May I ask whether the spray rust removal grade Sa2 1/2 specified in GB/T 8923.1-2011 \"Surface treatment of steel substrates prior to coating application – Visual assessment of surface cleanliness – Part 1: Rust grades and treatment grades for uncoated steel surfaces and steel surfaces from which the existing coating has been completely removed\" can be written as Sa2.5? It’s best to give reasons for both yes and no.

Sure, for a long time we’ve written our drawings this way, and no one has raised any objections

Sure, both sa2.5 and 2 and a half have been seen on the drawings

There’s no difference; Sa2.5 is seen more often
