DIN 4263:2011-06

This document applies for shapes, dimensions and geometric values of sewers and drains necessary for hydraulic calculation. It is used in water supply, wastewater engineering and general water engineering. Cross-sections with nominal widths of less than DN 40 are not subject of this standard. The following modifications have been made with respect to DIN 4263:1991-04: a) the title has been changed; b) the designations and indices have been adjusted to DWA A 110; c) formulae for determination of partial filling values have been deleted; d) the standard has been editorially revised. The Committee responsible for this standard is NA 119-05-09 AA "Allgemeine Anforderungen an Rohre, Rohrverbindungen etc. für Abwasserkanäle und -leitungen (CEN/TC 165/WG 1 und CEN/TC 165/WG 1/TG 1)" ("General requirements for pipes, pipe connections, etc. used in drains and sewers (CEN/TC 165/WG 1 and CEN/TC 165/WG 1/TG 1)") at DIN.
