Standards Development
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. It is recommended that before allocating new hose connections. member bodies should consults tables 2 to 4 and select, if possible, those connections which have been adopted by the greatest number of countries. The listed hose connections are also in common use in countries not known to have issued a standard for hose connections, and this information is also given where available to the Committee. This use may be only partial in those countries.
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, reference should be made to the corresponding national standard or national industry specification.
