY OF RADIOGRAPHS

2.11.1 All radiographs shall be free from mechanical, chemical or other blemishes to ensure that they
shall not mask or be confused with the image of any flaw in the area of interest within the
produced radiograph. Such blemishes, include, but are not limited to:

i. Fog

ii. Processing defects such as streaks, water marks or chemical stains

iii. Scratches, finger marks, crimps, dirtiness, static marks, smudges or tears

iv. False indications due to defective screens or internal faults

v. Interference on areas of interest by lead markers

radiating source or focal spot in
the plane perpendicular to the distance D from the
weld or object being radiographed in
D = source to weld or object distance in inches
d = source side of weld or object to the film distance in
inches.
