S and B standard for MS Plates

I want to know the Standard for surface preparation through sand blasting of mild steel plates as per IS 2062 and the detailed specification of sand to be used.

I would like to clarify that S A 2 1/2 standard is for sand blasting ( a surface preparation method) for cast iron items.

Similarly, I want to know about the standard for sand blasting of Mild steel shell plates of fabricated Oil storage tanks and the type of sand to be used in this process.

Hi, Mr. Rao. "Sa2.5" is a Swedish Institute for Standards designation for "near white" blasted finish -- approximately equivalent to NACE No. 2/SSPC-SP10, and ISO 8501-1 WA.2.5

Please see thread 12526 for a more complete explanation.
