International Electrotechnical Commission (IEC) Specs

The majority of International Electrotechnical Commission (IEC) standards
for control valves, several of which are based on ISA standards. have been
re-published as EN standards and utilize an EN prefix. The IEC encourages
national committees to adopt them and to withdraw any corresponding
national standards. IEC standards are increasingly being applied by
manufacturers and purchasers. Below is a list of IEC industrial-process control
valve standards (60534 series).
