（3）Rounded discontinuities greater than a maximum size of E13, not to exceed 1/4 in [6 mm]. However, when E is greater than 2 in [50 mm], the maximum rounded indication may be 318 in [lo mm]. The minimum clearance of rounded discontinuities greater than or equal to 3/32 in [2.5 mm] to an acceptable elongated or rounded discontinuity or to an edge or end of an intersecting weld shall be three times the greatest dimension of the larger of the discontinuities being considered. 块状不连续性最大尺寸为E/3 （不超过 1/4 in. [6mm])；然而，当厚度大于2 in. [50mm]时，块状指示的最大尺寸可为3/8 in. [10mm]。块状不连续性的最小间距大于或等于3/32 in. [2.5mm]的这类不连续性，其到达另一个合格的条状或块状不连续性、或到达一条相交焊缝的边缘或端部的最小距离，必须为所考虑的较大不连续性的最大尺寸的3 倍。 (4)在一焊缝与另一焊缝或一自由边（即越过此边再无材料延伸存在）的交接处，可接受的不连续性应该符合图6.1中案例 I–IV 的限制。 （5） Isolated discontinuities such as a cluster of rounded indications, having a sum of their greatest dimensions exceeding the maximum size single discontinuity allowed in Figure 6.1. The minimum clearance to another cluster or an elongated or rounded discontinuity or to an edge or end of an intersecting weld shall be three times the greatest dimension of the larger of the discontinuities being considered. 孤立的，形似块状的一簇不连续性，其组成的每一不连续性的最大尺寸的总长超过图6.1所允许的单个最大尺寸。其到另外一簇、或到一条状或块状不连续性、或到一相交焊缝的边缘或端部的距离，必须为所考虑的不连续性中较大者最大尺寸的3 倍。 (6) The sum of individual discontinuities each having a greater dimension of less than 3132 in [2.5 mm] shall not exceed 2E13 or 318 in [I0 mm], whichever is less, in any linear 1 in [25 mm] of weld. This requirement is independent of (I), (2), and (3) above. 在任何25mm长的焊缝内，小于 2.5mm的不连续性中，每一较大尺寸的单个不连续性的总长严禁超过2E/3 或10mm（取其最小值）。本要求不受以上（1）、（2）和（3）要求的制约。 (7) In-line discontinuities, where the sum of the greatest dimensions exceeds E in any length of 6E. When the length of the weld being examined is less than 6E, the allowable sum of the greatest dimensions shall be proportionally less. 在任何6E 长度内，成一行的不连续性最大尺寸的总长超过E。当受检焊缝的长度小于6E时，容许的最大尺寸的总长必须按比例减少。 6.12.2 Discontinuity Acceptance Criteria for Cyclically Loaded Nontubular Connections. 周期载荷非管
