Annex A (informative) Diver-welder or welding operator test
        certificate for hyperbaric dry welding
Annex B (informative) Job Knowledge

This standard applies to welding processes where the skill of the diver-welder or welding operator has a significantinfluence on weld quality.This standard specifies essential requirements, ranges of approval, test conditions, acceptance requirements andcertification for the approval testing of diver-welder or welding operator performance for the welding of steelsunderwater in a hyperbaric dry environment. The recommended format for the certificate of approval testing is givenin Annex A.During the approval test the diver-welder or welding operator should be required to show adequate practicalexperience and job knowledge (test non mandatory) of the welding processes, materials and safety requirements forwhich he is to be approved, information on these aspects is given in Annex B.This standard is applicable when the diver-welder s or welding operator s approval testing is required by thepurchaser, by inspection authorities or by other organisations.The welding processes referred to in this standard include fusion welding processes which are designated as manualor partly mechanized welding for diver-welders and fully mechanized or automatic welding for operators (see 5.2).All new approvals are in accordance with this standard from the date of this issue.However, this standard does not invalidate previous diver-welder or welding operator approvals made to formernational standards or specifications, providing the intent of the technical requirements is satisfied and the previousapprovals are relevant to the application and production work on which they are to be employed.Also, where additional tests should be carried out to make the approval technically equivalent it is only necessaryto do the additional tests on a test piece which should be made in accordance with this standard.
