Division 2.2.4.1 F1F2
United Kingdom
Flammability shall be determined by tests or, for mixtures where there are sufficient data available, by calculation in accordance with the methods adopted by ISO (see ISO 10156 as amended, ‘ Gases and gas mixtures — Determination of fire potential and oxidising ability for the selection of cylinder valve outlets ’ and, if using fundamental burning velocity for Category 1B, see ISO 817 as amended ‘ Refrigerants-Designation and safety classification, Annex C:- Method of test for burning velocity measurement of flammable gases ’ ). Instead of the test apparatus according to ISO 10156 as amended, the test apparatus for the tube method according to clause 4.2 of EN 1839 as amended (Determination of explosion limits of gases and vapours) may be used.
