For the installation, inspection and maintenance, as well as servicing, there are regulations in various provincial laws, more details are given in the Ö-Norm B 2539.

The burden of proof is reversed, i.e. in the event of damage, it must be possible to prove on the basis of the test protocols and records that the hydrants were regularly maintained.
