EN 4533-004:2006

The original task headings in the Fibre Optic Harness Study were ‘Inspection and Fault Analysis’ and ‘Repair and Maintenance’. However, to create a more coherent and readable handbook these have been re-arranged in this part of EN 4533 to make two new topic headings, ‘Fault analysis and repair’ and ‘Scheduled maintenance and inspection’. The first deals with what to do when something goes wrong how to go from a fault notification to locating the fault, and finally, repairing it. The second covers the recommended procedures for upkeep and maintaining harness health over the lifetime of its installation. It is beneficial to read both sections together as many of the practices and techniques are applicable to both situations.Two supplemental sections consider designing a harness with repair and maintenance in mind and good practices when maintaining or repairing a harness.To keep the handbook to a reasonable size, other Harness Study reports are called up where more detail is required. This handbook does not contain sufficient information, for example, to be the sole reference for harness fault finding but it should provide adequate background for somebody working in that field.
