Scope

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 shall only be used in automatic sprinkler systems for domestic and residential applications as defined in EN 16925.

Purpose

Sprinklers having a broad range of dynamic o-ring water seal constructions have experienced inhibited operation and deficient water seal performance in field environments. Additional testing beyond those tests specified in this standard is necessary to establish the proper performance of these sprinklers in field environments. Therefore, the scope needs to be revised so that o-ring sprinklers are not included. At the same time, we would propose we remove the test for this purpose in Annex I-3 and any references to it.
