This part of ISO 7005 for a Single System of flanges specifies requirements
for circular topper alloy and composite flanges in
the following nominal pressure ratings:
Series l* Series 2*
ISO PNIO
ISO PN16
ISO PN20
ISO PN50
ISO PN6
ISO PN25
ISO PN40
Attention is drawn to the need to refer to the pressure/
temperature (p/T) ratings in tables 10, lOa), IOb) and 10~)
for the maximum permissible working pressures and
temperatures, particularly for ISO PN20 and ISO PN50 flanges
and for ISO PN6, ISO PNIO, ISO PN16 and ISO PN25 flanges
attached by soft solder or silver brazing.
This part of ISO 7005 specifies the types of flanges and their
