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).

ISO draws attention to the possibility that the implementation of this document may involve the use of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent rights in respect thereof. As of the date of publication of this document, ISO had received notice of (a) patent(s) which may be required to implement this document. However, implementers are cautioned that this may not represent the latest information, which may be obtained from the patent database available at www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

This document was prepared by Technical Committee ISO/TC 256, Pigments, dyestuffs and extenders.

This third edition cancels and replaces the second edition (ISO 18451-2:2018), which has been technically revised. The changes compared to the previous edition are as follows:

— in Table 1, for manganese ferrite black (4.1.1.3) the colour index “Pigment Black 33” has been added;

— in Table 2, for ion manganese brown (5.1.1.3) the colour index “Pigment Bown 7 + 8” has been changed to “Pigment Brown 43”, and the stoichiometric formula has been modified to (Fe,Mn)2O3;

— in Table 2, for ion manganese black (5.1.1.3) the stoichiometric formula has been modified to (Fe,Mn)2O3 ∙ (Fe,Mn)3O4;

— the colour range of isoindolinone (5.2.1.5) and perylene (5.2.2.2) has been corrected.

A list of all parts in the ISO 18451 series can be found on the ISO website.

Any feedback or questions on this document should be directed to the user’s national standards body. A complete listing of these bodies can be found at www.iso.org/members.html.

Introduction

In accordance with ISO 18451‑1, it depends on the individual application as to whether a substance is to be considered as a pigment or as an extender. Substances like aluminium silicate, barium sulfate and calcium carbonate are taken into consideration in Clauses 4 and 5.

In addition to the examples of the colouring materials, the designation in accordance with the Colour Index[1] [1] has been included. However, it is to be noted that for a number of the given designations of colouring materials (which are partly collective designations) not only one designation in accordance with the Colour Index is possible, even if in this document only one Colour Index designation is given.

In the “Classification scheme” in Clause 4, some spaces are empty. Corresponding colouring materials are either without practical importance or they do not exist for physical reasons.

Inorganic dyestuffs, e.g. those for use with enamel, glass, ceramics and food, have been only mentioned in Clauses 4 and 5 but not classified in accordance with certain aspects. The reason for this is that up to now, such colouring materials are excluded from the work of ISO/TC 256.

Pigments, dyestuffs and extenders — Vocabulary — Part 2: Classification of colouring materials according to colouristic and chemical aspects

1.0 Scope

This document applies to the industry producing colouring materials and the consumer who uses the products of this industry. In this document, the colouring materials are classified in accordance with colouristic and chemical aspects.

Some dyestuffs for use in the ceramics and food industries are listed as examples.

2.0 Normative references

The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

3.0 Terms and definitions

For the purposes of this document, the terms and definitions given in ISO 18451-1 apply.

4.0 Classification of inorganic and organic colouring materials in accordance with colouristic aspects

Inorganic and organic colouring materials are classified in accordance with colouristic aspects as given in Figure 1.

 

a See Introduction.

b Corresponding products (“organic white pigments”) are at present without practical importance.

c Corresponding products (“organic white dyestuffs”) do not exist for physical reasons.

d Corresponding products (“organic effect dyestuffs”) do not exist for physical reasons.

Figure 1—Classification of inorganic and organic colouring materials in accordance with colouristic aspects

The above classification is based on optical effects the reasons of which are given in the following.

White pigments

The optical effect is based on light scattering, independent on the wavelength.

Coloured
pigments

The optical effect is based on light absorption, dependent on the wavelength, combined with light scattering.

Coloured
dyestuffs

The optical effect is based on light absorption, dependent on the wavelength.

Black
colouring
materials

The optical effect is based on light absorption, independent on the wavelength, in the visual range of light.

Effect pigments

The optical effect is based at least on one of the following effects:

 

 

in the case of metallic flake pigments on the directed reflectance of mainly flat shaped and aligned metallic pigment particles;

 

 

in the case of nacreous pigments on the directed reflectance of mainly flat shaped and aligned transparent small plates;

 

 

in the case of interference pigments on the phenomenon of light interference.

Luminous
colouring
materials

The optical effect is based on their ability to absorb radiation and to emit it as light of greater wavelength without delay with regard to time (fluorescence) or with delay with regard to time (phosphorescence).

Examples regarding the classification in accordance with colouristic aspects are given in Table 1.

5.0 Classification of inorganic and organic colouring materials in accordance with chemical aspects

Inorganic and organic colouring materials are classified in accordance with chemical aspects as given in Figure 2.

 

a Pigments that consist of more than one chemical compound and such the colouring effect of which cannot be traced back to only one constituent (e.g. multi-layer effect pigments), cannot be allocated unambiguously to a certain class.

b In this document, it is refrained from a classification of inorganic dyestuffs.

c Materials in elementary condition and alloys.
