9、controlled Copy, (c) BSI BS 5598-5:1979 ii BSI 11-1999 National foreword This British Standard has been prepared under the direction of the Chemicals Standards Committee in order to provide methods of sampling and test for halogenated hydrocarbons. For some years the United Kingdom has participated
10、in the work of preparing methods of sampling and test applicable to halogenated hydrocarbons for industrial use, organized by Sub-committee 12 “Halogenated hydrocarbons and amines” of Technical Committee 47 “Chemistry” of the International Organization for Standardization (ISO). As international agr
11、eement is reached on the methods, it is proposed to publish them as Parts of this British Standard as follows: Part 1: Sampling liquid products, identical with ISO 2209; Part 2: Sampling of liquefied gases, identical with ISO 3427; Part 3: Determination of residue on evaporation, identical with ISO
12、2210; Part 4: Determination of acidity Titrimetric method, identical with ISO 1393; Part 5: Determination of cloud point, identical with ISO 1394; Part 6: Determination of acidity of fluorochlorinated hydrocarbons, identical with ISO 3363; Part 7: Methods of test for methyl chloride and ethyl chlori
13、de, identical with ISO 57811); Part 8: Determination of non-volatile residue in fluorinated hydrocarbons, identical with ISO 57891). This Part is identical with ISO 1394 “Liquid halogenated hydrocarbons for industrial use Determination of cloud point” Terminology and conventions. The text of the Int
14、ernational Standard has been approved as suitable for publication, without deviation, as a British Standard. Some terminology and certain conventions are not identical with those used in British Standards; attention is especially drawn to the following. The comma has been used as a decimal marker. I

With reference to clause 4.1, the mixture of acetone and solid carbon dioxide may be made by cooling a suitable amount of acetone in the 1 000 ml beaker to a temperature of 12 C or lower by means of a mixture of ice and salt
20、. An amount of solid carbon dioxide sufficient to produce the required temperature is ten added by means of a wood or plastic spatula. This standard specifies a method of test only and should not be referred to as a specification defining limits of purity. Reference to the standard should be in the
