ISO 161-1:2018 PDF

Scope: This document specifies the nominal outside diameters for metric thermoplastics pipes for the conveyance of fluids in pressure and non-pressure applications. It also specifies nominal pressure ratings and minimum required strengths for pressure applications. It is applicable to smooth thermoplastics pipes of constant circular cross-section along the whole length of the pipe, whatever their method of manufacture or material of construction. It is not applicable to pipes designated according to the nominal inside diameter DN/ID. This document is a basis for standards writers for the selection of nominal diameters and nominal pressures in the drafting of product standards.
