Stałe urządzenia gaśnicze. Urządzenia gaśnicze gazowe. Część 1: ogólne wymagania dotyczące projektowania i instalowania. PN-EN 15004-1:2008 wersja angielska. (Warszawa : Polski Komitet Normalizacyjny, 2008)
Wymieniono wymagania i podano zalecenia dotyczące projektowania, instalowania, badania, konserwacji i bezpieczeństwa stałych urządzeń gaśniczych gazowych w budynkach, instalacjach i innych budowlach. Charakterystyki różnych środków gaśniczych i grup pożarów, dla których są odpowiednie środki gaśnicze podano w częściach 2 do 11 niniejszej normy. Ujęto systemy gaszenia przez całkowite wypełnienie odniesione do budynków, instalacji i innych specjalnych zastosowań, wykorzystujące gazowe środki gaśnicze nie przewodzące elektryczności, które nie pozostawiają pozostałości po wyładowaniu i dla których są aktualnie w dyspozycji wystarczające dane, umożliwiające aktualizację charakterystyk działania przez odpowiednią niezależną organizację.
