prEN ISO 787-4
Tähtaeg 2.05.2017
General methods of test for pigments and extenders - Part 4: Determination of acidity or alkalinity of the aqueous extract (ISO 787-4:1981)
The principle of the method consists in the hot extraction of the material by following the procedure specified in ISO 787/3, to the stage of obtaining a perfectly clear filtrate. The determination is carried out with indicator solution (method A). If the solution with the methyl red indicator is yellow (alkaline), titrate it with the hydrochloric acid solution to an orange end-point; if the solution with the methyl red indicator is red (acid), titrate it with the sodium or potassium hydroxide solution to an orange end-point. The other method (method B) is the potentiometric determination. Take 100 ml of the test solution, insert the electrodes of the pH measuring device and read the pH value.

prEN ISO 787-1
Tähtaeg 2.05.2017
General methods of test for pigments and extenders - Part 1: Comparison of colour of pigments (ISO 787-1:1982)
Procedure for comparing the colour of a coloured pigment with that of an agreed sample. The procedures described in this document are acceptable but the method using an automatic muller is the reference method. The binder is not specified. It shall be agreed between the interested parties. If no binder is agreed, linseed oil, complying with the specification in ISO 150, should be used. - Replaces ISO/R 787/1:1968.

Tähtaeg 2.05.2017
General methods of test for pigments and extenders - Part 17: Comparison of lightening power of white pigments (ISO 787-17:2002)
This part of ISO 787 specifies a general method of test for comparing the lightening (reducing) power of a white pigment with the lightening power of an agreed sample of the same type. Two procedures (A and B) are described. Procedure A is quicker than procedure B and is suitable for testing one sample of pigment; procedure B is better for testing several samples, and especially if a pigment of unknown lightening power is being tested.

Tähtaeg 2.05.2017
General methods of test for pigments and extenders - Part 21: Comparison of heat stability of pigments using a stoving medium (ISO 787-21:1979)
The method is intended for comparing the heat stability by specifying the temperatures of heating and the time of heating; it may also be used for determining the heat resistance of a pigment. The comparison of heat stability is carried out against that of an agreed sample.

Tähtaeg 2.05.2017
General methods of test for pigments and extenders - Part 22: Comparison of resistance to bleeding of pigments (ISO 787-22:1980)
Specifies a method for comparing the resistance to bleeding with that of an agreed sample. The method has been established because it is essentially a practical test and as such is probably of greater general value than other methods.
