Nominally a 13Cr that will show rusting and pits in a day.

A2 is a martensitic tool steel, not a "stainless steel". It will rust almost instantaneously (less than 5 hours) when exposed to salt spray unless it has some type of corrosion resistant coating on it. You will need a different alloy or some type of coating if there is a requirement for significant hours of exposure to ASTM B 117 with no red rust.

A2 stainless steel is austenitic stainless steel, like 304 &304L

Yes, It's follow ISO 3506.

Properly produced A2 fasteners shouldn't produce visible red rust for a LONG time during a neutral salt spray test. If it does, then it is due to iron pickup from forming/cutting/etc. This test method isn't suited for testing stainless steel.
Regarding standards, I would review corrosion standards like those from ASTM and ISO:

As CoryPad stated, salt spray testing is not really used to test stainless steel fasteners like ISO 3506 A2 or A4. However, here is one example of some testing by a fastener manufacturer showing the corrosion resistance of Type 304 (ISO 3506 A2) after salt spray testing:
