NOTES:

(1) See paragraph 4.2

(2) RT = Radiographic Examination, UT = Ultrasonic Examination, MT = Magnetic Particle Examination, PT = Liquid Penetrant Exam

(3) 2% if 30 mm (1-3/16 in.) and same weld procedure specification as longitudinal, for steel of P-No. 1 Gr 1 and P-No. 8 Gr 1

(4) 10% if 30 mm (1-3/16 in.), 0% if 30 mm (1-3/16 in.)

(5) Percentage in the table refers to the aggregate weld length of all the nozzles, see paragraph 7.4.3.5(b).

(6) RT or UT is not required for weld thicknesses 16 mm (5/8 in.)

(7) 10% for steel of P-No. 8 Gr 2, P-No. 9A Gr 1, P-No. 9B Gr 1, P-No. 11A Gr 1, P-No. 11A Gr 2, P-No. 10H Gr 1

(8) (Currently not used.)

(9) For limitations of application see paragraph 4.2.

(10) The percentage of surface examination refers to the percentage of length of the welds both on the inside and the outside.

(11) RT and UT are volumetric examination methods, and MT and PT are surface examination methods. Both volumetric and surface ex

be applied the extent shown.

(12) NA means "not applicable". All Examination Groups require 100% visual examination to the maximum extent possible.(13) See paragraph 7.4.8.1 for detailed examination requirements.

(14) The percentage of examination refers only to the repair weld and the original examination methods, see paragraph 6.2.7.3.

(15) RT is applicable only to Type 1, full penetration welds.

(16) The term a as defined in Figure 7.16.

(17) The term a as defined in Figure 7.17.

(18) For SAW welds in 21/4 Cr1Mo1/4V vessels, ultrasonic examination in accordance with 7.5.4.1(e) is required.
