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



2005

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 [affil. link to spec at Techstreet] . 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 specsifications 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.
