Life cycle costing is relevant at portfolio/estate management

IEC 60050(426):1990

A valve leak rate less than the nominal leak rate specified by the manufacturer during and after the operation enables the specification of such valve operating conditions as operating pressure range

The specification is applicable to situations where the electric fence is designed to provide both a deterrent effect as well as a physical security barrier
