ASME Sec.VIII Div.1 Appendix 4, 2015 Ed.

[R.Andreucci]

Dear Sirs.

I have a doubt about aligned rounded indications observed by Radiographic Examination.

Regarding to Fig.4-1 of ASME Sec.VIII Div.1 App. 4, in case of aligned rounded relevant indications are aggregated in a length greater than 12.t , may be possible to accept ?

Example:

- Thickness of base metal: 6 mm

- Sum of lengths of all aligned rounded indications: 5,4 mm

- Length of aggregate aligned rounded indications: 80 mm  (> 12.t)

Are they accepted ?

Thank you for you attention.
