Fire protection -- Automatic sprinkler systems -- Part 5: Requirements and test methods for deluge valves
Performance and test requirements for other auxiliary components or attachments to deluge valves are not covered by ISO 6182-5:2012.
ISO 6182-5:2012 does not cover thermally operated valves released by heat acting directly on the valve. This type of valve utilizes a thermal device, such as the link-and-lever arrangement or glass bulb of a sprinkler, to hold the valve closed. Operation of the thermal device allows the valve to open.
