GB/T 28799.2 - 2012 PE-RT pipes for focused hot and cold water. It specifies the terminology of pipes, and specifies the classification and marking. The technical requirements cover Appearance, such as color uniformity; dimensional deviation, including outer diameter and wall thickness; as well as physical and mechanical properties, such as hydrostatic strength, longitudinal retraction rate, etc. The standard gives detailed test methods for testing various performances, such as equipment, pressure and time setting for hydrostatic strength testing. At the same time, it specifies inspection rules. The standard is a check for the production of PE-RT pipes, providing a basis for the selection of materials for building hot and cold water pipeline projects, ensuring the stable operation of pipeline systems under different working conditions, ensuring water supply safety and pipeline service life.
