IPX7 Waterproof Case-Independent Testing?

The OAD website has a link for application note that does not work, so I looked at what Gore says about their GAW 334 membrane...IP68...2m@60 minutes. Has the OAD team done any independent testing? If so what are the results?

As a scuba diver I take issue with the word "waterproof" as do many manufacturers of diving equipment. Suggest you use the word "water-resistant" and give the IP rating, if you know it. Even Gore doesn't use the term "waterproof".

I've fixed the links. The link to the standard case is for the original version that used a Porelle vent which is no longer manufactured. This will be updated in due course.

Can you post a photo of the white vent? Where did this case come from?

The vents should look like this: https://groupgets.com/products/replacement-acoustic-vent-for-audiomoth-case?_pos=4&_sid=0c71c2625&_ss=r

Yes. We call this a 'IPX7 Waterproof Case' and tested it to IPX7. Gore probably test their vent under ideal conditions and would be expected to get more performance. We tested with an AudioMoth and batteries inside the case. We don't expect that the case would actually be submerged during use. For actual use underwater, you should use the 'Underwater Case' which has been deployed up to 50m deep.

I was wanting to record a trickling stream with the device 6-8 inches underwater for just a minute. That shouldn't do any harm I would hope. You don't advise this?

You might get away with it but we wouldn’t advise intentionally submerging the case. You should use the underwater case or a hydrophone.

Additionally, my membrane on the new green case is white, but Gore says the 334 is black. Who puts on the membranes for OAD? Are they putting on the correct membrane?

Yes. Your case has a black GAW334 vent.
