A complete traceability system can be built up from the following elements: fusion-jointing equipment data fusion-jointing equipment operator data, site data (geographical location), data on fittings and pipes and fusion-jointing parameters, installation dates and assembly procedures. fusion-jointing equipment, fusion-jointing equipment operators and fusion-jointing protocols. It is widely pipelines, relating to compatibility, for instance. Such systems may be subject to patent rights. system. Care is necessary when determining which data are to be downloaded into the traceability system the amount of data will strongly influence the performance of the database when it is used later. ed without license from IHS Not for Resale CopyrightintemationalOrganizatonfor Standardization Noroctiorntwoking emitedwihou licne frmH Not for Resale INTERNATIONALSTANDARD IS
