This European Standard specifies the test method for optical fibre cables with an overall diameter not exceeding 20 mm designed to have intrinsic resistance to fire and intended for use as emergency circuits for alarm, lighting and communication purposes. The test method, which is based on the direct impingement of flame from a propane burner giving a constant temperature attack of a notional 842 °C, can be used for cables for emergency circuits required to comply with Subclause 4.3.1.4.6 (a) of the Interpretative Document for Essential Requirement No. 2 'Safety in Case of Fire' (94/C62/01) of the Construction Products Directive (89/106/EEC). This standard includes (Annex C) a means of linking the measured survival time to the fire resistance classification for these cables, as required by Subclause 4.3.1.4.6(a) of 94/C62/01. The standard also includes (Informative Annex D) a means of applying a shock producing device and also (Informative Annex E) means of applying a water spray to the cable during the test, together with a shock.
