Overview

ISO 11922-2:1997 - Thermoplastics pipes for the conveyance of fluids - Dimensions and tolerances - Part 2: Inch‑based series - specifies standardized tolerance grades for inch‑based thermoplastic pipes. It consolidates prior single‑material standards into a unified system applicable to smooth, constant‑section extruded thermoplastic pipes, regardless of material or manufacturing method. The standard is intended as the source of dimensional tolerances to be referenced by product and system standards.
