m side. The sensitivity obtained with IQI on the source side shall not be less than the values shown in

Fig. 6 of this specification. The sensitivity limit may be considered to have been reached when the outline of the

IQI, its identification number and the wire of the required dia meter show up clearly on the radiographs. The COMPANY

may authorise use of types of IQI other than thos planned, provided that they conform with recognised standards and only

if the CON TRACTOR is able to demonstrate that the minimum sensitivity level required is obtained. For this , ecified and the CONTRACTOR' to show up the identification number and other det ails of the proposed IQI, which must be visible in the test radiograph. 7.0 FILM IDENTIFICATION MARKERS All films shall be clearly identified by lead numbers, letter , and/ or markers. The image of the markers shall appear on the films, without interfering with the interpretation. These markers positions shall also be marked on the part to be radiographed and shall be maintained during radiography. 8.0 PROTECTION AND CARE OF FILM 8.1 All unexposed films shall protected and stored properly as per the requirements of API 1 standard and ASTM 9. 8 . 2 , light, dust and moisture. Sufficient shielding shall be supplied to prevent exp osure of film to damaging radiation prior to and following the use of the film for radiog raphic exposure. 9.0 RE-RADIOGRAPHY 9.1 The weld joints shall be re-radiographed in case of unsatisfactory quality of the radiographs, at the expe nse of the CONTRACTOR. 9.2 All the repaired weld joints shall be re-radiographed at extra cost to the COMPANY in the same manner as that followed for the original welds. In addition, the repaired weld area shall be identified with the original identification number plus the letter `' to indicate the repair. 9.3 Whe
