2 DS/INSTA København DS projekt: M ICS: Første del af denne publikations betegnelse er: DS/INSTA, hvilket betyder, at det er en fælles nordisk standard, der har status som dansk standard. DS-publikationen er på engelsk. 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.

5 Foreword This INSTA standard is based on UL 1626 Residential Sprinklers for Fire-Protection Service and is copyrighted by and reprinted with permission from Underwriters Laboratories Inc. UL shall not be responsible for the use or reliance upon a UL Standard by anyone. UL shall not incur any obligation or liability for damages including consequential damages, arising out of or in connection with the use, interpretation of or reliance upon a UL standard. Revisions of UL Standards for Safety are issued from time to time. A UL Standard for Safety is current only if it incorporates the most recently adopted revisions. This INSTA standard shall be given the status of a national standard in Denmark, Norway and Sweden either by publication of an identical text or by endorsement, at the latest by February 2010 INSTA 900 consists of the following parts, under the general title Residential sprinkler systems. Part 1: Design, installation and maintenance; Part 2: Requirements and test methods for sprinklers and their accompanying rosettes. 5

6 1 Scope This part of INSTA 900 specifies requirements for construction and performance of residential sprinklers and their rosettes which are operated by a change of state of an element or bursting of a glass bulb under the influence of heat, for use in automatic residential sprinkler systems conforming to INSTA 900-1, Design, installation and maintenance. Test methods and recommended test schedule for type approval testing are also given. The requirements in this standard are not intended to restrict the application of representative fire and other tests for special sprinklers, as referenced in EN 12845, that are intended to provide protection for specific fire hazards. A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and that involves a risk of fire or of electric shock or injury to persons must be evaluated using appropriate additional component and end-product requirements to maintain the level of safety as originally anticipated by the intent of this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
