Is ASTM B-117 done pre-assembly or post?

I have a client looking for a blind rivet assembly (aluminum body rivet with a zinc dichromate plated mandrel) and is asking for this item to withstand 96 hr salt spray in accordance with ASTM B117. My question is regarding the format of this test and wether it is done pre or post installation?

ASTM B117 describes how to build and operate a salt spray chamber. It doesn't talk about performance specifications for a particular part. This is something you will have to resolve with your client, but it doesn't make much sense to me to test before assembly--especially because the riveting process will stretch the coating material and reduce its protective value.
