Hi, T.N.C.. This is a Swedish Institute for Standards designation for "near white" blasted finish -- approximately equivalent to SSPC-SP 10, NACE No. 2, and ISO 8501 WA.2.5

I believe it's actually "Sa.2.5", but I don't know is "Sa" is an abbreviation or acronym in Swedish.

Please see letter 12526 for a more complete explanation.
