Gas welding equipment -- Hose connections for equipment for welding, cutting and allied processes -- Listing of connections which are either standardised or in common use
ISO/TR 28821:2012 lists the hose connections for equipment for welding, cutting and allied processes which are standardised within countries of ISO member bodies. Its purpose is to prevent further proliferation of hose connections in countries or fields of applications where such connections have not been standardised.
ISO/TR 28821:2012 only provides details of the thread type and size applying to that connection.
