29、ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, go
30、vernmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maint
31、enance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Atten

38、1 ScopeThis part of this ISO 23900 specifies a method of determining the colouristic properties of a test pigment relative to a standard, and the ease of dispersion DHPVC-Pof pigments from the differences in colour strength on dispersing colouring materials under various conditions in plasticized po
39、lyvinyl chloride (PVC-P) compounds.The method is appropriate for use with organic and inorganic black and colour pigments and for pigment preparations.The ease of dispersion determined in this way is valid only for the dispersion equipment, dispersion conditions and dispersion medium being used. The
40、 use of test conditions differing from those specified may give different results; this applies both to the absolute magnitude and to the relation between values of the ease of dispersion of various pigments. The subscript DHPVC-Pis therefore used to designate the value obtained as specified in this
41、 part of ISO 23900.The principle of this part of ISO 23900 may also be used for routine quality control purposes by reference to the photometric data generated from the sheets milled at 130 C. For quality control purposes, the ratio of pigment to TiO2may be agreed between the interested parties. Rat
42、ios of 1:10 for organic pigments and 0,2 to 0,5:1 for inorganic pigments are suggested as convenient and widely used standard ratios.Annex A is informative and gives a description of a suitable basic compound.2 Normative referencesThe following documents, in whole or in part, are normatively referen

47、from the increase in colour strength achieved by two-roll milling as specified in 8.2, relative to the colour strength achieved as specified in 8.1.4 PrincipleUsing a two-roll mill, the pigment under test is dispersed at (160 5) C in the basic compound. The milled sheet obtained in this way is then
48、subjected to the higher shearing forces resulting from two-roll milling at (130 5) C. The resulting increase in colour strength is a measure of the ease of dispersion DHPVC-P.5 MaterialA suitable and recommended basic compound is described in Annex A. An alternative compound may be agreed between th
