9、d, both nationally and internationally, covering fire extinguishing media. It is identical with ISO7201 “Fire protection Fire extinguishing media Halogenated hydrocarbons” Part1:1989 “Specifications for halon1211 and halon1301”, published by the International Organization for Standardization. Itis a
10、 new edition, containing editorial and other corrections toBS6535-2:1984, which was identical with ISO7201:1984. It is renumbered as Section2.1 as a consequence of the publication of BS6535-2.2 Code of practice for safe handling and transfer procedures. This edition supersedes BS6535-2:1984 which is
11、 withdrawn. In1994 the European Committee for Standardization (CEN) accepted ISO7201-1:1989 as European Standard EN27201-1:1994. As a consequence of implementing the European Standard, this BritishStandard is renumbered asBS EN27201-1 and any reference to BS6535-2.1 should be read as a reference toB
12、S EN27201-1. Marking. With reference to7.2 d), containers may, alternatively, be marked with the number of this BritishStandard, i.e.BS6535-2.1:1990 1) . The International Standard has a foreword which is as follows. “This International Standard is one of a series giving specifications for fire exti
13、nguishing media in common use and which are in need of standardization for fire fighting purposes. These specifications are designed to establish that the medium in question has at least a minimum useful fire extinguishing capability and can therefore be reasonably sold for fire extinguishing purpos
14、es. Requirements for media used in particular equipment will form the subject of future International Standards.” Cross-references International Standard Corresponding BritishStandard ISO3363:1976 BS5598 Methods of sampling and test for halogenated hydrocarbons Part6:1979 Determination of acidity of

The text of the Internatio
26、nal Standard ISO7201-1:1989 was approved by CEN as a European Standard without any modification. This European Standard is only available in the English and French versions. In accordance with CEN Regulations the foreword to the ISO standard is not included in this European Standard. The following w
27、arning which does not appear in the foreword to the ISO standard, is included here with the agreement of CEN/TC 191. WARNING. Halon 1211 and halon 1301 are listed in the Montreal Protocol on Substances that Deplete the Ozone Layer. There are agreements which limit their use. Users of this European S
28、tandard are advised to consult the relevant authorities on these matters when supplying or handling halon 1211 or halon 1301. Compliance with this European Standard does not in itself confer immunity from legal obligations. This European Standard shall be given the status of a national standard, eit
29、her by publication of an identical text or by endorsement, at the latest by November1994, and conflicting national standards shall be withdrawn at the latest by November1994.

31、bons for use as fire extinguishing media: a) halon1211 bromochlorodifluoromethane (CF 2 ClBr); b) halon1301 bromotrifluoromethane (CF 3 Br). This part of ISO7201 does not deal with the conditions of use of these products in fire fighting equipment. Such equipment (portable fire extinguishers, fixed
32、installations, etc.) will be dealt with in future International Standards. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO7201. At the time of publication, the editions indicated were valid. All standa
33、rds are subject to revision, and parties to agreements based on this part of ISO7201 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO3363:1976

ISO5789:1979, Fluorinated hydrocarbons for industrial use Determination of non-volatile residue. 3 Definition For the
35、purpose of this part of ISO7201, the following definition applies. halon a halogenated hydrocarbon used as a fire extinguishing medium NOTEThe following numbering system is used to identify halons. The word “halon” is followed by a number, usually of four digits, giving, in turn, the number of carbo
36、n, fluorine, chlorine and bromine atoms. Terminal zeros are omitted. Thus halon1211 is bromochlorodifluorobromomethane (CF 2 ClBr) and halon1301 is bromotrifluoromethane (CF 3 Br). 4 Requirements Halons1211 and1301 shall comply with the requirements of Table 1, when tested by the appropriate method
37、of test specified in clause6. Table 1 Requirements 5 Sampling Samples of halons shall be taken from the manufacturers shipping container using the method specified in ISO3427. 2) 6 Methods of test 6.1 General For all tests, the sample shall be taken from the liquid phase. 6.2 Purity Determine the pu
38、rity by gas-liquid chromatography, using generally accepted laboratory techniques. 6.3 Acidity Determine the acidity by the appropriate method specified in ISO3363. 6.4 Water content Determine the water content by the orthodox KarlFischer method or by any other method giving equivalent results.

NOTEThe containers may need to comply with national regulations. 7.2 Containers shall be marked with the following information: a) suppliers name and address; b) “Halon1211” or “Hal

Halon 13
44、01 is an odourless gas. A number of their other more important physical properties are given in Table A.1. A.2 Electrical conductivity Halons 1211 and 1301 have a very low electrical conductivity. In many cases they can be used to extinguish fires involving live electrical equipment, but this, to a
45、significant extent, may depend on the circumstances, particularly the method of discharge. In case of doubt, reference should be made to the instructions on the fire extinguishing equipment to be used.
