If any rejectable flaws are found, 100 percent of the weld <br /> 41 within the specified limits shall be inspected. The largest column cross section diameter <br /> 42 for tapered column jackets shall constitute one column jacket diameter. <br /> 43 <br /> 44 6-03.3(25)A4 Magnetic Particle Inspection <br /> 45 Items number 3 and 4 are revised to read: <br /> 46 <br /> 47 3. Complete penetration groove welds on plates %6-inch or thinner (excluding steel <br /> 48 column jackets) shall be 100 percent tested by the magnetic particle method. <br /> 49 Testing shall apply to both sides of the weld, if backing plate is not used. The ends <br /> 50 of each complete penetration groove weld at plate edges shall be tested by the <br /> 51 magnetic particle method. <br /> 52 <br /> I <br /> AMENDMENTS TO THE 2014 STANDARD SPECIFICATIONS BOOK <br /> Revised: 8/3/15 <br />
