Caisson test
Thread Content
Everyone, I heard a new term today – what is a pressure vessel caisson test? Are there any reference materials or **standards? Thank you.
Mm! After all these years, it’s really a new term. Is it the underwater airtightness test?
Caisson test? I’ve heard of it for the first time; could someone give me some information?
I estimate: a method of observation in container pressure and airtightness tests. After inflating the container, submerge it in a large pool of clean water. If there is a leak in the container, a series of bubbles or small bubbles will form in the water, making it easier to observe the situation. The container should be left there for X hours to monitor changes in the pressure gauge reading; at the same time, any abnormal noises or deformations should also be observed. However, attention should be paid to the changes in water temperature (ambient temperature) during the X hours of submersion, as the surface values may fluctuate.
Thank you all for the discussions. As mfka said, I’m not sure what the official standard language is, nor which standard should be used as a reference for testing I simply can’t find it using a search engine.
