Abstract
Ïã¸ÛÁùºÏ²Ê¿ª½± 12176-4:2003 specifies an encoding system for data on components, assembly methods and jointing operations for polyethylene (PE) piping systems for gas supply, for use in a traceability system.
Reading of the codes can be carried out using alphanumeric or numeric data-recognition systems such as bar-code, magnetic-stripe card or microchip card readers.
This part of Ïã¸ÛÁùºÏ²Ê¿ª½± 12176 is applicable to PE pipes, fittings and valves conforming to Ïã¸ÛÁùºÏ²Ê¿ª½± standards for gas supply piping systems and also to the assembly operation utilizing methods such as fusion using a heating tool (butt, socket and saddle fusion), electrofusion (socket and saddle fusion), induction fusion and mechanical jointing.
