ISO 23900-1:2015 顔料と増量剤—プラスチックの分散方法と分散性の評価—パート1：一般的な紹介 | ページ 2

Foreword

ISO (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 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 Commission (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 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 ).

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 identifying 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 convenience of users and does not constitute an endorsement.

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 introduction
• 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 colouristic properties and ease of dispersion of white pigments in polyethylene by two-roll milling
• Part 5: Determination by filter pressure value test
• Part 6: Determination by film test

1 Scope

This part of ISO 23900 provides an introduction to the various parts of ISO 23900 which describe methods for dispersing pigments and extenders in plastics materials in order to determine their dispersion characteristics and colouristic properties.

Methods of assessing dispersion characteristics are described in the subsequent parts of ISO 23900.

The various procedures described permit comparison to be made between similar pigments (for example between a test sample and an agreed reference pigment). The results provide an indication of relative dispersibility under practical conditions of use, provided that the test procedure and plastics material selected are appropriate.
