DIN Standards Committee Firefighting and Fire Protection
Fire-fighting hoses - Non-percolating layflat delivery hoses and hose assemblies for pumps and vehicles; Amendment A2
Feuerlöschschläuche - Druckschläuche und Einbände für Pumpen und Feuerwehrfahrzeuge; Änderung A2
Hoses as in this standard serve to convey fire extinguishing media. When empty, such hoses can be rolled or folded flat. This second revision A2 of the standard of DIN 14811 was necessary to bring the standard up to the current state of technology. The most important change is the subdivision of class 1 (uncovered hose) C and B hoses into three performance levels L1, L2 and L3 with regard to abrasion resistance. Amendment A2 is published separately since the discussion of comments result lead to the need of an amendment, but the market urgently requires the current A2. A consolidated new version of DIN 14811 into which all modifications will be incorporated will be published if the work on another amendment of the standard has been completed and it appears that no further amendment will be necessary. The committee responsible for this standard is NA 031-04-04 AA "Schläuche und Armaturen - SpA zu CEN/TC 192/WG 1 und WG 8" ("Hoses and armatures - Mirror Committee of CEN/TC 192/WG 1 and WG 8") at DIN.
