Published By	Publication Date	Number of Pages
ISO	1972-03	5

]]> The method is not specific for phenol. It determines tho total amount of material that can be brominated under the conditions of the test. It is applicable to mixtures of about 80 % (V/V) phenol and 20 % (V/V) water. The principle is based on reaction between phenol and bromine from a measured amound of standard bromide/bromate solution. Formation of tribromophenol, follwed by iodometric determination for excess bromine using a standard volumetric solution of sodium thiosulphate.

Published By	Publication Date	Number of Pages
ISO	1977-04	7

]]> This method is the best available at the present time. It was primarily intended for samples containing 40 % (m/m) or more but has been extended to lower ranges. The principle is based on dehydration of a quantity of the test sample. Formation of a complex between o-cresol and cineole (having a crystallizing point not lower than 1,2 °C) by addition of excess cineole to a test portion of the dehydrated sample. Determination of the crystallizing point of the complex in a crystallizing point apparatus. Calculation of the content from the water content of the test sample and the crystallizing point of the complex. The relation between crystallizing point and o-cresol content of o-cresol/cineole mixtures is given in a table. ISO 1897/8 replaces ISO Recommendation R 1910-1971.

ISO	1977-04	4

]]> Specifies a method for the comparison of the colour of a test portion against the colour of colorimetric standard colour matching solutions. The colour of cresols present in the test portion is liable to darken on keeping and on exposure to ligth. ISO 1897/7 replaces ISO Recommendation R 1909-1971.

ISO	1977-04	6

]]> Simple empirical test of no great precision. The principle consists in shaking a test portion with sodium hydroxide solution under specified conditions and assessment of any insoluble matter present in suspension in the mixture by comparison either with an agreed standard turbidimetric solution or with sodium hydroxide solution. The comparison of the turbidity of the two solutions is carried out by viewing vertically and with the electric lamp equipped with a ligth blue dayligth-bulb switched on.
