29、3:2018ISO 23900-3:2015(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in
30、 a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commiss
31、ion (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents shou
32、ld be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for ide
33、ntifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any trade name used in this document is information given for the conven
34、ience of users and does not constitute an endorsement.For an explanation on the meaning of ISO specific terms and expressions related to conformity assessment, as well as information about ISOs adherence to the WTO principles in the Technical Barriers to Trade (TBT), see the following URL: Foreword
35、Supplementary information .The committee responsible for this document is ISO/TC 256, Pigments, dyestuffs and extenders.ISO 23900 consists of the following parts, under the general title Pigments and extenders Methods of dispersion and assessment of dispersibility in plastics: Part 1: General introd
36、uction Part 2: Determination of colouristic properties and ease of dispersion in plasticized polyvinyl chloride by two-roll milling Part 3: Determination of colouristic properties and ease of dispersion of black and colour pigments in polyethylene by two-roll milling Part 4: Determination of colouri

38、sibility in plastics Part 3: Determination of colouristic properties and ease of dispersion of black and colour pigments in polyethylene by two-roll milling1 ScopeThis part of ISO 23900 specifies a method of determining in polyethylene (PE) the colouristic properties of a test pigment relative to a
39、standard, and the ease of dispersion DHPEof pigments from the differences in colour strength on dispersing colouring materials under various conditions.Method A is appropriate for use with organic powder pigments and carbon black pigments in powder form, many of which are subject to compaction (reag
40、glomeration under pressure), for inorganic pigments in powder form and for pigment preparations in powder or flake form.Method B is appropriate for testing pigments and pigment preparations in granular form and for inorganic pigments in any form.The ease of dispersion determined in this way is valid
41、 only for the dispersion equipment, dispersion conditions and dispersion medium being used. The 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 pigmen
42、ts. The subscript DHPEis therefore used to designate the value obtained as specified in this part of ISO 23900.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

46、o entry: The DHPEis derived 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 an appropriate temperature in the polymer. The cool
47、ed milled sheet obtained in this way is then subjected to the higher shearing forces resulting from two-roll milling at a narrower gap width. The resulting increase in colour strength (see EN 12877-1) is a measure of the ease of dispersion DHPE.5 Materials5.1 Materials for method A5.1.1 Test mediumP
