[MW:3637] Criteria of HIC testing CSR, CTR and CLR ratio.

Dear All,

         I have gone through the Nace MR 0175/ISO 15156, the HIC and SCC has to be carried out on the materials according to the standard.

Now I have gone through a project specification in which the client has specified clearly the requirement of HIC Testing, SSC testing on Pipes, Fittings, and Valves separately apart from the above stated standard requirement.

Another Project specification of different client do not specify these testing separately but they desire the materials to be according to NACE MR 0175/15156,

My question remains: Is HIC and SSC testing mandatory on all piping components for SOUR Services? if yes then please get me the code reference for it.

And also illustrate the CSR (Crack sensitive ratio) other two results like CLR and CSR.

The discussion on the chapter shall be appreciated.

Thanking You.

Bagesh.
