No code specified these values.
It is specified in specification.
Generally for SS , it is less than 50ppm

Dear Nandush,

Code dose not specified PH value for Hydro Test.
Pl. Ask to client and Testing according.

Yes, code may not required, but project specification may require in the test package. I hope that everyone check in the specification also.

Dear 

PH & PPM 

1 . C. S - less then 250ppm or specified by client spec. 
2. S.S- 50 ppm Or specified by client spec. 
3. PH - 07 natural water 6.5-7.5 best

Lesser PH value more acidic below 06 Or equivalent 06 for stainless steels, it's better to refer client specifications for PH value
