Stałe urządzenia gaśnicze : Urządzenia gaśnicze gazowe - Część 1: Projektowanie, montaż i konserwacja. PN-EN 15004-1:2025-05 - wersja angielska - Polski Komitet Normalizacyjny (Warszawa : Polski Komitet Normalizacyjny, 2025)
W niniejszym dokumencie określono wymagania i zawarto zalecenia dotyczące projektowania, instalacji, testowania, utrzymania i bezpieczeństwa stałych urządzeń gaśniczych gazowych w budynkach, zakładach lub w innych obiektach oraz określono charakterystyki gazów gaśniczych, jak też rodzaje pożarów, dla których są odpowiednimi środkami gaśniczymi. W niniejszym dokumencie uwzględniono urządzenia działające przez całkowite wypełnienie związane z budynkami, zakładami i innymi specjalnymi zastosowaniami, wykorzystujące nieprzewodzące prądu gazowe środki gaśnicze, które nie zostawiają pozostałości po wyładowaniu i dla których istnieją wystarczające aktualnie dostępne dane, umożliwiające zatwierdzenie w zakresie charakterystycznych właściwości i bezpieczeństwa przez właściwy niezależny organ. Niniejszy dokument nie ma zastosowania do urządzeń tłumiących wybuchy. Niniejszy dokument nie ma na celu potwierdzenia, że ​​właściwe organy zatwierdziły wymienione w nim środki gaśnicze, gdyż inne środki gaśnicze mogą być równie dopuszczalne. Nie uwzględnia się CO₂, ponieważ odnosi się do niego własna Norma Europejska. Niniejszy dokument ma zastosowanie do środków gaśniczych wymienionych w Tablicy 1. Istotne jest, aby niniejszy dokument stosować w połączeniu z pozostałymi częściami EN 15004 w odniesieniu do poszczególnych gazów gaśniczych, wymienionych w Tablicy 1.
