How to analyze salt spray solution

How to analyze salt spray solutions? Is there any specs with these details to follow? I didn't find on ASTM ASTM B117 .

Thanks!

If you read the fine print, Note 11 in the std. I have B-117 -90. It states that a solution having a SG of 1.0255-1.0400 @ 25°C will meet the concentration std. There is also another method, titrating with AgNO3 in the same note.

In the current version of B117 (97), paragraph 8 describes the solution relative to pH, specific gravity. The important fact to remember is that these measurements apply to the collected solution. You can adjust the mixture as needed (but within reason of course) in order to achieve the proper pH.
