scope:

This standard specifies the test method for cables designed to have intrinsic resistance to fire and intended for use as emergency circuits for alarm, lighting and communication purposes. This standard is applicable to cables, for emergency circuits, of rated voltage not exceeding 600/1000 V, including those of rated voltage below 80 V and for emergency circuit optical fibre cables. The test method includes an optional mean of applying a water spray to the cable during the test. Although there is no requirement under the Construction Products Directive for cables to withstand water spray when assessing resistance to fire, such a requirement may be a feature of national standards or codes of practice. Guidance for using the optional water spray protocol is given in Annex F.
