Anotace textu normy ASTM F2623-25 :

This specification establishes the basic requirements and corresponding test methods for polyethylene of raised temperature (PE-RT) SDR 9 tubing that is outside diameter controlled, and pressure rated for water at specific temperatures. The tubing produced under this specification shall be permitted for use in general fluid transport, including hydronics and irrigations systems. The plastic used to make the tubing shall be virgin plastic or reworked plastic and shall have Plastics Pipe Institute (PPI) long-term hydrostatic design stress and pressure ratings as the specified temperatures. When evaluated by the test procedures provided herein, the tubing shall meet specified requirements for workmanship, dimensions such as outside diameter and wall thickness, sustained pressure, burst pressure, oxidative resistance, and bent tubes. Quality assurance and product marking methods are also considered.
