introduction
ИСО (Међународна организација за стандардизацију) је глобални савез националних тела за стандардизацију (Тела чланица ИСО). Развој међународних стандарда се обично спроводи преко ИСО техничких комитета. Свака институција чланица заинтересована за тему за коју је основан технички комитет има право да буде заступљена у тој комисији. Међународне владине и невладине организације које су у вези са ИСО такође су укључене у овај посао. ИСО блиско сарађује са Међународном електротехничком комисијом (ИЕЦ) о свим питањима електричне стандардизације.

This document was prepared by the ISO/TC 256 Technical Committee on Pigments, Dyes and Fillers.
The first edition of ISO 1247-1, together with ISO 1247-2, eliminated and replaced the technically revised ISO 1247-1974. It also incorporates amendments to ISO 1247:1974 /Amd 1:1982.
Главне промене у односу на претходно издање су следеће:
– Added an introduction explaining the reasons for the division;
– The addition of article 3, Одредбе и дефиниције, and the inclusion of terms such as “non-volatile substances” и “covering power”;
ИСО 1247-1-21 Алуминијумски пигменти за боје – Део 1: Општи алуминијумски пигменти
– The distinction between surface treated and surface untreated aluminium pigments is introduced in articles 4 и 5;
– Deletion of the former paragraph 4.2 “classes”;
– “105°C volatile substances” до “non-volatile substances”;
– Delete the original article 6 “packaging”;
– Article 7, sampling, has been simplified to a reference to ISO 15528;
– Table 1 adds the requirements and test methods of “pigment specific surface area”, “particle size distribution” и “hiding power” and the corresponding test methods, and is renamed “Requirements and test methods”;
– The test method of “manganese” is deleted from the metal impurities in Table 1;
– Flame atomic absorption spectrometry was introduced to determine metal impurities;
– Delete the original article 13 “unregulated blade force test”;
– Table 3, the test section, has been deleted;
– Article 16 has been added to determine concealment forces;
– The normative references have been updated and the text has been edited and revised.

увести
Since the beginning of the new millennium, with advances in technology and product development, new aluminum pigments have flourished, and these aluminum pigments are used in a wide range of industrial sectors as heat or rust resistant coatings or colorants. Aluminum pigments can be conveniently divided into two groups according to their form: general aluminum pigments produced during milling and vacuum metallized aluminum pigments (VMP) (see ISO 1247-2). Because of the different technical requirements for aluminum pigments used in different fields, it is necessary to develop an international standard for each of these two groups.
In order to meet the needs of aluminum pigment marketing, this document describes the characteristics of “particle size distribution” и “hiding power” and their corresponding test methods.
In order to improve the safety of aluminium pigments, low flash point organic solvents and additives have been replaced by high flash point reagents, “105°C volatile substances” has been replaced by “non-volatile substances”, and test methods have been developed according to ISO 3251.
The previous edition (тј. ИСО 1247:1974) used different spectrophotometric methods for the determination of lead, iron and copper, and ethylenediamine tetraacetic acid (EDTA) titration for the determination of zinc. These methods are cumbersome to operate. The method used to determine lead involves the use of potassium cyanate, a highly toxic agent rarely used since the 1990s, and the method used to determine zinc is only suitable for samples with a total zinc content of 0.10% or more, and is not suitable for the current state of the aluminum pigment industry. While these old methods are retained in this document, flame atomic absorption spectrometry is introduced as a new option for the determination of the above-mentioned metal impurities. This method is faster, easier to operate, has a wider detection range, and is becoming more and more popular.

In order to use as few toxic agents as possible, this document uses 2-butoxyethanol or n-butyl acetate instead of acetone, which is now banned or restricted in many countries as a material that may be used in the manufacture of illicit drugs.

3 Одредбе и дефиниције
За потребе овог документа, термини и дефиниције дате у ИСО 18451-1, ИСО 18451-2 а примењују се следећи чланови.
3.1 Non-volatile substances
A mass residue obtained by evaporation under specific conditions
Белешка 1: Different terms in place of the term “non-volatile substance”, such as solids, dry residues, dry matter, solid substances, baking residues are often used together with their respective abbreviations. Термин “non-volatile substances”, which also applies in ISO 3251, should be used together with the abbreviation “NV” instead of these terms.
[Извор: ИСО 4618:2014, 2.176]
3.2 Hiding power
The ability of a coloring medium to hide the color or chromatic aberration of a substrate
[Извор: ИСО 18314-2:2015, 2.1.6]
