<p>This standard specifies essential requirements, ranges of approval, test conditions, acceptance requirements and</p>
<p>certification for the approval testing of welder performance for the welding of nickel.</p>
<p>This standard applies to the approval testing of welders for the fusion welding of nickel.</p>
<p>This standard is intended to provide the basis for the mutual recognition by examining bodies for approval relating to</p>
<p>welders' competence in the various fields of application. Tests will be carried out in accordance with this standard unless</p>
<p>more severe tests are specified by the relevant application standard when these are applied.</p>
<p>During the approval test the welder should be required to show adequate practical experience and job knowledge (test</p>
<p>non mandatory) of the welding processes, materials and safety requirements for which he is to be approved; information</p>
<p>on these aspects is given in Annex A.</p>
<p>This standard is applicable when the welder's approval testing is required by the purchaser, by inspection authorities or</p>
<p>by other organizations.</p>
<p>The welding processes referred to in this standard include those fusion welding processes which are designated as</p>
<p>manual or partly mechanized welding. It does not cover fully mechanized and automatic processes (see 5.2).</p>
<p>This standard covers approval testing of welders for work on semi-finished and finished products made from wrought,</p>
<p>forged or cast material types listed in 5.4.</p>
<p>The certificate of approval testing is issued under the sole responsibility of the examiner or examining body.</p>
