Venkat,
Which IQI? ASTM, DIN(ISO), FE EN? all differes and depends upon thickness of the object being radiographed...Diameter is not a concern.

Dear Venkat
Applicable test standards: ASME Sect. V Art.2 for procedure, Pipe 6” SCH80, norm. Thk 11.0. Exp. Technical: DWSI, IQI on film side, essential wire number 6 (dia. 0.25) So you can select ASTM 1A 6 or ASTM 1B 11.
Dear Venkat
Thickness of weld does not include any reinforcement as ASME specified.
This for sample, 6" sch 80 is 0.432 in (10.973 mm) if Low pressure it would be 13.973mm thickness + reinforcement included, use ASTM 1B or 10 FE EN
Make sure ASTM or EN or what kind IQI mentioned in RT procedure.
