BS ISO 4065:2018

This standard BS ISO 4065:2018 Thermoplastics pipes. Universal wall thickness table is classified in these ICS categories:

• 23.040.20 Plastics pipes

This document specifies the relationship between the nominal wall thickness e_n and the nominal outside diameter d_n of thermoplastics pipes.

It is applicable to solid-wall thermoplastics pipes of constant circular cross-section along the whole length of the pipe, whatever their method of manufacture, their composition or their intended application.

NOTE Pipes with constant circular cross-section along the whole length of the pipe are commonly known as pipes with smooth external and internal surfaces.
