I am fairly aware of placing a piece of cloth under increasing water pressure until it leaks. But son has just bought a tent and in the sales blurb says it is tested to 3,000 hydrohead now I have no idea what units that is or if 3,000 is good bad or indifferent.
Can anyone shed any light.

Could it be 3000mbar
Sounds like the water equiv. of music power for amplifiers.

Or 3000mmHg ?
Right idea but surely that would have been hydrargyrum-head?
Hydrohead would be 3000mm of water. A lot more practical for measuring tent fabric.

That would be 11,000 then, shirly
Might be logarithmic.

Probably mistranslated from the furrin'.
I know about hydrostatic testing. What I want to know is what units.
3,000 Hydrohead is meaningless (and yes that is all it says not a hydrohead of 3,000 units 0r 3,00 units hydrohead or anything like that merely 3,000 hydrohead).
It says in the linky that the units are mm of water.
Isn't Hydrohead a Marvel superhero?
No, they're air-heads that like wet, wet, wet
