This document specifies requirements for the construction and performance of residential sprinklers as well as test methods for their type approval, which are operated by a change of state of an element or bursting of a glass bulb under the influence of heat and incorporating the following types of water seals: – conical metal spring with a PTFE gasket or coating; – metal cap or disc with PTFE gasket or coating; – copper gasket, with or without a PTFE coating. Sprinklers in accordance with this document will only be used in automatic sprinkler systems for domestic and residential applications as defined in EN 16925.
