Which statement about field testing symbol placement is correct?

• A. It is attached to the tail of the reference line.
• B. It is attached to the reference line.
• C. It is attached to the all around symbol.
• D. It is attached to the arrow line.

Answer: (C)

Field work around a joint is shown by placing the field indication on the all-around symbol. The all-around symbol signals that the weld extends all the way around the joint, such as a circumferential weld on a pipe. Attaching the field requirement to that symbol communicates two things at once: the weld is to be performed in the field, and it goes around the entire circumference. Placing the field indication on the reference line, its tail, or the arrow line would not clearly convey the all-around, field-welding requirement, so they don’t fit as correctly as attaching it to the all-around symbol.
