2 DS/EN København DS projekt: M ICS: Første del af denne publikations betegnelse er: DS/EN, hvilket betyder, at det er en europæisk standard, der har status som dansk standard. Denne publikations overensstemmelse er: IDT med: EN :2008. DS-publikationen er på engelsk. Denne publikation erstatter: DS/ENV :2000, DS/ENV :1999, DS/ENV :1999, DS/ENV :2000, DS/ENV :2004 og DS/ENV :2000. DS-publikationstyper Dansk Standard udgiver forskellige publikationstyper. Typen på denne publikation fremgår af forsiden. Der kan være tale om: Dansk standard standard, der er udarbejdet på nationalt niveau, eller som er baseret på et andet lands nationale standard, eller standard, der er udarbejdet på internationalt og/eller europæisk niveau, og som har fået status som dansk standard DS-information publikation, der er udarbejdet på nationalt niveau, og som ikke har opnået status som standard, eller publikation, der er udarbejdet på internationalt og/eller europæisk niveau, og som ikke har fået status som standard, fx en teknisk rapport, eller europæisk præstandard DS-håndbog samling af standarder, eventuelt suppleret med informativt materiale DS-hæfte publikation med informativt materiale Til disse publikationstyper kan endvidere udgives tillæg og rettelsesblade DS-publikationsform Publikationstyperne udgives i forskellig form som henholdsvis fuldtekstpublikation (publikationen er trykt i sin helhed) godkendelsesblad (publikationen leveres i kopi med et trykt DS-omslag) elektronisk (publikationen leveres på et elektronisk medie) DS-betegnelse Alle DS-publikationers betegnelse begynder med DS efterfulgt af et eller flere præfikser og et nr., fx DS 383, DS/EN 5414 osv. Hvis der efter nr. er angivet et A eller Cor, betyder det, enten at det er et tillæg eller et rettelsesblad til hovedstandarden, eller at det er indført i hovedstandarden. DS-betegnelse angives på forsiden. Overensstemmelse med anden publikation: Overensstemmelse kan enten være IDT, EQV, NEQ eller MOD IDT: Når publikationen er identisk med en given publikation. EQV: Når publikationen teknisk er i overensstemmelse med en given publikation, men præsentationen er ændret. NEQ: Når publikationen teknisk eller præsentationsmæssigt ikke er i overensstemmelse med en given standard, men udarbejdet på baggrund af denne. MOD: Når publikationen er modificeret i forhold til en given publikation.
