Acropolis Family IP Testing: Explorator chirper #2 (Improved Failure)
To provide adequate protection from liquid ingress under expected installation scenarios while installed right-side-up, Acropolis artefacts should demonstrate ingress protection ratings of at least IPx3 to ensure they are ``protected against drops of rainwater at up to 60 degrees from the vertical''. While this will protect artefacts within Hyper-Soundwalk Series pop-up exhibitions, to provide additional security and increase installation options, the optimal Acropolis family liquid ingress protection rating is IPx4. Therefore, the minimum enclosure IP rating for Acropolis family artefacts is IP33, while the optimal rating is IP54.
This footage shows controlled liquid ingress tests that were conducted to supplement the in-situ data. For the test, Explorator Chirper was `installed' in a shower-basin suspended in the air using typical exhibition hardware. Then, to simulate torrential rain, the shower head was directed at the enclosures from 2 metres at a 45 degree angle. The enclosures were subjected to a water flow of 6.98 litres per second for at least ten minutes before examining the enclosures for liquid ingress.
In this second test, the enclosure top-cap still proved troublesome and did result in the ingress of unwanted water during the test. The results of this test has established a limit of the artefact’s protection from water during exhibition. Further improvements to the enclosure design have been made and test footage for the improved design will be posted soon =).
