Thermoplastics pipes for the conveyance of fluids. Dimensions and tolerances. Inch-based series | Status: Current, Under review

1 Scope This part of ISO 11922 specifies tolerance grades for the outside diameter, out-of-roundness and wall thickness of inch-based thermoplastics pipes for the conveyance of fluids and manufactured with nominal outside diameters and nominal pressures in accordance with ISO 161-21[1](see annex A). It is applicable to smooth thermoplastics pipes of constant circular cross-section along the whole length of the pipe, whatever the method of manufacture, the pipe material or the intended application.

NOTE — It is intended that the tolerance grades specified in product standards be selected from this part of ISO 11922, taking into account the material and the intended application.
