Résumé
Specifies a simple method for detecting the presence of certain impurities (generally water) which, dissolved at ambient temperature, cause the formation of cloudiness when the product is cooled to a sufficiently low temperature. The principle consists in determination of the temperature at which cloudiness appears in the clear sample, when it is gradually cooled under specified conditions. - Replaces ISO Recommendation R 1394-1970.
