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 establis
26、hed 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

Substances like aluminium silicate, barium sulfate and calcium carbonate are tak
33、en into consideration in Clauses 2 and 3.In addition to the examples of the colouring materials, the designation in accordance with the Colour Index1)has been included. However it is to be noted that for a number of the given designations of colouring materials (which are partly collective designati
34、ons) not only one designation in accordance with the Colour Index is possible, even if in this part of ISO 18451 only one Colour Index designation is given.In the “Classification scheme” in Clause 2, some spaces are empty. Corresponding colouring materials are either without practical importance or
35、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 2 and 3 but not classified in accordance with certain aspects. The reason for this is that up to now such colouring materials are excluded from th
36、e work of ISO/TC 256.1) The Colour Index (briefly: C.I.) is a work of reference existing since 1925, and comprising all usual colouring materials and dyestuff chemicals being used as their basis. It is accepted as a standard work in the field of pigment and dyestuff chemistry. ISO 2015 All rights re

43、 of inorganic and organic colouring materials in accordance with colouristic aspects2 ISO 2015 All rights reservedBS EN ISO 184512:2017ISO 18451-2:2015(E)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
44、 light scattering, independent on the wavelength.Coloured pigmentsThe optical effect is based on light absorption, dependent on the wavelength, combined with light scattering.Coloured dyestuffsThe optical effect is based on light absorption, dependent on the wavelength.Black colouring materialsThe o
45、ptical 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
46、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 materialsThe optical effect is based on their ability to absorb
47、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.
