The U. S. Army Corps of Engineers devised a system for numbering the Halon compounds, which is used worldwide. The first digit of each identifying number represents the number of carbon atoms in the molecule; the second digit, the number of fluorine atoms; the third, the number of chlorine atoms; the fourth, the number of bromine atoms; and the fifth, the number of iodine atoms. Terminal zeros are dropped. Any atoms unaccounted for are hydrogen.  4, record 43, English, - Halon%20shorthand%20naming%20system

Les halons étant très nombreux, les chimistes américains, qui les ont particulièrement étudiés, ont aussi fixé les règles de leur nomenclature. Leur formule chimique est représentée par un nombre de quatre chiffres : le premier indique le nombre d'atomes de carbone de la molécule; le deuxième, de fluor; le troisième, de chlore; et le quatrième, de brome.  2, record 43, French, - nomenclature%20industrielle%20abr%C3%A9g%C3%A9e%20Halon
