Hose fittings with clamp units - Part 7: Cam locking couplings; German and English version prEN 14420-7:2021
This document specifies the design, materials, dimensions and marking requirements for cam locking couplings that serve as the link between hoses and connections to transport liquids, solids and gases, except liquid gas and steam. The couplings are capable of operating the pressure range -0,8 bar to 16 bar working pressure in a working temperature range of -20 °C up to +65 °C. For all sizes of aluminium-cast-material couplings and for all couplings size DN 100 the pressure range is from -0,8 bar to 10 bar.
