11、dies (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 organizatio
12、ns, governmental 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
13、 maintenance 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)

20、ee of dispersion of a colorant in a thermoplastic polymer.The method is suitable for testing colorants in the form of colour concentrates in all polymers used for extrusion and melt-spinning processes.The filter pressure value (FPV) determined according to this method is valid only for the equipment
21、, conditions and test polymer being used. The use of test conditions differing from those specified might give different results. The method of preparing the colour concentrate is not specified in this part of ISO 23900. The results obtained for individual colorants are therefore comparable only whe
22、n the same method of preparation for colour concentrates is used.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
