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.
DS/EN 1993-3-1 København DS projekt: M215109 ICS: 91.090 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 1993-3-1:2006. DS-publikationen er på engelsk. Denne publikation erstatter: DS/ENV 1993-3-1:1999.

This European Standard was approved by CEN on 9 January 2006.
CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this EuropeanStandard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such nationalstandards may be obtained on application to the Central Secretariat or to any CEN member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by translationunder the responsibility of a CEN member into its own language and notified to the Central Secretariat has the same status as the officialversions.
CEN members are the national standards bodies of Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France,Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania,Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
