For all sizes of aluminium cast material couplings and for all couplings of size DN 100, the pressure range is from −0,8 bar to 10 bar in the working temperature range from −20 °C to +65 °C. All other couplings according to this document are capable of operating within the pressure range from 0,8 bar1 to 16 bar in the working temperature range from −20 °C to +65 °C.

Purpose

The following required changes have been indentified in EN 14420-7:

- Figure 3 provides a wrong entrie,

- Figure 6 provides an entry without further explenation.
