ISO 17637:2003(E) iv © ISO 2003 — All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

INTERNATIONAL STANDARD ISO 17637:2003(E) © ISO 2003 — All rights reserved 1 Non-destructive testing of welds — Visual testing of fusion-welded joints 1 Scope This International Standard covers the visual testing of fusion welds in metallic materials. It may also be applied to visual testing of the joint prior to welding. 2 Test conditions and equipment The illuminance at the surface shall be a minimum of 350 lx. However, 500 lx is recommended. For direct inspection, the access shall be sufficient to place the eye within 600 mm of the surface to be examined and at an angle not less than 30° (see Figure 1).
a Range Figure 1 — Access for testing Remote inspection using mirrors, boroscopes, fibre optic cables or cameras shall be considered when the access for testing in accordance with Figure 1 is not possible or when specified by an application standard. An additional light source can be used to increase the contrast and relief between imperfections and the background. Where the result of visual testing is inconclusive, the visual test should be supplemented by other non-destructive testing methods for surface inspections. Examples of equipment used for visual testing are given in Annex A. 3 Personnel qualification Visual testing of welds and the evaluation of results for final acceptance shall be performed by qualified and capable personnel. It is recommended that personnel be qualified in accordance with ISO 9712 or an equivalent standard at an appropriate level in the relevant industry sector. SIST EN ISO 17637:2011

However, this should be determined in advance, e.g., by reference to an application or product standard. The examiner shall have access to the necessary inspection and production documentation required. Any visual testing prior to, during or after completion of the weld should be carried out while physical access is still possible. This may include the visual testing of surface treatments. 4.2 Visual testing of joint preparation When visual testing is required prior to welding, the joint shall be examined to
