Specifies the sampling, the determination of distillation characteristics, the determination of density at 20 °C, the determination of crystallizing point, the determination of residue on evaporation, the determination of water and the determination of acidity. The determination of distillation characteristics indicates the difference between the temperatures corresponding to the collection of…
Methylene chloride for industrial use — List of methods of test
Specifies the sampling, the determination of residue on evaporation, the determination of distillation characteristics, the determination of density at 20 °C, the determination of acidity, the determination of water and the measurement of colour. The determination of distillation characteristics indicates either the temperatures corresponding to the collection of each of two volumes of distillate…
Chloroform for industrial use — List of methods of test
Specifies the sampling, the determination of distillation characteristics, the determination of density at 20 °C, the determination of water, the measurement of colour and the determination of acidity. The determination of distillation characteristics indicates either the temperatures corresponding to the collection of each of two volumes of distillate, V0 and V1, or the difference between these…
Liquid halogenated hydrocarbons for industrial use — Determination of acidity — Titrimetric method
The method does not apply when the halogenated materials hydrolyse at ambient temperature. The principle is based on the titration of the acidity of the aqueous extract from a test portion with a standard volumetric sodium hydroxide solution in the presence of bromocresol green as indicator. - Replaces ISO Recommendation R 1393-1970.
Liquid halogenated hydrocarbons for industrial use — Determination of cloud point
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. -…
Phthalic anhydride for industrial use — Methods of test — Part 1: General
This document also specifies a method to be used for the determination of the crystallizing point. Before carrying out the analysis and tests, the sample shall be grind to a fine powder and mixed thoroughly. Exposure to moist air may lead to the formation of phthalic acid. - ISO 1389, Parts 1 to 11, replace ISO Recommendation R 1389-1970.
Phthalic anhydride for industrial use — Methods of test — Part 2: Measurement of colour of the molte...
The principle is based on the measurement of colour, by the method specified in ISO 2211, of a test portion in the molten state. The results are expressed in Hazen units. - ISO 1389, Parts 1 to 11, replace ISO Recommendation R 1389-1970.
Phthalic anhydride for industrial use — Methods of test — Part 3: Measurement of colour stability
The principle is based on the measurement of the colour of a test portion, by the method specified in ISO 2211, after a specified heat treatment. The test sample is maintained in a colorimetric tube in an electrically heated aluminium block, controlled at (250 3) °C for 90 min, in the molten state. The results are expressed in Hazen units. - ISO 1389, Parts 1 to 11, replace ISO Recommendation R…
