1   Scope This Technical Report 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. This Technical Report only provides details of the thread type and size applying to that connection. For a more complete description of a hose connection and further applicable requirements and limitations, refer to the corresponding national standard or national industry specification.
